Ford 6.0L Power Stroke Diesel :: Consistently Cranks For Around 5 Seconds Before It Starts
Jun 20, 2017
Where to monitor or what to check. The past few weeks this truck all the sudden went from a quick starter(barely hit the key and it would pop off) cold and hot to one that consistently cranks for around 5 seconds before it starts. Doesn't matter if I wait for the glow plug dash light to go out when it's sat for two days or if the engine has a ECT of 198 F and was just running 5 minutes prior...it still cranks over for 5 seconds before starting. Seems like it's an electronic issue vs mechanical, but that's just a guess.
The truck runs, drives and tows excellent outside of this starting quirk...so I know I shouldn't complain but this isn't right from what it used to start like and seems like it's a warning that something is likely to fail down the road. I'd Rather find it now than when 100's of miles from home if possible.
I updated it with better dummy plugs, standpipes, STC fitting, rebuilt FICM, 2 fresh batteries, new fuel pump, ICP sensor all within the last 10K miles. I scanned it with a code reader and found no codes in the history and the check engine light is not on.
Monitoring with a Scan Gauge all inputs seem normal for what I've read on this website with the exception of SYC it says 0? Which should mean it would never start I think but yet it does? I checked my code numbers from the list and I had it entered correct. Is this my issue a bad crank or cam position sensor?

Lately it seems that my 6.0 cranks over longer before it starts. it used to turn over quick and start not it turns over at least 5-8 seconds maybe more. .

I have a 2004 F250 Superduty with the 2003 6.0 Powerstroke inside of it. In the morning i can go out and start the truck perfectly fine starts up and runs like a champ, it will drive to any destination perfectly fine with no issues, ALTHOUGH .... once i reach where im going if i turn the truck off it will not start correctly. it cranks over and will start but sounds as if it is hydrolocking and in a matter of seconds kills itself. once it does this i have to let the truck sit for a minimum of 4-5 hours with the hood popped to allow motor to cool... as soon as its cooled completely i can start it and once again it runs perfectly fine until i turn it off again. if i leave it running at an idle it will sit and idle all day long and i can jump in and drive it fine. It just happens when it gets turned off.

I have a PS 6.0 in my '04F350 that starts very reliably but stalls within 1-2 seconds. Restarts after cranking for 5-30 seconds. This only occurs if the truck sits for more than 6 hours. The longer the truck sits, the longer it has to crank to restart. Also if the tank is full and the truck is parked pointing down hill this does not occur, if it is parked pointing up hill it occurs even with a full tank. Shows no codes. I've had several mechanics look at it and no one has been able to explain or propose a solution expect for wholesale replacement of parts. The symptoms indicate to me that air is getting into the fuel system but I'm not sure where to look.

Is there an alert setting to signal when a regen starts? My engine stumbles badly a few seconds after a regen starts. The dealer hasn't found the problem. Right now I just keep an eye on the soot level gauge.

I am lost on what I need to do with my 2005 6.0. Last summer it started giving me trouble once in a while starting. I turn the key on and wait for the wait to start light to go out. When it goes out, turn the key and it starts, most of the time. Last summer I went to start it the same way, only it cranked and did not start. I turned the key off, back on and cycled the wait to start light again and turned to the start position, it started right up. Whenever it would act up I just turn the key off then back on and it starts right up. Usually on the second try, but lately it has taken 3 or more tries. I am not finding any real pattern to when it wont start.
When it does not start I can crank on the starter until the battery dies and it wont even think about starting. Turn the key off and back on, it will start.
Another thing I have noticed, when I crank the engine I can hear a clicking from under the hood right before it starts. I think it must have something to do with the injectors. I will crank the engine a few seconds, hear the clicking then it starts. If I don't hear the clicking it will not start, so when it doesn't want to start I also do not hear the clicking sound.
The other day I started it, drove 5 or 6 blocks and shut it off. After 20 minutes or so went to leave. I had to cycle the key 4 or 5 times off and back on before it decided to start. It is getting worse, doing it more frequently, and taking several times of key off and back on to get it going. Where should I start looking to find this problem?

I have now replaced hpop, injectors, cups, gpr, batteries, uvch on both sides, icp and ipr on my 2002 F550 and it still has a long crank to start.
It has been driven about 1,000 miles since then and no change. I have no codes except buzz test produced a high to low 1272 1274 1276 1278 one time. Cannot get that to happen again.
It is taking 4 seconds of cranking to start consistently hot or cold. It always starts but cranks for what seems like too long compared to my other 7.3s. I have included a screenshot of the data and am curious on what everyone's thoughts are as I am out of things to look at!

Truck stalls out and cranks hard for 7-10 seconds before starting if I don't let it warm up adequately before I start driving. Transmission is hesitant to shift. Also, white smoke comes out exhaust if it's cold and I get in the throttle too much or if I hit 70+mph.

I am a longtime 7.3 IDI guy with an 88 F350 crew so i know about diesels. But this is my first electronic diesel. I picked up a 2001 F450 2wd auto 260k miles. it used to be my work's truck but was stitting for a year and now i got it in "non running condition"
I towed it home and got it started by replacing the batteries and using the block heater.
As expected it took a few tries of long cranking to run the first time. runs pretty good and no smoke. what surprised me is it still takes about 5 sec of cranking to restart each time when warm too. any direction you would look with those symptoms? HPOP, IPR?
i am pretty sure the glow plugs all work because mechanics had replaced all that stuff. but i know back when the truck was last used it would still never start cold unless plugged in (even in summer).

Trucks been running perfect for 11,000 miles atleast. its last issue was a bad turbo but that was my fault. No issues whatsoever since. 10 miles down the road from work last night truck had a slight miss in between 55-60 for four or five seconds, I put the pedal down and brought it up to 75 or so just to see if it was my imagination and it felt fine so i wrote it off. It ran fine to the house we're working on i wanted to check on before I got home.
Parked it, it idled down to 650 before it came back up to 750 and it never does that and sounded different then it usually does. so i felt something was definitely up. i shut it off, was at the house about a half hour before i decided to head home, started and ran fine, three miles down the road the slight miss came back, it seemed to go away if i got on it pretty good and when i let off but just cruising with slight throttle it had the slight miss.
Got to my road where i had to slow down and turn and it idled down and died. I coasted over, unplugged the icp sensor and it cranked for 10 seconds or so and lazily came back to life. I got it home running decent and parked it. Scanned it with my old super chips tuner and it came up with a p0340 camshaft position code.
Matched my symptoms i felt so this morning i decided id go back to work and grab my spare out of my wrecked truck. truck started and idled perfect. made it to the end of my driveway before the miss came back and then it just died. took the car to work, grabbed my spare camshaft sensor and my maximus scanner, came home scanned it, no returning p0340 cam code but i swapped the camshaft sensor anyway and watched icp and ipr data, the ipr voltage is where it should be and rises while cranking while cranking.
ICP is climbing to almost 3,200 psi and it will begin to run when it peaks out. she'll fire for 45 seconds after 25 seconds of cranking or so and then it'll just die. if it sits for a few minutes it takes a few seconds of cranking before ICP will come off of 0. I've come to the conclusion that it is making high pressure oil it is just dumping it as fast as it can make it. I changed the ipr out because that can do it, it didn't change anything so I'm on to believing an injector is dumping it as fast as possible.
Is it possible for something to come undone inside the injector to make it dump high pressure oil or will a bad o ring cause this? i'm leaning towards a failing injector as when it does fire and run its definitely misfiring and i just put new o rings on them when i swapped them over from my wrecked truck but that was like 45,000 miles ago as well..

I have a 2002 F-450 crew cab 2wd automatic 7.3 diesel with 298k on the body and about 120k on a Jasper engine. About a month ago I started it in the morning to let it warm up. Went to make coffee. Came back and it had died. It was low on fuel and I didn't pay attention. Played hell getting it primed back up. Now if I don't let it warm up for twenty minutes it won't run worth a flip and has been dying out. Changed fuel filter. Unplugged ICP. No change. When I crank it it will turn over for about thirty seconds then oil pressure gauge moves, then engine starts to run very roughly. It will die. I repeat a few times. It will eventually start and start and stay running. Blows whitish grey smoke until it warms up. No loss in power till CEL comes on. Still not too much loss. Sometimes it takes a long time to get it running. Sometimes it will die after I get out of the driveway if I don't let it warm up. Truck was serviced maybe 3000 miles ago. No water in fuel. New fuel filter. New air filter. It is a company truck. I work for a small company building cell towers.

Like usual, i have a problem that no one else has and it sounds like its something electrical/sensor/PCM related.
Every few mornings, ill go out to my truck and go to fire it up...and it'll just crank away. After i give up on cranking and shut the key off, go to try again, it fires up instantly, like nothing is wrong. Sometimes in the morning itll just have an extended crank but eventually start. Regardless...it always starts. Sometimes it cranks really strong the entire time, sometimes the crank gets weaker the longer you crank...i don't think its HPO related, but i definitely could be wrong.
Ficm voltage looks good KOEO, cranking and running. I had my batteries tested at ford a few weeks ago and they "said" they were good (motorcraft 850ccas). Alternator is strong. When cranking, ive seen the voltage drop anywhere from 10.2 to 9.4v. I never know when this is going to happen and i can't hook up AE every morning and sit and wait, but based on my scangauge, i see ICP shoot up to over 1500 as soon as it fires.
Only code I've gotten is P0148, which is fuel delivery error/engine speed higher than expected. I've gone ahead and replaced my camshaft position sensor with a ford sensor a few days ago...it hasn't done a no-start yet, but it did do an extended crank. I think my next stop is PCM replacement...

New alternator, fairly new batteries....after sitting 5 days or more, it cranks but no start.....put on charger for four hours, it fires right up...
Voltage on the multimeter shows 12.45 on both batteries......could there be something drawing down the amps? If so how do I find it?

Well, last night I took my F-350 up a wheeling trail. I'd been up quite a few times in my old Rover, so I knew I could go a ways in without damage. Just uphill, muddy, and ruts / rock steps.
One thing I notice is that when you engage low range in the diesel, the transmission starts in 2nd gear. My previous gas Super Duties always started in 1st. I'm assuming this is to protect the transfer case from torque overload. Also, the throttle response seems to change when low is engaged (the pedal becomes less responsive, which is nice).
I've had the gas Super Duties off road before, and all of mine have had the locking rear diff. The diesel lugged along perfectly. My biggest fear was crunching the DPF / SCR / DOC canister on a rock step. In that respect, I'd rather wheel a gas. The manual shift function makes a lot of sense in low range - you can force a start in 1st, 2nd, or 3rd. And prevent meaningless up / down shifts since the grade can change quickly.
These trucks' biggest hindrance is their size. However, if you have the trail room, they are actually excellent off road. Many people look at a Super Duty and see a vehicle good only for pulling or hauling. Not so, these trucks are as good as a Jeep off road, again with trail room being the only concern. The locking rear diff was never really needed, but I engaged and disengaged a few times to keep the mechanism free. I really love this feature.
One thing that happens frequently for me in north-east wheeling is water crossings. Could be a simple brook but mostly it is mud holes encountered on tight trails. In some cases these are only a foot or so deep; in other cases they are 4 feet deep. Ford states to "try" to keep the water below the level of the hubs, which amounts to about 15". Aside from possible front axle contamination, my biggest concern would be the electronics on the diesel which are mounted to the frame or floor pan (transmission module, NOx module, etc.) The gas Super Duties don't have these concerns. In the old days, as long as a diesel had air, the engine would run under water. This engine requires electronic control of many things, including the injectors...so it won't. There are also some axle / transmission breathers which run about floor pan high to be concerned about, but these can be easily extended.
Maybe it's due to the twisty frame which GM loves to insult Ford about, but these trucks have excellent wheel articulation. I'd be surprised if a coil sprung power wagon flexed more, at least in the rear. I'm impressed.
Finally, the traction control. I experimented a bit on a slippery rock step. This was the only step which required the rear locker - sort of. The front wheels climbed the step, but the back flexed to the point of one rear wheel basically almost off the ground and severely unloaded. With 4x4 Low engaged, and traction control "off" as much as Ford will allow, the truck could not pull itself up. Turning traction control on allowed the truck to very nearly pull itself up. A little more throttle / finesse probably would have gotten the truck over, but lots of ETC operation glazes the brakes and spews brake dust everywhere. Being able to start in a higher gear manually really adjusts the torque control. Locking the rear end and the loaded wheel bit right in and she went up and over.
When doing some off-road driving, the "off-road" screen for those of you with the LCD message center is kind of fun and informative to watch. It's nice to see how far your wheels are turned left or right when spinning in ruts or what crazy angle your truck is on. Howie Long could probably document the exact up / down / left / right slope angle a Super Duty needs to be on in order for the tailgate not to open. I never had an reason to open the tailgate while in these crazy angles, of course.
Overall, very impressed. It's not as good as my old Range Rover, but I would say more talented off road than ALL other Ford vehicles except the Raptor.

I have an issue with my 7.3.... the truck will not start if it sits overnight without being plugged in, even in 65 degree weather. It starts and runs with a rough idle for about 10 seconds after its been plugged in for an hour, after the rough idle is gone it runs great .. it will Stat back up as long as the truck is warm (70+).... I've replaced the batteries, glow plugs, starter (it was going bad) and fuel filter. .. also replaced the gpr today. ....

My truck usually starts up great, but every so often it takes 3 to 4 long cranks before it will start. By long cranks I mean more than 4 or 5 seconds of turnover. Seems to be no real rhyme or reason to this. It does it engine cold or hot. I have iPhone engine monitor app and numbers seem fine. BTW it's a 2005.

I drove the truck Sunday to 3 different places, parked it around 3:00 pm. Went to take it to work the next morning and it just cranked with no start. I pulled the codes as I have an edge insight. I got a P2614 code so I figured it was the cam sensor. We after some reading to what everyone had to say I checked to see if I had RPM when I got home and I did so that put me back to having no clue. I took as many readings as I could to see if any one might see something that I am not.
ICP psi 1280 cranking 23 key on
IPR 41% cranking 14 key on
IPW ms 0.00 cranking and key on
Fuel Pressure 63.1 cranking
ICP voltage 1.6 cranking .3 key on
Mass Air flow 8.3-10.7 cranking 0.00 key on
Engine RPM 166-205 cranking
FICM 47.0-47.5

So I have a 03 f250 6.0 with 285,000 miles, when I shut the truck off and let it sit for like 20 mins and go to restart it, it cranks then just stops and I hear what I think to be the starter still turning till I let off the key. It'll do this for a while sometimes. So what do y'all think it could be? P.s I know it's very bad for the truck, but I have ran out of fuel about 9 times on the stock pump because my fuel gauge is off, and after the most recent breakdown is about the time it started.
