Ford 7.3L Power Stroke (1999-2003) :: Crank Continually But Wouldn't Turn Over / Waste Gate Fail Code
Jun 21, 2015
I have a 2001 7.3 that recently had a throttle position sensor issue I replaced the sensor 4 days ago and my truck ran like new. Until last night I shut my truck off and went to start it up a few seconds later and it would crank continually but wouldn't turn over so I went for the obvious and replaced the cam sensor but that didn't change anything. My scanner is throwing a waste gate fail code.

I understand how the waste gate is supposed to work at high rpms / boost.
I believe that as long as I keep the max boost down, that I can run with the waste gate plugged in order to goose the power a little in the 2000-28000 RPM range. Since the truck is stock and there's no intention of running higher RPMs, it seems like plugging the waste gate is a good idea. I just want to make sure that I'm not missing something.
It appears that the wast gate also opens when at idle and possibly when you let off the throttle. Are these important functions of the waste gate as well?
Here's a chart showing waste gate operation...

So the PO tells me he was flying down the highway and went to cancel his cruise control and it wouldn't turn off. He claims he made it to the shoulder of the highway and killed the ignition. When he restarted the truck is was turned off and it hasn't been used since. I tried to use it yesterday but couldn't get it to work?
So I do the search and find out that the deactivation switch is most likely the issue. I just picked up a new one today and was curious if it is just a R & R thing or if it needs to be bleed off or something? Is there a need to test it or just change it out? Sound like something that would cause these issues?

New to the forums, not new to fords. 1999 F350 7.3L Diesel. This has been a work truck and has seen multiple devices in and out over the years. I removed the last crap for GPS tracking etc from the last owners. The truck has worked well for a long time since until...
I'm moving slowly to a different state and so the truck got parked for 2 months. went to start it and nothing. the dash comes on and all the lights come on but when you turn the key to start the power drops and nothing.
Testing so far:
replaced the fender Solenoid
tested the starter motor and solenoid -passed
replaced the ignition switch
tested continuity of the hot and ground wires to the fender and starter and everything passed
When I shorted across the fender solenoid the starter works and tries to start the truck (unsuccessfully so far)
So the wire that goes to the fender solenoid is not working and where to trace it to and what needs to be fixed. Is there a relay or fuse besides number 30 that is in the way? where does the magical wire go so i can check its continuity?
I am stuck 800 miles from where i need to be and I am stuck here. I don't have the cash to get a mechanic and my mechanic friends are stumped. I do have a Snapon modus tester, what to do with it.
FYI the batteries are new and fully charged.

Alright so I have a 99 7.3l. One day I went to start my truck and when I turn the key to the on position all is normal and then when I turn it all the way to crank it nothing happens. I hear a relay click ann thed that's it. Me and a buddy of mine spent quite some time on going through the entire truck. The starter was replaced, the neutral safety switch was replaced and the ignition switch was replaced yet the problem is still there. We then discovered that fuse #20 under the dash keeps blowing with every turn of the key. The manual states that this fuse is a starter motor relay coil PCM ( gasoline only). So if it's gas only why is it even in there. Let me just say that I can jump the fender mounted relay and the truck starts.

Okay, I am having issues with a 1999 F250 XLT 7.3 with diablo programmer. I have searched and searched and have tried everything we could think of and it is a no go. The truck will crank, hesitate to start, start and die, other times it will only crank and not run at all. We can make it stay running by hitting the accelerator. The only code we were getting was the cps code, but that is suspected to be because of the excessive cranking and no start times. Previous to this issue getting this serious it would stall randomly, at idle, going down the road at constant speed, slowing down, or accelerating. We now have code P0231.
Through this we have tried:
IDM
(loaner) ECM
removing Diablo
3 CPS
shaving down CPS
Shimming CPS
IPR
Fuel pump
relay
fuel pump fuse

I have a 2006 Volkswagon Jetta GLI and when the check engine light went on I took it to my local car guy. He said the Turbo Waste Gate isn't closing properly and I should take it to the dealer to see if it can be repaired or if it has to be replaced. He told me could replace it if that's what's needed but he can't repair it but I can still drive it probably just for a few months before it needs to be fixed.

I have a 2003 2wd F250 with the 7.3l. I replaced the stock tail gate with an aftermarket 5th wheel tailgate. Seems to work good but a couple of times the bottom of the tail gate where the hinge connects pops out when on dirt roads. I know it is probably from the shaking and rattling that the road causes but any way to prevent that from happening? I know most will say stay off the dirt roads but until they pave the road to the dunes camping spot I'm stuck with going down it.

A month ago I got into my truck in the morning and when I turned the key to Run everything lit up like normal and after the glow plugs warmed up, I turned the key and there was about a two second delay between me turning the key and the engine cranking over.
The next couple times I tried starting the truck that same morning I had to try to start it a couple times because it wouldn't try to crank over the first couple times but it would always eventually start.
It's been continuing to give me problems but never stopped running once it was started and then this morning I tried starting it for 45 minutes with no luck.
What I have tried so far is:
Resetting batteries
Jumping the truck
Checked to see if the starter is getting power. ( I put wire testers on it while someone else started and I didn't get a good reading even when it did start. New starter was put in 9 months ago.)
I also made sure wire going to starter wasn't corroded
Battery terminals are also not corroded
Checked fuses
Tried starting truck with fan clutch disconnected
Cussing at it
Tapping starter with a hammer while trying to start it
Also, everything sounds perfectly normal when I turn the key, it just doesn't even try to turn over.

2002 f250 7.3l diesel...
I got a new radiator and the tranny fluid was the worst the mechanic had ever seen. He serviced it and warned me that it might not be long for this world. I broke my flexplate and so I had to pull the tranny, and I decided to throw a new torque converter in because it was giving g me symptoms like a broken sprag( it wouldn't rev up or do a brake stand in gear, therefore slow takeoffs).
I was recommended to replace the tranny, I decided I could do the job again down the road if I needed to. About two thousand miles down the road I had a hard shift going from overdrive down to get up a hill and about 10 miles later the truck started slowing down....I couldn't give it enough pedal to keep it going and the engine sounded rough.
I pulled over and checked fluids and everything was fine, truck idled fine, bright red tranny fluid not burnt at all. Pulled on to the road again and it pulled fine until about 40 mph and it wouldn't go any faster. I got it towed home and ordered up a tranny from Ford figuring it must be toast, but I thought I'd throw it out to the forum to see if there is any other troubleshooting I can do before I install the new one in case it is some other problem or some electrical harness or something, or if that is a pretty standard reaction to a fried tranny.
Engine runs good at idle, shifts perfectly to drive and reverse, drives forward and back(I'm very hesitant to drive it out of the driveway in case I can't get it back in). Only happened two times before I decided to tow it. Temps looked fine on the gauges, fluid was a little overfilled in the tranny, but again, not hot or burnt.

Just recently i have noticed my truck acting up. the other day at about 10 to 20 mph i made a 90 degree turn and noticed my steering wheel wouldn't return but i had to bring it back. than this morning the same thing happened. I made a 90 degree left hand turn and it happened again. the truck wanted to keep going left but i kept turning right. it almost feels like my power steering pump is going out. The pump was changed about 4 years 90k miles ago. I'm curious to see what others have to say. What could it be????

So yet another crank no start. Truck is an 03 55k miles The guy I bought the truck off of told me the turbo had been reconditioned about 1000 miles ago. Drove the truck another 1000 miles or so and now having issues. I went to start truck up and noticed it took awhile longer than normal to start up and when it did finally kick over, truck and no power at all. Would idle a bit rough sounded like no turbo spool at all when given throttle. Shut the truck off right and hooked up scangauge to it went to start it and nothing.
Did throw p2285 code ICP low circuit
Values read on scangauge are as follows:
FICM Main Power 48.0V
FICM Logic Power 10-8V
FICM sync is good
ICP Pressure 1540psi on crank
IPR duty cycle 14.8% Key on engine off/48.8% while cranking
At a bit of a loss as to where to look next, would really like to troubleshoot down to the right fix instead of just throwing parts at it. Have read after sitting the turbos tend to stick and need cleaned or replaced. After being cleaned only a few thousand miles could it be stuck again? Seems like I have spark, fuel, oil just acts like its not getting any air.

Iam looking at a 2000 7.3 Powerstroke that has some problems first it is hard to start cranks like it has a dead cyl. Second after starting it has no power not even enough to move. At first it would only run if held wide open but once it warmed up it would idle and rev and move but barely still had a miss. The weird thing is it did not smoke blue-black or white also no strong smell of diesel and no smell of oil at all. The truck has 230ish miles and there are no maintenance records.air filter was new.

I have a e99 f350 7.3 all stock. I have no power. The truck will crank for about 15-20sec before it'll turn over. I just purchased the*AE*but am fairly new to understanding it all. In idle its a little rough and when I drive I can only stay in the neighborhood because of fear of getting rearended due to very slow acceleration. Whats weird is that when i have no power while i am driving ill keep the pedal down throw it in nuetral and my rpms and*icp*pressure jump up right away. Things I've replaced:
Icp*sensor
Fuel pump
Pcm
Tps
Cps
Ipr
Dropped tanked and cleaned screens
When cranking my*icp*pressure climbs slowly to right under 500. I dont know what else to do ive been working on this truck dor two months some days 13hs straight, I am feeling defeated. Codes p1249 1211 1209....

I have an intermittent security system issue. I sometimes get a dotted line in odometer and rapidly flashing theft light.
Crank no start. After a time, the theft light flashes a code of 1 then 4. Research gives me the result that PCM did not power up.
Have pulled gauges. Fixed known cold solder joint issue. Checked all connectors and reinstalled. Truck starts fine about 7/10 tries.
I have replaced battery terminals. Removed cleaned and replaced all firewall grounds. Checked harness connection blocks and PCM connector. Made sure all under hood fuses and relays working.
Currently sitting in a parking lot waiting for it to decide to start again. Only one chipped key. Where to look next? 1999 F150 xlt 6 cylinder.

I have a 1999 7.3 super duty that won't crank when the key is turned. All lights work, power windows and mirrors work but after the WTS light goes out... Nothing...now I do have a slight leak in the roof and a little water does get in the cab. I opened my door the other day and it smelled like an electrical fire had occurred. I checked under the hood and the same smell, if not a little stronger. I pulled my fuse box and GEM tonight. Once I got away from the truck, I expected them to smell like the electrical fire smell, but they didn't. Now I did try cranking the engine over by jumping the starter relay before tearing the fuse panel out, and I got it to crank, but not strong at all. The batteries are good.

Started truck 3 times in 30 min. no issues with truck before tonight nice well cared for truck. Went to get a pack of buns at store came out --NO CRANK--all lights are on dash, etc, new starter a month ago, relay changed out in fuse panel just to see if there was a change. Bought two new Motorcraft batteries installed , NO CHANGE, so is it natural safety, key switch, electrical ignition switch, solenoid on starter, is there a solenoid between key and starter?

On the way to work, the truck seemed to have a miss at idle and the CE light came on. Long crank to start leaving work, and truck starts losing power and eventually died. No smoke while it was losing power. Towed it home and checked the fuel pump and lines for blockage and found nothing.
2003 7.3 F-250 430K miles
strong cranking but no start no smoke out exhaust
Oil changed recently
IPR changed
Both UVCH gaskets and pigtails have been repaired.
ICP sensor and harness changed, also disconnected no change in cranking.
fuel filter changed today (no oil in bowl)
3/4 tank of fuel
dash gauge for lpop goes up to normal range during cranking and oil light turns off.
WTS light comes on and turns off as normal
tach gauge moves up between 100-200 during cranking
fuel pump turns on and pressurizes system like normal and turns off.
Ordered AE for the truck, and it directed me to the passenger side bank high open. Fixed the harness on that side and still nothing.
Sent off the IDM and it passed with flying colors
So now i'm leaning towards the HPOP, but would hate to fork over the cash for it and still not get anywhere. I'm going to take the valve covers back off and check the discharge ports for the injectors tomorrow.

I have an 02 f250 230,000, first 7.3. I've owned it since Oct and put less than 6,000 miles on it. I have another cold crank no start. New glow plugs and Glow plug relay last weekend. Worked fine that weekend. It sat all week, then crank no start fri night, it was like 70 degrees for the high that day. Plugged it in over night and it started. Did not fire right up cranked it for a couple seconds. I drove it all day, started every time. Valve covers have 5,000 miles on them. Fuel Filter heater fuse not blown. But don't know how to check it for sure. And don't know where to go with it from here. Getting frustrated with crank no starts. No troubles found.

I got a 2000 7.3l with 400,000 miles on it that decided to just not start anymore after I parked it for a couple days. Its always been a hard starter due to needing glow plugs but I can deal with that. it doesn't even try to fire anymore. I replaced the CPS (my tack bounces when cranking). The ICP has oil in the plug so I just unplugged it for now till I replace it.
I pulled the IPR and cleaned it really good and bench tested it with 12 volts and could here it clicking so I put it back in. I can get under the drivers door with the key on and hear the fuel pump running. I gain oil pressure on my dash gauge when cranking. I check all my fuses. my WTS light comes on . I just don't have any fancy scan tools to make this easier. Also just cause I was feeling lucky I just went out and bought 2 new batteries for it yesterday so we are good there.

I have a 1997 F350 7.3 with standard xmission. Have not messed with it since Oct of last year. Then it would crank but no start. Now when I turn the key there is no wts or nothing the gauges move, and tach moves when cranking, but nothing else.
The cam and crank pos sensors have been changed. The high pressure sensors changed. Now when I hook it to the AE it says cannot connect to truck. Where I need to start? Have checked all fuses that I know about.
