Ford 6.0L Power Stroke Diesel :: 2003 - At Signal In Gear Surged - ICP Volts?
Mar 21, 2016
03 f350 srw. Today and a few times in the last couple weeks when sitting at a light with truck in gear it has surged a little bit. Not hard enough to make me push the brake pedal harder but noticeable climb and then fall of a couple hundred rpms. I remember hearing or reading of somebody else with the same issue and it ended up being a bad ICP. Checked it koeo when I got home and it was at .35 volts(scan gauge II). I don't recall the right number but that seems higher then what I remember it should be. What else other then pulling the plug and checking for oil should I be looking at? I replaced #5 and #6 injectors about a month ago, and everything seems to be good with that. I don't think the two are related but I'm no expert.

Another thread on here about Time for Batteries got me to thinking about mine and whether I should change them based upon time.
They have been in the truck 4 years and 6 months or so. I was reading some older threads recommending changing around the 3 year mark to prevent damage to the FICM.
I don't drive the truck everyday and sometimes it sits for 3 weeks or so. I noticed 2 days ago when I took it to work, I got one of the slowest cranks I've ever gotten. But after it's started and the glow plugs turn off, I get ~ 14.1 - 13.4 or so volts.
FICM voltage never drops below 47 and usually runs between 47.5 and 48.5 volts.
I'm not sure what size alternator is on there. Plus it's a single. I also have the upgraded cables that Mr. Jack recommended for extra battery life. I guess it's time for batteries though?

I never tested a ficm before and just want to make sure before getting it repaired. I had 48.5 volts with the key on and while cranking went to 49.6 volts. While holding it on for a second time it went to 30 volts and jumping around while cranking and then to 49.5 and the truck started and it was at 48.5. One other thing is my injectors are chattering when the key is on but not all the time. (not sure if this is normal). If the ficm is bad and someone recommend a ficm repair shop. This truck is non stop with repairs I need to start working on it myself.

I am having a charging system issue. The alternator is making barley over 12 volts. With KOEO the battery light on the instrument cluster does not come on. I have already replaced both batteries and the alternator -before i noticed the battery light is not coming on.

Plugged in scanner while I was still running it, said egr volts were weak, i just cleaned it yesterday.. and earlier today reset the check engine light once but then drove about 30 miles with no reoccurrence of light. Now i pulled over, shut off truck unplugged egr and reconnected. Went back to start my truck and nothing at all. Its like I am trying to start it in park.....been here for about 3 hrs now I've checked fuses nothing is blown. I am just sitting here freezing trying to fig out anything i can on line.......

2003 6.0 psd owned two years driven 2 months due to money thrown prior to forums and scangauge 2. Bought truck in chicago drove home. Oil in coolant. Did egr delete oil cooler all gaskets orings etc. New oil filters motorcraft fuel filters .new rad fluod wix trtmnt. Truck started right up. Still had same intermitantstudder as always when cold. Always exp those sysyems until hot then here and there until parked then hot no start or hard long start when hot. Knew something was wrong and waited for it to come to a head well it did in may.
I was driving coming up to a stop sign and truck died like i shut key off. Refired once off ether. Lasted 3 seconds died no restart period didnt even want to just crank crank crank.
ok towed truck i thought it was injector orings. Changed them still nothing . New icp. New cpm. Now have icp of 66 to 120psi cranking.ipr 14.40 koeo up to 84 when cranking. Ive unplugged just get eratic reading ipr stays same. Checked ficm 47to47.5 cranking and koeo. No codes beside for my egr delete and when i unplugged icp. I've been tinkering on this truck for a couple years now still lost bit getting better. I now have driver valve cover off . Its a 2003 .

After installing new glow plugs, glow plug relay, and valve cover gaskets my 2000 7.3 is throwing the 1395 code. Glow plug monitor Bank 1. Any input as to cause? Checked all connections to relay. All tight. Read something about fusible link. Where that is located? One side of relay reads 0 volts.

The brief information:
1. Stuck/non moving in traffic on the freeway for roughly 1 1/2. During that time the AC was running, but once I noticed my "battery light" on the dash turn on, I turned everything off.
2. Since then while on my way home from work the voltage meter only showed barely 12 volts at full throttle.
3. I charged my battteries, and started it up today to go into work. While going to work the voltage meter showed 14 at its high point, but shortly there after it dropped back down to 12. At which time the battery light came back on.
New battery or alternator?

After doing some hunting/wheeling with my son, got back to town and 2003 Excursion w/ ~145K miles would not budge in any gear. No codes with Scangage. After 30 minutes I finally thought to rev it up and it shifted hard into gear, and drove normal home. What do do now?

On cruise control, engine went dead immediately after passing gear kicked in. After 2 days on the side of the road got a pull to the house. Then after having a charger on it over night the electric seems to be messed up. Switched on, the dash lights light full strength for a fraction of a second before appearing as thought the battery is real low. Also the doorlocks act crazy. I think maybe I blew out the BB on the high oil pressure pump.

Started truck, used windshield washer and noticed High Beam Indicator was lit on dash. Headlight switch not on. Drove to Ford dealer, turned off truck, high beams would not shut off. Dealer replaced the Turn Signal/wiper/High beam switch assembly. Dealer had one in stock. Service manager said they have replaced a few of these Switches. So if your High Beams come on without the headlight switch on you cannot turn them off even if you shut off and exit truck. Also the "You left your lights on warning chime" does not sound when you exit truck.

The other day i noticed my turn signal was blinking rapidly. I found that my drivers side bulb was burned out. I am trying to convert most of my lights to LEDs on my truck and figured that I'd replaced the tail lights with LEDs. After replacing both rear taillights with LEDS I still have the rapid blinking turn signal. Whats the deal? is it just the LEDS or what?

Last night I was heading home from a two day race and found that my turn signals wasn't working. the running lights are working and obviously i could feel the brakes working.
well i hooked up some jumpers to a 12v battery and the 7 pin and the lights work. to make 100% sure it works i hooked it up to my neighbors Tacoma. it all worked. well..........
On my last f150 when it was new this happened to me too. it ended up being the turn signal fuse on my truck.
I hooked right back to my truck again and just made sure my plug was all the way in and still nothing so i know its my truck side.
Now my last f150 owners manual had a section to where it told you what fuse is what and where. well i don't even see the f250 fuse box is and don't know which one it is to see if its blown.

All of a sudden, my turn signal won't stop automatically after making a turn. I read that the multi function lever needed to be replaced. I did, and nothing changed... what is wrong since its not the lever assembly itself?

Have a 2003 F350 srw 4x4, 107,000 miles on it. Driving it last night tow/haul light started flashing, hooked up AE got a P0730 Incorrect gear ratio. Truck seem to do ok, cut it off went back out a little while later and the tow/haul didn't flash.... Only issues I've had is when shifting from P to R, it takes a second or two longer than it should and shifts hard when it does but it doesn't do it every time.

Hearing a whistle noise after installing the Recon smoked turn signal lense? The whistle starts between 40 and 50 mph and is the driver side only. I have triple checked the installation and it has the same clearance all the way around as the left side. I sent Recon an email on Jan 5th about this issue and still haven't heard back from them.

I'm looking for a 3156 LED Amber turn signal bulb for the front turn signal, I've looked around haven't found anything! Any success story with this particular bulb, and does it require a load manager when installing?

2004 F250 6.0L!!
An issue I noticed right off the bat was that whenever I had the driver side turn signal on, and the brake was applied, the turn signal freezes.
I took apart the tail light and found a concoction of wires...I posted a diagram illustrating what it looks like.
There is this pesky Red wire that is spliced into the tail light bulb socket wire (specifically the green wire).
There is a trailer brake installed...if this means anything. I've tried disconnecting that with no luck on fixing the issue.
How to further troubleshoot would be great...electrical work is not my forte!

2003 F350 6.0 cc 4x4 with 291k... Not sure if I have a problem or not, it happened at a signal light: The light turned green, I pressed the throttle and started to move. As I pressed more, there was no response. Second later it took off and I have had no more problem. What the cause maybe?

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.
