2003 6.0 No Start!! Please help
Hello i have a 2003 f250 6.0 that I have been troubleshooting for the past 2 months. Installed new turbo,oil cooler,hpop,icp,ipr, new Motorcraft fuel filters and oil filter and new orileys fuel pump.after installation the truck started right up. I let it idle for 20min an drove for 1hr.. following morning it started right up. On my hour drive to work it ran perfect. 1 mile before i get there the truck just randomly stalls like someone took my keys out. Tried to start and sounded like starter was bad??? Tested starter and it was bad. Tried restart after new one and nothing. i know starter has nothing to do with it so went straight for icp. Which was soaked in oil an broke.. replaced it and when starting you can hear starter turning and everyother 3sec it trys to fire but will not start..please help, any advice is greatly appreciated.
Icp(new) is reading .3
Ficm all around is 48.1 to 48.6
Fuel pressure 50psi
Ipr (new)when cranking is 84.
HPOP pressure when cranking is 1500 to 2200
Rpms range 178 to 200
Lpop dummy guage on dash goes up quick
NO DTC CODES

What you are describing could also be a logic board issue in your FICM. If you have another 6.0 available to you, I'd suggest installing yours in their truck to see if it fires up. Any Powerstroke-programmed FICM will start and run another other Powerstroke.

When icp was replaced i did pigtail aswell which didnt have oil on it.. ED: can ficm still be bad if reading over 48v all around. Unfortunately i do not have access to any 6.0 :/ if ficm can still be faulty is there any other possible way to find out? Although maybe 6 to 8months ago i resoldered connections which afterwards i was still over 48v and truck ran fine. Maybe a way to check board internally even if over 48v? Cant really afford to purchase one unless i know thats issue as ive put in around 2000$ just in parts in last 2 weeks :/ any ideas

Hi Big Red - Yes, a FICM can still be bad and have good voltage. If you don't have another 6.0 available to you, we can always do a diag for you on it. If it does test bad, the diag fee goes against the cost of the repair or replacement. Sadly, there is no way to test that side of the house without specialty bench equipment or another truck.
You can fill out our intake form to get that process moving if you wanted. We'd only have your module 24 hours regardless of what needed to be done to it.

Hope this helps!

UPDATE....notice a exposed wire on harness by oil housing.. so started checking harness, didnt see any more wires so tryed to start and nothing still.. moved ficm wires around cause they were sitting directly on intake and did not notice any more chaffing.. decided to try and crank once more before i call it a day and what do you know.... started right up.. going to take fiber tape off harness in that area and examine... all pins attached an not bent on ficm so maybe just another shorted wire?

Before you tape it, while it is running, wiggle the wires and plugs to see if you can kill it. That should tell where it is bad.

Yes, deff have enough rpm on crank..DON: i did wiggle the 3 connectors which afterwards started the truck. I did not try to kill it though which would have been good idea to do :/ can say i planned on re taping that whole area of harness rither way though. So far have taped 2 plugs from ficm about 12" down wire which prior to doing i stripped all tape etc to look at wires. Found 2 breaks in wires so far which were on ipr pigtail. 1 more connector to check which is injectors.... out of curiousity, if multiple wires were shorted out around ficm, could that cause low fuel pressure?

Instead of taping the wires, though, consider using the paint on electrical tape since it is rubberized and won't peel. Just put a few light coats on letting it dry between coats and you'll be all set! If you wanted to further protect things, you could then tape up the whole enchilada (Super 33 is what you want there instead of the cheapo stuff) and even put that plastic wire loom stuff over everything.

BTW, if you have low fuel pressure, consider the blue spring kit. It's an easy mod and could well save you from more expensive and even less effective alternatives.

Yes for sure, have new red wire loom covering to match truck lol and im also using 33 and on top of it im using wrap it repair. Its a self fusing silicone tape. Can withstand 500°f plus. Looks very good. An darn. Fuel pressure issue will come later i suppose

BTW, bad voltage regulators on alternators are the #1 reason for bad logic boards on FICM's. Regardless of the path you go, I'd STRONGLY suggest bench testing that alternator. If you do need another one, stay away from the remans at an absolute minimum. If you can at all do it and it IS bad, consider upgrading to a properly sized one.
