Buddies truck wont start, New FICM.........

[cRaZy8]

He has had issues with cold starts since january. Progressively gotten worse.
Here are the facts:

-2006 F350 Dually
-Bone stock except air filter
-Hard starts turned into no start yesterday (60* outside)
-FICM voltage 19V key on, 14.8V cranking
-Batteries less than two months old
-Last trip to dealership in January, replaced fuel tank, fuel conditioner module (didnt fix hard starts obviously)
-Installed Swamps 58V FICM this morning (I helped him)
-No start, cranks hard, 57V key on, barely drops during cranking
-Puffs white/gray normal smoke color while cranking
-Injectors buzz
-Fuel pump runs, fuel in filter on motor
-Shows oil pressure while cranking (stock gauge)

We put the FICM in thinking that was the issue, apparently not.

Any ideas???

ICP issue?

Glow plug module or injectors. Often when the FICM goes, its starts taking injectors with it.

New FICM? new FICM's need to be programmed

[cRaZy8]

His best guess was that the injectors are failing. Seems like a common trend.

Swamps says their FICM's do not need programming.

What about the HPOP STC? Could that have finally let go? He drove to a job in the morning, truck sat for 9-10 hrs, then would not restart.

HPOP, STC, or branch tube failure would be a no-start when the engine is hot.

Back to the FICM -- my FICM was bad so I replaced it. Ran even worse afterwards. More troubleshooting led to the replacement of all 8 injectors.

Ya, I missed that it was a swamps FICM.

Mine did similar a few weeks ago and it was the STC.

He gettin sick of his truck. Nothing but problems the last 6 months. Over $8k in repairs. None of which under warranty.

He is so ready to go get a Cummins. Only problem is, he is a welder/fabricator. And his truck has a quick change hydraulic bed system with all his gear set up for the Ford.

He had it towed to the dealer today. He says they should have an answer by monday around noon.



Side note- we had a new boat delivery today, the hauler was an independant guy. 2002 F350 Super Crew Dually, 7.3L, tuner, studs, exhaust, intake- 315,000 miles. One fuel pump, and one HPOP. All highway towing miles. Tows a tri axle boat trailer up to 20,000#. WHY DID THEY EVER STOP MAKING THAT MOTOR?
