I have an early 2004 F250 with 210k miles on it. Over the winter it had hard starts and I suspected the FICM was going out, but put it off do to cost. Last week the truck wouldn't start after sitting for several hours, and a test of the FICM showed it needed to be repaired and that was taken care of.

Installed the FICM today and it started, but as it warmed up it started to miss. I didn't drive it because I was starting to suspect I may also have an issue with my HPO system. The missing became worse and eventually the engine died, and I was in the same crank no start scenario.

I've disconnected the ICP sensor behind the turbo (covered in oil and oil down the driver side of the bell housing), but still no start. I know I probably have a leak somewhere or possibly a bad IPR, but I need to know the next steps. I already plan on replacing the ICP sensor, should I try replacing the IPR as well and see if that fixes the problem? or just start with an air test and plan on probably replacing the HPOP? O-rings on the injecors possibly?

sorry, my scanner only reads codes not the values so I don't know the IPR% or ICP pressure. No codes until I disconnected the ICP sensor (2285). No injector codes in this situation is good right? I'm working on getting a SCANGAUGE II.

Are there any common areas on the early 2004 that the HPO system develops leaks that can be repaired without replacing the HPOP?

 

Hi Chris,

I'm going to send this one down to the 6.0L forum. Lots of knowledgeable folks down there to help you out!

 

you said the Oil Leaked right???

So how is the Oil Leval??????

and where is it leaking from??? was it the ICP Sensor???was the ICP sensor wire pigtail Oil Soaked????

Tripple check ALL FICM Connections are the 3 plugs at FICM In Tight did they Click In????

Id Get the ScanGaugeII going to check the truck out FIRST Before tearing into it as it Might NOT even be HPO Relaited

 

The oil looks like it is coming from the ICP sensor and the harness was soaked so I'm sure I'll be replacing that. The oil level was good, I only have about 2,000 miles on it since I last changed it. It has never been low when changing it either.

No puddles or anything under the truck, just oil on the pigtail and sensor and down the driver side bell housing from there.

 

well the ICP definatly sounds Bad

But if that was the Only Issue then it should have started up when ICP was unplugged

Hope the Bad FICM didnt KILL Injectors since it was Put Off repairing it

So a Couple things here

How are the Batterys and charging system??? a weak charging system will kill the FICM plus if the Batterys are to weak then it wont have enough juice to start

Did you use OEM Oil Filter and OEM Oil Filter CAP?? must be shure on this 110% shure ask if unshure on the Cap
