No start cold
New to diesels but I have watched A LOT of youtube sobasically I'm an expert (note to sarcasm). I have a 2007 F250 with 160k miles that I have had since 135K.Supposedly, it was "bullet proofed"advertised to be EGR delete and head gaskets replaced with studs.Turns out it also had stc, dummy plugs andIPR.
I replaced injectors at about 145k due to runningrough. Great success.
155k I started getting a long start when hot.
157kish, I had a no start that was the ICP
160k is where I'm at now. The truck started running rough and then not at all.I unplugged the ICP, and it ran fine.THIS DOESN'T MAKE SENSE BECAUSE THE ICP ISNEW.So I decided to change out commonparts for long start when hot and replace the ICP again to fix bothproblems.as mentioned before, the STChad already been changed but was loose.I hope this is the cause of the long start when hot.I put in new STC, dummy plugs, stand pipes,IPR, ICP and did a air compressor check for leaks.Everything went swimmingly but I have a no startwhich is very frustrating to say the least.I unplugged the ICP and still no start.
My xguage shows as below. 0 ICP, 85 IPR, 48 FICM, 0.23 IVC, 1 SYNC.Pressure check shows no leaks and HPOP is inproper position (I double checked
When I unplug the ICP it shows 1500 ICP, 69 IPR, 48 FICM,0.00IVC
Wiring harnesses looks good.
I have base oil pressure and I'm confident the HPOP isinstalled appropriately and this year model says the pump almost never goes badso I'm pretty sure I am actually getting pressure to the injectors so I don'tbelieve the ICP of zero on my xguage. But when I unplug the ICP sensor, ICP goes to 1500 but the ICV goes tozero and still no start.Is that causedby the FICM?
What am I missing?
Thanks in advance for your help. Diesel Tech Ron didn't have a video for thisone unfortunately.
