False ICP and IPV readings

Hey guys, Iíve read several dozens of threads over the last few days. Nothing that Iíve found is really relevant to my symptoms. So here goes...

After replacing the front cover, LPOP, bed plate seals, and getting it all back together I couldnít get my truck to start. I ended up holding the oil filter drain valve closed and filling the HPOP reservoir through the filter stand pipe. When the oil level equalized i installed the filter and gave it one last opportunity to start. After a few seconds of cranking it started! It ran for a few seconds then died. It has done this now multiple times with the longest run time about 45 seconds. It would just idle down and die like you turned the fuel off, not like turning the key off. Hope that makes sense. A few times while running the ICP would go to 550-600 then surge back up to 1400-1500 instead of dying. Then my batteries went dead so I charged them and now it will not start. Now ICP climbs to 1400-1500 and ICPv goes to 1.63 IPR duty cycle at 39.1 but it just cranks without starting. All of the numbers are right as far as I can tell. Iím stumped .

Would this be a fuel problem, electrical problem, or an oil pressure problem? After my batteries charge a little I can post video of the scan gauge if needed.

Re: False ICP and IPV readings

When you can, please post (cranking) Sync, FICM Sync, FICM LPower, FICM MPower, rpms when you get a chance.

It wouldnít allow a video so here are screen shots of different times in the video. Earlier today I did have sync. I changed that to ICP so Iím not sure when the sync stopped.

If that first pid is ficm sync it’s staying at 0. That is likey your issue. Check for proper cam and crank signals.

Re: False ICP and IPV readings

Yeah, we need to see both Cam/Crank sync and FICM sync. Also need to see rpms when cranking (especially when there is some doubt about sync).

9.5V LPower when cranking is low.

Re: False ICP and IPV readings

SYC is typically Cam/Crank sync and FSN is FICM Sync in scangauge language. We just need to know for sure!

Re: False ICP and IPV readings

This morning the ficm sync was a 1 and thatís when it would start and run. Now itís a zero and wonít fire up. I canít find the scan gauge parameters for the cam/crank sync. I will charge the batteries overnight and report back tomorrow.

Is it possible that the low batteries would cause it to not have the ficm sync and the low ficm logic voltage?

P.S. My wife just reminded me that before I repaired the oil leak and all the other stuff it was occasionally hard or long start. And actually died once while idling. Maybe that will help, I dont know.

Ok. I got it programmed and hereís some pictures. First one is while cranking. Second one it started and ran for a good 20 seconds. Third and fourth are while running after a third start. I wish I could post the videos. Itís doing about 300-400 rpm while cranking.
