Hard To Start

First of all let me start by saying thanks to everyone on here for all the patience and help.

I replaced the IPC sensor and pigtail sunday afternoon. Man what a butt whip that was. After I put everything back together and tried to start the truck it took 4 tries to start it. It would turn over just not start . It never did this before I change that part out. It would start on first try every time.

My question is this: I had to take the FICM off and completely unplug it. Does it take time for that module to reset it self or is there something I need to do? Once the truck starts it runs better than it did when I bought it.

Once again thanks for the help.

Once any component in the high pressure system is removed, air is introduced into the system.

Air is more compressable than oil, so the high pressure pump must compress all this air before the system pressure rises enough to allow the engine to start.

It typically takes quite a bit of cranking to make an engine start after any high pressure system repair. It will also run rough, and generate no power until the air is purged. I would suggest once you get it started, perform several wide open throttle accelerations - 10 to 15 of them from 0mph to 60mph or so - to help purge the air.
