FICM Problem!! Please Help

Hi, i just did an egr delete on a truck. It went real smooth. When i got all done and went to start it would not fire.

My scanner is showing codes p1378 and p1000.

The ficm logic voltage is at min. 10. which i believe is the problem.

The whole job went so smooth i can't think of what it could be.

It is an 06 6.0L. I have checked the logic fuss under the hood. And the ficm relay.

Any suggestions would be awesome. I am assuming it must be a wire rub or something like that, or a fuss i didn't check maybe. Maybe it's plug i forgot to plug back in or a ground wire not on.

Really driving me crazy though.

Thanks a ton in advance.

did you pull the intake manifold, if so you may have forgotten the ground that goes on the very back stud on the drivers side? or maybe batteries were too low on power, cranking on low batteries kills the ficm

I didn't pull the intake, just loosened it. I checked that ground 10 times I think. Are there any grounds our wires under the batteries? I was kind of sitting in the holes with the batteries out. Anything under there?

Check your connectors on the FICM. Are you using a scanner that can read the data stream? to check FICM voltages. If you are using a code reader it may not pull all the codes.

Weird thing is I never unhooked it but I will check them. I am using an ae scan tool so it is reading all data. My logic voltage is at min. 10.

Are you seeing FICM voltage above 45VDC on one line? I have a Snap On scanner and there is a few lines of voltages you can read. I'm thinking you have a problem with the FICM, IDK for sure.

I figured it out. Took a little break and went back to it. I took the batteries out and looked around. I found a connector on the drivers side firewall not pushed all the way in. It must have been loose before and when I was in the engine I pulled on it just enough to make it not start. Lesson learned, Always check all connections, even the ones you don't touch before you panic at a no start.

Thanks for the help guys
