Did a lot of chasing but found more info about relay, Seems some models are different depending on engine? 5.7 hemi
anyrate found a video with the same style fuse box.
I could not hear the board relay click but on C10 W18 and orange with red.
meter showed power up for 2 seconds with key to on.

best video I found with the same TPIM. does not get to fuel relay till about the 15 minute mark.

I dropped tank today but having a bitch of time to get wire clips off. I'll try again in morning. I work a rotation shift so if I can't get it off in morning be at least 2/7/24 before I can work on it again.

I did manage to break the plastic clip for fuel line that come up to the gas filler. Recir tube? 55398361aa order it and a fuel pump.

You should be able to hear the fuel pump prime at initial key on. (if its quiet enough when you try....) If pouring gas down the TB doesn't at least get it to fire once or twice, or even backfire, I would be looking at a spark problem.

Hi, welcome to the forum.

So a short to ground at the throttle body caused your fuel pump to not run?

...or was your truck cranking over but not starting... and you found the faulty (reason why she wouldn't start) to be because of a short to ground at the throttle body?

Was it a loose pin, an abraded wire harness, something out of position that crushed a bundle of wires?
How do you think it happened?
