First time builder, auto-electronics challenged
I'm mid-build on my mk4 roadster with crate coyote, irs, almost no electronics.
Can't get my head around the exterior fuel pump wiring and how it communicates with the computer.
I've tried to follow the manuals exactly and thought all wires/harnesses were installed correctly.
Big day today to fire engine up - ......no go. The external fuel pump was not receiving power . wires checked with meter
and no power going to fuel pump
. Jumped wire to ensure pump worked and it did, but engine still did not fire (thinking computer didn't allow start due to jumping of wires). It turns over but no fire. Fuel pressure reg shows 50-60 lbs.

Any info on this would be appreciated. ]]> Mike DeLisle https://v1.thefactoryfiveforum.com/entry.php?1294-wiring-nightmare
