The plug color is on the documents just abbreviated... C1 (BLU) = blue... C2 (GRY) = grey... C3 (NAT) = naturalI am not sure which of the three are C1 C2 C3, etc
Maybe you can match color wire from pin 1 on each diagram
I would assume far left is C1 and far right would be C3
Thanks for the quick response!Attached are a couple of pages from the service manual for the fuel pump wiring.
IF the trigger wire tests good, I assume that the pcm is the only thing left that could be the source of the problem, correct?
What would be the correct way to check the ground being commanded @ C2 Pin #3 when the key is turned to the ON position?
Anyone have input on my questions above? :undecidedSo, to check continuity between C2 Pin#3 and relay...do I simply check it between noted pin and top left contact of relay socket (as viewed from driver side fender, as shown in fuse box diagram above)?
:woohoo:I am not 100% sure if this is what the OP was requesting but I think it may be.
Also, these are for a 2003, not a 2004. Am not sure if anything is different so please be aware.
Sorry if some of the images were skewed. Its difficult to get thick manuals to sit flat on the scanner and I would rather not mash the spine flat.
