GEN 1 Fuel pump relay fuse blows when key is inserted.

[dc17172]

The violet wire with a green tracer is the power feed to the fuel pump control module. It also supplies power to the fuel injectors, so if an injector or circuit is shorted that will also blow the fuse. You can split up the circuit for testing purposes by disconnecting C1581 and/or C1010 to isolate the shorted circuit or component.

IT'S FIXED:

FordTechOne, you came in clutch man. Your post was instrumental in getting it fixed. Thank you. There was a short to ground under the coolant reservoir near the C1010 connector. My friend repaired the wiring harness and we were almost good to go. She would almost start but wouldn't quite fire, but she stopped blowing her fuses. My friend grabbed my old FPDM and plugged it in. She fired up and purred. The cheap (Amazon) FPDM failed. OEM for me from here out. Thanks for everyone's help and support.

Nice to see this resolved. There are certain things that you spend the extra money on an apparently that's one of them. Thank you @FordTechOne .

The cheap (Amazon=Chinese crap) FPDM failed.

Great news.

FTFY - Don't buy anything important from Amazon if you can find it anywhere else. Much of the "name brand" stuff is counterfeit.

Over the years on this forum I have seen @FordTechOne come to so many people’s rescue with his uncanny knowledge of the Raptor (all Gen’s) I’m beginning to thing it’s an artificial intelligence because his knowledge is better than Googles. In fact when I have a problem and I Google it, @FordTechOne posts show up. LOL!

Did you happen to take any pictures of the repair? I am curious where the short originated in the harness.

I did not but I will upload the pictures of where it was shorting out on the bracket and and the repaired harness. One of the previous owners butchered it for some reason.

SO true..! Purchased fuel pump for my BMW and it was DOA..never again..saving $100 isnt worth dealing with the drama and time spent.
