Chevrolet Repair Questions? Ask a Mechanic for Answers ASAP
Hello, my name is***** do you know the fuel pump keeps running?
Are you 100% sure you are removing the fuel pump relay? Have you tried to remove each fuse and relay one by one to see if anything else shuts it off?
Because if it really is fuel pump that would mean the gray wire that goes between fuel pump and fuel pump relay has shorted to power which is unlikely.
The ECM B fuse powers relay then it powers the fuel pump.
Here is a picture of the fuel pump relay so you can be sure it is the right one. If removing fuel pump relay doesn't help disconnect gray wire at pin A3 fusebox connector to verify pump shuts off, if not replace wire between pump and fuse box. If it does shut off the fuse box has internally shorted and needs to be replaced. Let me know if you have more questions or if there is anything else I can do to help .Thanks.
I do not see anything in wiring that shows a common wire. Lets start with wiper problem and see where it leads. At wiper motor black wire should have ground, yellow should have power, and purple should have power with wiper motor in high position. Let me know what you find, thanks.
Sorry about that. You need to remove the connector from fuse box then pin A3 is terminal on connector going to fuse box with a gray wire. If pump shuts off when disconnecting gray wire you know the fuse box has internally shorted, if not the wire has shorted. I think the problem is more likely the fuse box then wiring. Let me know how it goes or if you run into more questions, thanks again and sorry about confusion.
