Ok so my car was running.... i pulled the harness and sodered some wires that were just butspliced. i put the harness back in and now my fuel pump wont prime. i wanted to see what CEL i was throwing so i completed the circut by the ECU and the check light wont flash... im thinkin somethin in the harness would be causeing both these issues. Any help would be greatly apreciated

check the fuel pump fuse and go from there, im sure the relay is still good. double check which wires you soldered and make sure all grounds are grounded.

to my knoledge there isnt a fuse... just the relay which is a shared relay with the main relay

did you d/q the battery before splicing the wires? what wires did you splice?

im sure he disconnected the battery before he did the splicing. thats just common sense. i would test the relays if the starter signal fuse is good. get a multi meter out start at the fuel pump and work your way back to the relays. then test before the relays just to make sure the power is going through the relay. if voltage checks out to the fuel pump then you might have a bad fuel pump motor

Inexperience (not saying that you are) can lead to 'common sense' errors. Sometimes people simply forget to do it.

I also agree, you need to get a multimeter and start from the fuel pump and work your way back.

fml... i hate using the multimeter.... what would affect both the check light and the fuel pump? anything?

reversing/ miss matching wires or a faulty part
