Hey guys, was driving my car earlier and it just randomly shut off while driving for about 15 min (right after I just finished detailing it, of course). Pulled off into a parking lot to diagnose. Found the fuel pump wasn't priming. Replaced relay b/c it terminals were gross and needed to be replaced regardless of the issue. Anyways, the fuel pump wasn't turning on at all..no priming or anything. There are 12v going to the pump, and the pump will only turn on if I ground it to an external source ( if I understand correctly the pump circuit is ground switched, correct? and it has two ground circuits for the pump).
So I was wondering if someone could point me in the right direction as to where to find the ground issue i.e. which pin on the ECU it is, which ground circuit to check, etc. Sorry i'm just trying to get this fixed ASAP...don't like my car being in a random parking lot for very long!
Thanks in advance
