With key in on position, short out B+ and Fp... this should supply power to the pump to check pressure or operation or whatever while car is off.
I had a hell of a time figuring out a problem with mine once... heres a couple things i remember off the top of my head. EFI main relay should make an operation noise when key is turned on... check first.. then see what your power is at the EFI fuse... i think thats what its called. Something else to check.. does check engine light come on when key turned to on? if not, theres a couple things it could be. That was what my problem was, ended up being a loose (number 15?) fuse on driver side kick panel. Wedged some paper in there to fix a problem i was trying to solve for two weeks... lol |
