Help with fuel pump and relay Power but no Pumping
ok so car ran just fine 2 days ago. got new chips from enthalpy today and went to start it and nothing.
traced it back to the fuel pump not working. call enthalpy, they said the tune has nothing to do with the fuel pump. put old chips back in, nothing!
so, i checked the fuse, its good
checked the power going to the fuse, its there
checked the ecu fuel pump relay pin 104, power there too
checked the 2 wire harness on top of the fuel pump "hatch" NOTHING
checked the 4 wire plug and with the multi meter on the red and black wire in that plug i have power at the red wire...
pulled the pumped and checked it, its good, cycled just fine
so what am i missing here?
i have a back up pump and it works but whtas the point of putting it in if the old pump works out of the car.
where is the fuel pump relay located? i read in the FSM thats its by the fuse panel under the drive side kick panel...does anyone have a pic of it? there are a few down there and im not sure which is which.
car is a 98 with redtop in it. have had the swap done for 5 years now and never had this problem
