Hi, my name is ***** ***** the fuel pump removed, how many prongs have power, when cranking?
yes, probe the pins in the socket and see if 2 of the pins have power, when cranking,Tim
that scematic shows pins 1,2 3 and 5????
No, pin 5 should be grounded, from the PCM, not powered, it grounds that pin to activate the relay and send power to the fuel pump, but also pin 2 should not have power on it????
the pins 1 and 3 have power, then when you turn the key on, pin 5 gets a ground from the PCM, which then activats the relay and it sends power to the fuel pump through pin 2, but pin 2 nshould not have power with the relay removed, at any time
ok, so with the relay installed, and the ke on, then you have power on the pin 2?
then the fuel pump should run, the relay is working the way its suppose too??? what did you jumper to get the fuel pump to run? the pins 1 and 2?
3 and five are the coil controls for the relay, so you most likely dont have a ground on the pin 5, can you check the pin five for a ground, with the key on and relay out?
let me know,Tim
did you check this pin for a ground?
one of them was for the Pin 5 wire, wasnt it?
pin 2 that goes out to the pump???
