Re: [DML] Re: electrical problems relating to fuel pump

["DMC Joe" <dmcjoe@xxxx>]

If you jumped the RPM relay, as you said you did, and you can hear the fuel pump running, that indicates that all is well with the fuel pump. The fuel pump needs at least 9 volts to operate therefore it is unlikely that you have only 4 VDC at the pump. You keep mentioning the main fuel relay; the RPM relay is the main fuel or fuel pump relay.

Once again; repeat the brown to white/purple jump test. The brown wire is 12 volts hot to the battery, therefore you should also see 12 VDC at the white/purple wire.

If the fuel pump runs when the RPM relay is jumped and the car will not start you have a problem other than the fuel pump.
