Fuel pump will not run. Main fuel pump fuse blows continuously. With ignition key switched off, main fuel pump fuse contacts are live - even blew a 25 amp fuse! Only way to make them safe is to disconnect battery. Help please!
Fuses mean short somewhere.Fuse is always live it feeds relay but in tank pump [ fuse#4or#6 i forget anyway visa versa ] is not live until this.Relay clicks once when key tuned to on and once more when key turned to crank engine it is under dash by glove box and loud enough for someone with ear at this spot to hear.In tank pump should not be live until engine starts to crank.
If the main fuel pump doesn't begin running when jumped (you should definitely hear it humming), you either have a faulty fuel pump or faulty wiring to the pump (bad wiring is really common under an old 240, near the pump). This test of course assumes your battery is good.
If one of the fuses blows during this test, the pump circuit wiring is shorting to ground somewhere between the fuse panel and the pump.
thx
