electical problem

[kipper]

I''ve got a problem ,thought I had bad ignition switch . No power . Today got power and was able to connect tune ecu , threw fault codes P1231 an P560 disconnected connector A at ecu an reconnected cleared codes switched ignition back on an still got P1231 short to fuel pump relay . Manual tells me to do tests but don't know what i'm looking for in the tests anyone enlighten me R111r , Turbo ? Thanks

Check the fuel pump relay for proper operation. Also, use a multimeter to check the power supply to the relay. Two of the four contacts should have a voltage of +12 volts.

Yes got power on both wires also tried swappin relays

It remains to check the integrity of the wire from the ECU to the relay. First, check for proper functioning, and then check for a short circuit to ground or positive. If there are no issues, the ECU may be faulty.

forget about the way the manual says to check the circuit
in the beginning you said (thought i had bad ign no power that will set the p0560 code. this would be my concern. need more info on this,
when you turn on ign can you hear the fuel pump run. also can you feel the relay apply ?
when you turn on ign can u feel the engine management relay click?
if you have a main power problem you go after that first.
