Hi, I have a problem with a blown ballast resistor in the ecu manifesting itself by showing the key code light and immobilising car, this apparently has been caused by a wiring problem on car,after many hours fault finding on car wiring unable to find a fault?. guy says obviously if i have ecu repaired and then plug back in if fault on wiring not solved then blown resister again.
question is can i run fuel pump and ignition from a relay powered up from ignition key?.
