Basic fuel pump wiring harness diagram - Gasoline pump relay manage - the laptop on gm gas injection systems is designed to govern a gasoline pump relay.? the pc does this by means of deliver a 12v (wonderful) signal to the relay.? the sign is only gift for two seconds at key on. Gasoline pump operation resumes when cranking over.? the pcm simplest instructions it again on while the pcm reads that the engine is turning over.

Some accessory positions on key switches aren't hot when cranking. This also consists of older cars that had points ignition. Even the coil cord on a number of the ones went lifeless whilst cranking. That is because whilst cranking the coil became boosted to 12v through the r terminal on the starter solenoid.? after cranking, electricity changed into restored to the coil via a resistor, lowering voltage to 6 volts.
