Saturn Repair Problems? Ask a Mechanic for Answers ASAP
Hello, my name is***** sounds like your ignition module has failed or possibly crankshaft position sensor. Disconnect the ignition module and check for 500-900 ohms resistance between the Purple and Yellow wires. Check for 500 millivolts (mV) AC output or more at a fast cranking speed. If cranking RPM is shown, disconnect the ignition module. Verify there is good power on the Pink wire and a good ground on the Black wire. Check the ignition module trigger circuits. During cranking, check for a 0-5 volt square wave from the PCM to the ignition module on both the White wire and the Orange wires. These are the coil trigger signals sent from the PCM to the ignition module.
