1998 Chevy Cheyenne V8 Four Wheel Drive Automatic 115000 miles
I found the negative battery cable insulation was melted, core corroded and the positive cable had a bad connection. Replaced both, still no spark, replaced cap and rotor (was replaced 2 months ago, ignition module replaced 8,000 miles ago, battery replaced 2 months ago). No codes come up with autoscanner. 12 volts going to distributor with ignition on. Truck turns over strong, resistance of coil is 5500 ohms(new one bought and returned 6000). Getting a low voltage pulse from the cam or crank positioin sensor to coil. What do I do now? It is a 2500 5.7L with the 140 amp alternator. My multimeter only goes up to 20K and don't want to see if it will blow up checking for 40,000V leaving the coil. Is is my ECM or Ignition module and how would I know? On hah, unrelated, Fuel pressure is good.
have the same problem?
