1996 Chevy Astro 6 cyl All Wheel Drive Automatic

I'm working on a 96 Astro van and have run out of ideas. Symptoms are: Cranks but no spark to plugs. Also, the trouble indicators on the dashboard do not light up when the key is turned on, only the light behind the transmission indicator. Checked power to crank sensor, ingition coil and ignition module - all had no power. All fuses are ok, but no power getting to the small ecmB and ign fuses in the under hood power center. Tried to read possible problems with a code reader, but only get a linking error. I changed out the PCM and that didn't fix it either. Next stop is the ignition key switch, but looking for more ideas. Thanks![/quote:0f4f72f5cf]


Have you try checking the timing chain? i have trouble with a car that i didnt get spark to the plugs. maybe work a try then again i could also be wrong
