01 Silverado keeps burning up ignition control modules,

Customer Question

01 Silverado keeps burning up ignition control modules, ignition coils, and crank position sensors. Is this a grounding problem?
JA: Does the vehicle stall at low speeds? Does it sputter?
Customer: Intermittedly.
JA: Are you fixing your Silverado yourself? What have you tried so far?
Customer: Trying might be more accurate. Replaced distributer cap, ignition system held up for a period of months after that. Ignition control modules have lasted as little as 2 months - verified failure at auto parts store. I'm wondering if I'm getting a power surge somehow.
JA: Anything else you want the mechanic to know before I connect you?
Customer: Yes. Problems have stranded driver - stalled while driving. But mostly cases of no start - no spark condition. It does get fuel.

The most likley cause of this condition is either faulty new parts or a bad PCM.

I would rule out faulty new parts first and then replace the PCM as needed.

Hope this helps!!
