Bad new ICM?
Hi all,
My truck died 6 months ago and I was too busy to fix it. turned out it was the Ignition Control Module. No fire, no fuel. I replaced with with a GM original. now she is ROUGH! Hard to start. Idles rough. Backfires. Hesitates. I put in fresh fuel. Same problem. Bad ICM or should I look at something else? Yes. I did put the thermal paste on the new ICM. Thanks 1990 350 R1500
