First post here and I’m hoping someone could help. I inherited this 2005 Chevy Impala a couple years ago with some issues. Basic stuff to start with. A couple weeks ago, I gave it all new plugs and wires and an oil change. Car was driving fine with no issues.
I stopped at a friends to help with moving furniture. Waiting for them to move their truck to drive to the next destination, I started my Impala and let it set in park. I shifted into drive maybe a minute after starting and the car lunged slightly and cut off. Since then, I’ve had crank but no spark. I had a somewhat mechanically inclined friend look at it and he ended up noticing a split ground wire for the ICM. Repaired ground and it didn’t fix my issue. I replaced the crankshaft sensor, ICM and now the Computer (with a programmed unit) and still I have the same issue. I have now back tracked and done tests on the wires from the ICM to the crankshaft sensor and everything seems correct. I feel like I’m missing something. Anybody got any ideas to make this thing run again?
