I have a 01 cavalier 2.2, just had to replace the timing chain. After TC replacement, car was running fine, then just would not start as if not getting fuel, but at same time randomly all dash lights would come on while driving and gauge cluster would stop working, i replaced fuel pump and filter, car started and ran good for 2 days. dash lights and gauges started messing up again and now car will not start? I have heard the ICM, crank sensor, ignition switch...what is your opinion?

 

Welcome to the forum. It sounds like you have an electrical problem, maybe busted or corroded battery terminal connectors, or worn ignition switch. How good are you with electrical measurements?
