I have a 2001 cavalier I drove it for about 3 miles and it just shut off like someone had turned the key off. I will not start now, it will crank. Replaced the timing chain and gears and it is in time and also replaced the crank censor in it. What else could be the problem with it?
Have you checked for spark? If there’s no spark the ignition module may have failed.

It is getting fire and fuel. But my opinion is that I think all the spark plugs need replaced and it may be something with the starter or the fuel pump
