I have a 2000 z24 that I've turned into a race car. Car was running on 3 cylinders and it turned out to be a bad coil pack. Changed it, started it and it ran for 5 mins. Shut it off and put some tools away. Went back to start and nothing. When I turn the key the dash lights up, fuel pump turns on but as soon as I try to start it its dead. Nothing. Battery is good. Checked all the grounds and fuses. It is in park. No code on the obd. Any suggestions?

Thanks

If it doesn't turn over at all maybe the starter is bad?

I'd say give the starter a few good wacks
