1995 Chevy Camaro

If the engine cranks over but there's no spark, then r it could be, from simplest to hardest:
1) Crankshaft position sensor
2) Camshaft position sensor
3) Coil/Coil packs
4) Ignition control module

There's no way of telling this without interrogating your computer. (You have an OBD I system)

If you go to AutoZone or any other major parts dealer, they should allow you to use their scanner for free.

Once you get the trouble codes from the computer, ask them to give you the definitions.

This will tell you what's faulty, but not necessarily why. This information will give you a starting point.
