My 2004 Hyundai accent was ruinning good, but after parking it, it wouldn't start. The engine was turning over, but there's no spark from the ignition module on. I checked the timing belt and it's OK. What might be wrong?

Consider replacing coil packs.

Thanks. I had someone tell me it might be the camshaft sensor as well. What do you think?

If it doesn't involve the coil packs, I would focus on the Crankshaft Position Sensor.

I'll look into both of those suggestions. Thanks txgreasemonkey.

Get a diagnostic done, you'll put more money into parts you don't need if you guess the problem. I thought it was a crank sensor but mine turned out to be a bad relay that controlled the PCM.

Transmission would not go in reverse.
