We have a 93 civic dx put in a new main relay and a new ignition control module and now it just cranks and won't start. Out of ideas here. All we where trying to fix was a dieing when at idol when once warmed up and not wanting to start for a hr once warmed up and shutting it off for 15 min.

Please gather more information.

Any CEL codes?

Only when the engine won't start:

2) Does the fuel pump prime?

3) Is there bright white spark at all 4 spark plugs? Click spark link in my signature.

Does the engine now start and run? If not, then check the mechanical timing to see whether the timing belt skipped some teeth.

One good way to check for skipped teeth on a belt is to take off the upper timing cover and if the camshaft is not turning, your belt jumped or is locked up.
