1994 Chevy s10 and it has no spark you tested the coil with a ohm meter and it was ok so you replaced the ignition modual still no spark what is the prob?
Have you run a diagnostic test on the vehicle yet? Many vehicles
of that year will self-diagnose problems and let you know what's
wrong. It could be the pickup coil, a poor connection or even a
faulty keyswitch... but you don't just replace parts until you find
the problem. That just introduces additional problems for you.
