I drive my car for 6 months. I came
home one day and went inside n20
minutes later I come out and the car
would crank but not fire. Ive since
learned I have no spark to the spark
plugs but I do have fuel to them. Ive
replaced the ignition coil, plug wires,
and ignition module. I have NO idea
what else it could be. HELP!!!!!

Get yourself a spark tester and start testing. Work your way back from the plugs to the distributor cap. Open up the cap and check it and the rotor for corrosion. Get a DVOM and test the crank position sensor.

The plugs are good but no spark. Tested the coil and cap and there is power to the distributor. When I replaced the module the rotors were Fine and the distributor was clean.
The security system has locked up if you have no spark and everything else is good. Unplug the battery for a long time one day(s) or tow to dealership to have vehicle's computer reset.
I have a 1981 Pontiac Firebird change coil change the plugs change ignition and still no spark no start
97 firebird no fire at sparks want start
