I have a 1994 GT with a 5.0 V8 302. It will start up just fine several times and then all of the sudden it won't. I turn the key and it tries to start and just won't catch. I just replaced the coil and emmissions module. Any idea what this may be? Any help at all will be appreciated!

I'd pull codes from the computer first. I'd guess you are losing spark. When you are cranking, have someone listen and watch under the hood for leaking spark. It sounds like a snapping sound and often you can see it where it is shorting. I had a broken boot on my coil and it was sparking to the coil mount.

Hi,

When you say it doesnt catch, do you mean the motor is cranking over, just not firing up?
Does this happen after the engine has been ran for a while, or is it a cold start issue?

It is a cold start issue. Yes, it turns over, but won't catch. I have already replaced all of the spark plug wires, the ignition coil, distributor cap and rotor button. When I tried a new ignition module, it would not start at all, so I put the old one back on and it started right up, but now I'm back where I started. I will start fine one day and the next day, not. I hope this helps. Thanks
