There has been two occasions when my car just cranks and won't start. It's getting gas I can smell it. Both times I pulled the front driver side plug wire and set it close to ground to check spark and the engine fires right up. What would cause this?
Do you have a ground wire directly from the engine block to the battery or frame ? One of these locations would be good, both wouldn't hurt either.
I know there is ground from battery down, but not sure where it connects. I will double check that. Might run one from the frame to block. One of the guys at work was questioning a ground issue, since that is essentially what I was doing with the wire.
Sounds like the ignition module is going bad. I use to take the distributor cap off, say hi to the insides, replace the cap and car would always start.
By doing that your forcing the coil to jump a larger than normal gap. Coil goes to max output. Keep that in mind. You could be dealing with an ignition issue. Bad plugs/flooded plugs/bad wires etc. Tough to diag on the net but food for though I guess.
I've seen people pull the coil wire out and let it arc into the cap. they say it gives a hotter fire to dry flooded plugs... ......
