Re: HELP PLEASE! Engine Trouble

It's not always that excessive fuel will ruin a spark plug but it may cause misfiring. My guess is the fouling causes the spark to jump the gap to ground. In most cases where the spark plug is new and clean it can be dried out an reused, however, the cause of the fouling has to be eliminated first.

If the spark plug already has oil or carbon buildup on top of the fuel soaking, it's best to replace them.

From http://www.briskusa.com/basic_theory...plug_operation

Fouling

Will occur when spark plug tip temperature is insufficient to burn off carbon, fuel, oil or other deposits
Will cause spark to leach to metal shell...no spark across plug gap will cause a misfire
Wet-fouled spark plugs must be changed...spark plugs will not fire.

I don't know what causes it but I have seen cars that wouldn't start after flooding even after sitting for a couple days. Change the plugs and they fire right up and run normal. I had an old mechanic friend to show me this when I was a teenager and I didn't believe either until I saw it.

Re: HELP PLEASE! Engine Trouble

I just wanted to thank everyone for your help!!!! 67 chevelle nailed it, It was the wire that ran from the distributer to the starter. I ran a new wire from the distributor through the fire wall to the ignition terminal and that ***** fired right up . My dog thanks you too since it's his truck I'm just the driver

Maybe it was good, but not quite good enough.

It had spark but I don't think it was enough to keep it going

Re: HELP PLEASE! Engine Trouble

I think what confused a lot of us is the fact that you mentioned the truck ran find before it stopped.

However, if the truck was using the original resistor wire or if the wire was bad that would cause it not to have good spark also.
