Stranded on River!!!! Bad Coil?

[subysti]

Engine is a 1996 5.7 2bbl #F882665. Sometimes starts hard. Seems worse when hot. Cranks over but no start. See fuel pumping in to carb when throttle is pumped. Removed distributor cap and cleaned all the contacts even though they weren't that bad. I think I have no spark and I thinks it be the coil. The checked the main wire going to distributor and it was pretty gunked up. The thought it was dielectic but it seemed hard and sticky almost like epoxy. I cleaned and reinserted but it came out with more of the same crap. It looks like the original coil so I should probably replace it anyways. New wires, plugs and cap and rotor last year. I've heard that coil problems get worse as they heat up which make me lean to that.

thanks for any ideas....

Re: Stranded on River!!!! Bad Coil?

have you checked for a no spark situation when the engine does not start??

guessing it has no spark and changing the coil is not troubleshooting, 90% chance your coil is just fine anyways, they rarely fail

are you sure you don't have a carb leaking down causing a flooded engine when warm??

Re: Stranded on River!!!! Bad Coil?

Thought I stated no spark when it wouldn't start, my bad Had a spark tester hooked up and wife said there was no spark when cranking. So between that and the goo in the coil I figured coil. I wouldn't know where to begin for a carb leak down problem. I'm not a carb guy, never worked on them.

I would look into a bad possible pick up coil in the distributor as well. You could replace the coil first. They are generally reliable, but the igniton module is more likely to experience heat soak.

I guess my real concern about the coil was the epoxy like goo that was on the wire. Aren't the coils filled with that as an insulator?
