fire?

okay gurus, i just removed &,cleaned the fuel tank, rebuilt the holley carb, installed a new starter.solenoid, the engine turns over but will not run. it acted like it wanted to once or twice , but ive got fire to the coil and out the coil wire to the electronic dis. but no fire at the plug wire end. by the way this is a 1980 PCM 351. thanks

Do you have correct firing order. Remember its reverse rotation.

Was it running before all this work was done or nothing

Start with the things you have touched first,    I suspect that in the cap and rotor cleaning, something is not making contact.   Could be that 2 things have gone bad at once.   Electronic ignition is known to fail, so while I hate throwing parts at things, you may have just experienced a failure.   Failure can happen all of a sudden with those things, and I don't believe there is much of a way to test them.

Don't pull it,a Ski Supreme engine turns the opposite direction and will not fit.

Richard,
The EI conversions are always suspect to failure. Do you have a means of checking for spark such as a timing light? If you don't have one use the old back yard trick by removing a plug, grounding it and looking for spark while cranking the engine. A better static method I like to use without having to crank the engine is to remove one of the plug wires from the distributor with the spark plug . Plug it directly into the coil. Remove the - ground wire from the coil to the distributor. Put a jumper wire on the - coil. With the spark plug grounded, turn on the ignition switch. Intermittently ground the jumper wire looking for spark at the spark plug. You should get spark at the plug when the jumper is removed from grounding it. If you have spark, and didn't when the EI conversion was supposed to intermittently grounding the coil, Trash the EI conversion!! Go back to the good old points that WORK!!

I always ask why was the EI conversion done?

Very good advice Pete. Being an EI fan I have to disagree with going back to points, but we are allowed our own opinions.

By the way, have you looked into a conversion to go back to points in your SUV??

my daughter is so made the boat is down!no spark at the plug after the jumper wire was grounded on and off. what does this mean?

there is no spark at the plug after i take off the jumper wire against the manifold

12.1 volts to the coil,plug wire with plug attached grounded to the manifold, i used the same manifold to ground the jumper wire off of the coil ground.

Richard,
Sounds like a bad coil but here's some youtubes on testing to make sure. Also, get an Ohm reading off the primary winding of the coil. Is it open (infinity)? 12.1 volts to the coil? The ballast resistor is by passed? Is the coil you have internally resisted?

Lucas' nickname:   Prince of Darkness!

Richard - you can check Ohms resistance of coil primary. Usually they will be open (infinite) if bad.

Doc Brown did it with a FLUX CAPACITOR , just have to make him run 88 mph
