1981 Mark VI problem

hudgmanvi

I just purchased a 1981 Lincoln Mark VI coupe with only 23,000 miles on it. It has been in a climate controlled garage and has not been started in about 6 years. I replaced plugs, plug wires,air filter,fuel filter,fuel pump,fuel pressure regulator,fuel injectors and computer. The car ran great with no problems. I drove it about 10 miles and then it just quit! After a while it will start and run about 5 minutes and quit again. Do you think it could be the ignition module? I am running out of things to replace.

What did you do about the old gasoline that was in it? Was the gas tank dropped and flushed?

I forgot to mention I also replaced the coil.

Mr_Shiftright

If you did that, next thing I'd do when it stalls is to squirt some starting fluid in the throttle body and see if it starts right up--if it does, then you have a fuel delivery issue.

Also, testing for spark is an easy matter using a simple spark tester you can buy at Autozone

Well, I replaced the ignition module yesterday. I drove the car all day today with no issues. Well, at least until about an hour ago. We were driving through a housing area looking at homes and it just quit running. Would not start. We walked home and about an hour later drove over to were we had left it and it started right up and I drove it 2 miles back home. I am at a loss on what to do next!

Mr_Shiftright

You'll have to test the car at the time of failure. Guessing is just going to frustrate you I think. Next time this happens, when you crank the car over and over, does the tachometer needle move?

It has the digital dash. I haven't seen a tachometer
