Re: An elusive engine problem !!

sounds like something that happened to me...
What it was in my case was damaged distributor cap. If it's not that I would be apt to check the rotor. If you already checked all the connections though *shrug* I dunno, someone else will probably know more though.
good luck

Do you have after market wires, that are low resistance?

Re: An elusive engine problem !!

sounds like you replaced the fuel pump but did you replace the fuel filter too? I had a glogged filter that would do that slow to the point the truck wouldn't run anymore.

Re: An elusive engine problem !!

Is the ignition timing good? I had similar problems with my truck. I had a bad distributor cap. I replaced it and it seemed to help a lot. It still didn't seem powerful enough. I took off my timing cover and was missing 10 teeth off one of the gears and i could fit my finger between the gear and the chain. Have you tested to make sure you are getting plenty of power to the coil or off of the distributor?
