September 11, 2006why did you replace the distributor,did it run ok before?what dist did you have before,and do you have now?go back to ground zero,#1 top dead center,check timing mark on the ballancer are you a tooth off?how is the dist advance,vacume,full machinacal?some are computer controled on the timing.
September 12, 2006the coil had an ark/spark comming out from under the plug and it kept backfiring and spuddering. i put a plug wire with longer end on it to stop it from arcking. that helped but finaly backfired bad and wouldnt run at all. now i changed everything and it just runs like crap.... checking the spark plug gap 1st. changed those also but didnt gap properly.
September 12, 2006there agin what dist.hei?coil in the cap?or external?if in the cap and there were burn marks on the coil or in the cap,it was bad.check your firing order for your spark plug wire's,dist timing check with #1 plug out,take the coil wire out have sombody or with a remote starter switch roll the engine ouer slowly with your finger over the spark plug hole till the compression blows your finger off the hole,you should be close to top dead center,roll the engine over to the timing mark on the cover tab for the amount the truck is to be timed at.check were the rotor is pointed at should be(#1).if not the dist is retarded or advanced.correct.if hei check out the module and the stater pickup some of origonal wire's were to short'and would break with age check were they go into the pickup they frey there when the dist advances over time.the new ones have longer wires.good luck!
