hey all. I have a 1984 f-150 with the 300-6. Had a new distributer put in. coil also. since then I dont have fire on cyl #3 or #4. I have checked all the oms. and all seems ok..Im hitting a wall here. anyone ever had this problem or have advice?..it would be greatly appretiated.

 

It could be plug wires, distributor cap, spark plugs themselves, or maybe even the rotor button.

Can't imagine its the distributor or coil since they would loose spark to all cylinders.

 

tried all the above..next on the list is the stator..I think.

 

Hmm, thats a tuff one. I had spark problems on my '78 and it turned out to be the pick-up coil in the distributor, but mine wouldn't start at all.

Hopefully somebody knows whats up, have you tried posting this in the classics section for older trucks?
