Check the timing and make sure the vacuum hose for the advance is not leaking or cracked. Also make sure it is plugged into the front of the carb at the base.
If the timing is dead on and there are a lot of miles on the timing chain, bump the timing ahead 1 or maybe 2 degrees to compensate for chain stretch. That may help.
It could also be that the vacuum advance on the distributor has started leaking and may need to be replaced. You cuold also try a tank ot high test or premium gas. That has been known to get rid of spark knock. Hope this helps.

Why wont it spark


Someone needs to check for voltage at the coil and the distributor.
The pickup coil in the distributor tells the coil when to fire.
If you are getting spark at the coil tower but not at the plugs, check the cap and rotor.

Have a 1993 f150 4x4 5.0 / 302 new coil new ignition module new distributer cap/ rotor wires and plugs not getting fire from the coil??? please help


Check pickup ring inside the distributor sounds like the wire is broken and make sure you have power going to ignition module. If you don't go to library and use their all-data services for test procedures for no spark condition. If you have power to ignition module i would say its the pick up coil in distributor. This system is a pretty reliable one. I have seen new modules that where bad so you might have yours tested by your local parts store most of them will test them for free or a small charge.
Good luck I hope this helps get you back running agian

1983 town car 289 sometimes it starts sometimes not no ignition. replaced ignition module ,throtel position sensor coil dist.cap,and rotor.Thanks


THERE IS A PICKUP COIL IN THE DISTRIBUTOR, IF YOU HAVEN'T CHECKED THAT, IT IS PROBABLY EASIER TO CHANGE THE DISTRIBUTOR THAN TRYING TO CHANGE JUST THE PICKUP COIL. MAKE SURE THE PICKUP COIL COMES IN THE NEW DISTRIBUTOR BEFORE YOU BUY. THE PICKUP COIL OFTEN CAUSES THE PROBLEM YOU ARE HAVING WITH YOUR CAR

I have no fire in my spark plug wires and i'v replaced everything.


Try disconnecting the four wire connector at the distributor,jumper terminals "A" and "C"(black to green) on the distributor side. this eliminates the ESC module and lets you deal with basic HEI. ohm the pickup coil 500-1500 ohms.use an ac volt meter white wire and green wire in the dist.,crank the engine.at least .5 vac,usually about 1volt.low voltage with a good pickup means a weak magnet.New cap& rotor? I've seen rotors burn thru...they look fine but will arc down to the advance weights.Make sure you have at least 9v at the big pink wire while cranking.disconnect any aftermarket tach,unplug the factory tach at the cap...If you installed a hi output coil,they are tough on ignition modules...Some things to try.

I have a 1998 chevy silverado when trying to start it it acts like its out of gas and just keeps cranking and will not start. i tryed spraying starting fluid it carb thinking it might be fule pump but...


Check to see if it has spark. It may be having a problem with the distributor. If you have put fuel to it to no avail, then you probably dont have spark. Could be the cap / rotor, the coil, the pickup in the distributor, or power going to the coil or distributor. Check for spark and if you dont have any, make sure you have power to the coil / distributor. If you do then try a new coil cap and rotor. Hardest part would be the pickup in the distributor if thats bad.
Heres a link to an article on the types of distributors and how to rebuild them.

I had the same problem with my 85 cj7 this week, I relpaced the ignition control module, plugs, wires, cap, rotor and the the coil; still had no fire to plugs. the problem turned out to be my distributor, replaced it today and she fired right up. Most likely it was the pick up module in the distributor that went bad.
