well as i said before, i put in a new distributor, new coil, new ignition switch. and still get no spark from the coil. that is why i am guessing it is the ECM. i guess i will just pull it out and put in a new one and see if that is the problem.

 

Screw that coil , new or not it doesn't matter , could of been bad before you got it , you don't know until you try . where's your old parts? swap some things off the old with the new.

when you find the problem let us know

thanx and Good luck.

 

thanks. i will let you all know what ends up working. who the frick knows right? it could be a combination of things. it is just frustrating to keep dumping money in the thing.

so far i am up to $330 and then the cost of the ECM.

thanks for all the advice however, it is great to have a bunch of other heads working on this.

 

sounds to me like the ecm.here's how it works.
the ECM replaces the points, in other words it is a switch. when the switch is closed the primary side if the coil has power and creates a magnetic field.
when the switch is opened the magnetic field collapses and induces a voltage into the secondary or high voltage circuit. the 40-50K volts produced causes the sparks to arc across the plug electrodes. if the switch or ECM is not opening the circuit you will not get spark.

 

so any update on this as i have the same problem with my 1986 f150?

 

89ragtopgt: You don't give any details of your problem. But if it just up and quit on you and won't restart after cooling off, the ignition module on the side of the distributor is most likely your culprit. You need a special little socket like tool to remove and replace this, available at many auto parts stores. If I'm off base here, please explain your problem and what, if anything you have already tried. Or start a new thread.

 

Sorry 89ragtopgt. I didn't recognize your name from the thread you started.
