Have Classic Car Questions? Ask an Expert.
Hi, I’m Ron and I can help you.I have been in this business since 1975 and also teach automotive repair. I am confident we can resolve your problem together. Please understand that I don't know your skill level. I can't see, smell, hear, or touch the vehicle either, so it may take a few replies to get to satisfactory results. Please be patient!I also try to give all of the information you may need, expecting a “positive rating” in return. I will also continue assisting you after you have rated me, if necessary. If there is any reason I cannot get a positive rating, please let me know why “in advance”, so I can go another direction for you. I am sorry you’re having this problem; I’ll help you through it.
Does this model have a distributor? If so, make sure the rotor is turning when you're cranking the engine. If it's not, then you have a broken timing belt. That would explain no spark to the plugs. Let me know.
Check for 12 volts at the positive side of the coil from the ignition switch. If that's ok, then the distributor may be the problem, very common. Also, please don't forget to rate me:)
The rotor is attached to the top of the distributor shaft via a screw or pushed in place, depending on that design and should turn with the cam. If all that's good, then the distributor is bad.
Yes there should be spark. Then the rotor is grounding out at the top of the shaft.
OK, one more time.
power to pos side of coil from ign sw.
when cranking, pulsing voltage on neg side of coil.
high voltage out coil tower through plug wire to plug.
The ignition module. or coil.
I will continue to assist you after you have rated me too.
Thanks again, Ron
I think have have proven to you that I'm willing to continue helping you. I don't blame you for not wanting to throw parts at it. But your skill level may "respectively" be an issue here too.
That "AT HOME" procedure, is VERY inaccurate because it DOES NOT load the module or heat it up. Good luck to you.
