I have an 86 740 gle non-turbo, 4 cyl. I ran it off in a snow bank, got it jerked out and it was running fine, idled a couple of minutes and died, all fuses are fine, ignition gets fire to the + side of coil, but no fire out of the coil, changed coil, no joy. In the past this thing has died while idling but always starts back up after a few seconds, cap and rotor look good. There are three wires in the plug to the distributor, which one goes back to the coil, and which ones are hot ect? Could this be computer prob? Any help would sure be appreciated.
Thank you,
Corey

 

Is the plastic part of the plug broke?
Do you have injector pulse?

 

Thank you for responding,, no the plastic part of the plug is not broken, I have not checked for injector pulse, but it does seem to be getting fuel, in fact after messing with it for a while I could smell gas. I will check to see, will a 12 volt test light work? Also could it be the spark amplifier module be the problem? Thank you.

 

Yes the Amp can be the problem. But the pickup in the Dist could be bad to.
You will have to use a noid light to check for pulse.
The injectors have 12v and the computer pulses ground to activate the injectors.

 

Thank you for the info, I hope for some more. Of the three wires going to the distributor blue, red, black, the red tested hot with key on, the blue fires injectors when grounded, the black shows to be grounded. with the wires connected to the distributor as it turns over the injectors are firing but still no fire from the coil, tried different coil, no joy. When testing the wires going to the amp, #1 and # 4 are hot with key on. Could the computer at pass side kick panel be the prob? Any info or advice would sure be appreciated.
