so my car shut off goin 65 so i pulled over checked for power out of spark plugs............nothing and i dont even have power to the coil...............so i ran a wire from the battery to the red and green wire goin to the coil and i grounded out the black wire goin to the coil and i still have no power coming from the coil! ideas?!

Check cam and crank position sensors. If either is bad there will be no power to the ignition.

just talked to an actual mechanic in a shop......i got it figured out i feel dumb now......ok so i have code 54...........54 No sync pickup signal during engine rotation (turbo only)
OR
54 Internal logic module fault ('84 turbo only) - or camshaft sensor/distributor timing

which explains y i have no power coming from the distributor....so he said its probably the cam that is bad. the two wires goin to the coil energize it but the distributor gives it power... so that explains my check engine light and why i have no power going to my coil and no power from my distributor

Check the fuse panel under the hood for a blown 30 amp fuse, if there is a blown fuse take a peek at the o2 sensor wiring and see if it has worn through or melted to the exhaust header. If that is not the case it could be a bad crank or cam sensor. You need voltage and a pulsing ground at the coil, if you have no voltage look for that fuse as mentioned earlier. No pulsing ground would indicate a bad cam or crank sensor. Might as well replace both of them if one is bad.

I just had this same issue, the Crank PS
wires where actually melted by the exhaust
spliced them back together and fired up

so i just replaced my distributor......the old one had broken teeth and was locked up...weird...so i put the new one in and it turns and functions right...but i still have no spark.....here is what ive done: ive replaced the cps, the coil, the distributor with the sensor in it and i stillllll have no spark or power to the coil

Read post #4 again.

the 02 sensors wires were fine all my fuses are good the camshaft and crankshaft sensor have been replaced so im still stuck in the woods

Trace the primary wires from the coil and look for damaged wires. Do you hear the fuel pump kick on when you first turn the key on?

goblinish15

yup pump is priming ive traced the wires and the black one is fine it runs to the alt. and the green/orange one runs to the fuze box and stops there and the asd relay is golden i swapped it out and still cant find anything wrong! the only thing so far ive found wrong are the broken distributor teeth...which ive swapped and the distributor turns now and is all in check! so thats where im at! stuck haha

goblinish15

maybe my ecu is bad? the one i use to have had a bad volt re. i had an external one wired in...then i got a new ecu so maybe the new one is bad

goblinish15

ideas anybody?

You have no voltage to the coil, the ECM does not supply the voltage to the coil, the ECM switches the ground. You have an open someplace in the coil circuit.

so i looked at the new coil and it was melted........put everything to the way it was and BOOM it runs....so im thinking the distributor teeth broke and locked up screwed up the whole ign. system....but it runs now


now for a new paintjob

I think you just had a shorted coil.
