just got a 91 gt and its getting no spark. i replaced the coil with a new one and i changed out the dizzy with a known good one. it has a 6al box on it and i disconnected it and still no spark. i also put new plugs and wires on it too. what else am i forgetting?
Make sure your engine grounds are good.

check the computer
i checked the grounds from the head to the firewall and the ground from the neg on the battery and i cleaned them. i changed the cap and rotor. i also swapped the computer and still have no spark. someone help me before this car loses its windshield.

Did you put the timing light on the wire from the coil to the cap? If you don't have spark there, it's usually a bad module on the distributor or a computer problem.
Another thing to try is the relay that is in the kick panel by the computer. I have seen where if it is bad there will be no spark also.
im not even getting spark to the coilOriginally Posted by Viper_ed
The 3 things I listed are all that I know of that will allow the coil to not have spark.
Did you verify that the coil is powered with 12v+ with the key in the forward position?
no, i dont have a tester
i know the computer and tfi aregood btw.
I know. You need to go spend $10 and get one. Radio Shack or Lowes.
check the connector by the battery tray it looks just like a fuse holder.My nephews car had same problem the acid from battery rotted the connector and he had no spark.
hey i quit bein a cheap ass and got a voltmeter but im not to sure how to use it.
Well, I see you either learning how to use it, or learning how to change a windshield.
check all the fuse links by the battey and check to see if u have power to dis if u have power control module bad
ok i just tested to see if i had power to the dizzy and coil and i have power to both but no spark from the coil. i dont get it. how can you have power to the coil but not have spark? the coil s NOT bad as i have tried 3 different ones off of my other stangs.
the control modle bad put a new one in it will run
Did you check that relay by the computer?
do you have the dist bolted down, not just setting in the block?? the dist has to have a good ground, If you can't figure it out just gimmi a call, i am sure i can figure it out for you...

Always make sure you have it bolted down when you try starting the car also. If not, I have seen where you can actually short out the module if it doesn't have a good ground like Timmy said.
Listen, take the dist out of the engine, leave it plugged in, then either use a jumper wire to go from the dist to the block or you can try to hold it up against something for a ground... leave the key on and unplug the coil wire from the coil and simply turn the dist gear, you should have spark jumping from the coil, if that doenst work try unplugging the spout, then turn the gear... I have seen one of the 3 power wires going to the ecu not working correctly (usually a fuseable link), taking out the spout and trying it helps use 2 diff "parts" of the ecu...
