i was out driving today and my throttle got stuck at a light so i tried wating for the light but was force to run it i got the throttle unstuck and kept driving. the car started sputtering and missing real bad. i limped it home and turned the car off and started it a couple times to try and figure the problem out and couldn't track it down. i just went out and now it wont start. it fires when the starter is running then once i disengage the starter id dies. is there a way to tell if the module is toast? antifreeze dripped on the ds2 harness connector i don't know if that did it but im stumped.
 
Did you hook up the white wire? IIRC that is the start mode that many people dont hook up. Im not sure if it can be powered from there or not. It may be that your regular power source isnt working only the start one is? Back in the day when these were running everywhere I remember it was not an uncommon failure to have either the run or the start mode of the module fail. I remember the symptom being you got a pop when you let the key off. Was your throttle stuck wide open? Perhaps the voltage was a little high and it damaged the module? Where did the antifreeze come from?
 
it wasn't wot about 3/4 and for like 30 seconds. the antifreeze came from the overflow over flowing. and yes i did hookup the white wire to the start terminal. it worked great till this afternoon. it is showing hot at the coil when the key is one on both terminals
 
i got it to run by plug the white wire to the red in the run terminal and it ran really good i pulled it out to take it down the street and i went a couple blocks and it started stumbling again it ran ok in 3 gear pushed to the floor.
 
I'd put my money on the module, the stock ones don't like heat, once had a work truck that would start missing and backfiring, poured ice water over it from the cooler, would run fine til it heated up again, would guess that the heat that caused the overflow was more at fault than the anti freeze. And remember when you're running on the white wire the timing is retarded, try a new module, I always keep a spare anyway.
 
Could be a carb problem. Or vacuum leak. The electronics on that vintage car are pretty solid.
However I would also check the freedom of movement of the advance plate in the dizzy.
If it was sticky or damaged it might cause the symptoms you initially described.
And some WD40 in there too to displace the moisture.
 
it turned out to be a combiation of the one of my splices pulled out, thats why it wouldnt start, and seems to have been vapor lock that caused the cutting out. i replaced the module and it still stumbled then i bent the fuel line while it was running and 15 seconds later i was messing with the choke and it got really smooth then ran fine. thanks
