89 7m-gte some times no spark.

[rap2chin]

So I got an 89 7m-gte there's no check engine lights. What happining is. Car will start and run perfect when it does, but on ocassion it won't start I'm gettin fuel everythin powers up, but no spark the car will do this for about 5min to a couple hours depending its mood haha. So I don't get it and the 5 or 30 min of it not starting it will just start again.

Oh and when it just cuts off everything stays on just the engine dies.

dude omg that shit happens to me too i got the same problem...still dont know wtf is going on...let me know if u figure it out bro

Try checking and wiggling the CPS wires. They get brittle/corroded and is a common way to have intermittent starting/spark.

Hey what u up to I was thinkin its the igniter what u think ans where is the CPS sensor wires what it next to a pic would help.

From my understanding and from what I read it might be the ignitor or the CPS sensor. But I don't think its the ignitor since I have power to it while I'm not gettin spark. U think I need to just adjust my CPS sensor?

Do not adjust your CPS without a timing light. I'm saying to just wiggle the wires on the harness.

sweet thats what i thought. if they are brittle is it a doable job to rewire it ur self.

 

[suprakidd]

i snipped the wires on mine and wired in better condition clip on mine... lucky i got the same wires colors in the cps and harnees.. if u dont just remember to write down what wires went together..

so supra im guessin u had the same issue and u fixed it.?
