Pontiac Repair: 1993 pontiac quad 4 no spark 3 & 4, crank sensor, cross firing

Question
I have a 93 pontiac grand am. Has no spark on 3 or 4.

Ignition module or crank sensor?

Answer
Hi Keith:

I don't think it's either. That engine has 2 coils in that housing under the engine cover and those cylinders are on different coils. so the companion cylinders 1 + 2 are firing ? so the coils would be good. I'd look at the boot assemblies between the coil housing and the plugs or even that coil housing. with high milage the had an issue with cross firing inside the housing and not firing the plugs. I's say the module is okay because you have spark on 1 + 2. Again they are on differnt coils so the module is firing those coils. Good luck :)
