hi there, hope you guys can help with this one, i have a 97 grand prix se that was running like a charm. about 2 weeks ago i did LIM gasket and was running fine after, but yesterday the car won't even start, after 3 or 4 attemps the car started but shut instantly. fuel is ok, but spark is intermitent, what can cause this?
 


ignition checked, changed spark wires and plugs, also crank sensor, cam sensor, but still have this problem!:th_depressed: how to check vaccum leaks?
 
spray around with carb cleaner and listen for the engine to rev up..
which you cant do if its not running.
i dont think a simple vacuum leak would kill the car tho
