I have a 1993 buick regal with 3.1 liter. Car started stalling off and on over two week time period. Eventualy the car would not start at all. So far I have tested the crank sensor, map sensor, camshaft sensor, the ecm, and ignition module. Also did secondary resistance test on the coils. It has spark, it has 42 lbs pressure at the rail, the regulator is not bad. The weirdest thing is the only thing that would get the car to start is to choke off the throttle body manualy. After started the car runs great, and then eventualy after so many restarts it will not start once again. Im lost!
have the same problem?
