Engine Performance problem
1985 Buick Somerset 6 cyl Front Wheel Drive Automatic 100000 miles
After hitting a very deep pothole with the right side wheels stopped vehicle after proceeding another two blocks Shut off the engine to run errand and when came back 10 minutes later car would crank over but not start - finally, after extended cranking it started but ran very poorly and finally died as I pulled up in front of my house about 6 blocks away. Continued cranking only produced a couple of backfires and a couple of puffs of black smoke. Car continues to crank over, fuel pump can be heard priming the fuel rail, believe spark is present but have not tested injectors or taken fuel pressure reading.
Could this be a sensor problem? Vehicle had been running very well before this happened? Tried the injector power connector test using a test light on ONE injector and with the ignition key on I get voltage on BOTH connector terminals NOT ON ONLY ONE as the test procedure states. What does this indicate?
have the same problem?
