I don't mean to double post but my prior one was in the wrong category
I gave 8t a decent amount of throttle from a stop and the Trac control kicked on and it back fired about 5 tines then died.. It now won't start and back fired still. I only cranked it with and without giving it throttle both with the same result,nothing..fuel pump primes and it's throwing no codes that would pertain to this. Could is be my crank shaft position sensor? The car occasionally did have a longer than normal crank at start and sometimes would run for a second or two after I turned off the ignition .. It is a 1997 z28 lt1 a4..
