I have a 97 chevy cavalier, it doesn''t start, it start to crank up but it just won''t start. I just changed the fuel pump, fuel filter,did a tune up, changed plugs, cables, air filter,oil and also replaced the crankshaft position sensor. sometimes it starts and others it just won''t at all.39480.6130091782
Optional Information: 1997 Chevrolet cavalier 2.2Already Tried: changed fuel pump,fuel filter,tune up,crankshaft sensor
Any trouble codes or is the check engine light on? Have you verified nice blue spark on all cylinders and fuel pressure more than 45 psi and not dropping key on engine off? Is a scan tool available to monitor the engine sensors?
