That could be a timing issues when it back fires
Why ,no idea,not a question you can guess at as we do here
Could also be a vacuum leak & lean fuel mix
When you say cranks the motor turns over nothing else
Cranking has nothing to do with the motor starting or running
You have a no start & back fire as I gather

What would cause my 1996 Chevrolet Silverado 1500 with a 350 Vortec engine to backfire on occassion when I crank it?


The distributors on these GM trucks should be replaced at least once a year. Any check engine light on? The crank sensor can cause it to backfire as well.

2001 pontiac grand am gt won't start. Cranks normally but no start. Backfired also after a few tries. Fuel pump turns on so I Replaced fuel filter but it still won't start.


The backfire means that it is a timing issue. The problem is most likely the crank shaft sensor. It tells the computer when the engine pistons are in position to fire.

96 chevy tahoe won't start?


Mine did this with a cap and rotor. I changed it six months prior, but ended up having a faulty cap from Jegs which caused it to backfire. I had crank, spark, fuel, but the cap was crossfiring and wouldn't run.

This cost me a new flexplate, two starters, still a cap and rotor just due to the backfires.

Will not crank and backfires


Hopefully, it is a mis-timing of the ignition and not an improperly installed timing belt or chain. The latter cold be fatal to the engine. I suspect that was not a cheap replacement so I wouldn't delay having it checked.
