Incorrect timing, spark plug wires not installed correctly, timing chain worn out and has jumped a tooth, or distributor worn out.
Engine timing is VERY retarded. My first guess: the distributor clamp has loosened.
Timing is out your distributor could be one eighty out try turning it one eighty.
Bad spark plugs, spark plug wires or distributor cap and rotor.
The ignition module that is in the distributor is probley bad.
Having no catalytic converter installed is illegal and can cause a myriad of problems. Probably not a backfire though.
Not typically. Usually backfiring is caused by either a damaged distributor cap or an engine ignition that is seriously mis-timed.
Depending on what engine is in the vehicle, it may not have a distributor. If the engine is the 5.7L it does have a distributor. If you have the 4.8L or the 5.3L these engines do not have distributors.
Could be spark in the motor, or the distributor and rotor need to be replaced.
There are several things that can cause your 2000 Chevrolet to backfire and die. The most common cause is a plugged catalytic converter.
its running too rich down tune youre carb
