Did you check the gap on the plugs prior to installation and does it run a little sluggish, you may have crossed two spark plug wires.

Backfire at 60 to 70 mph


Check for bad fuel, but it sounds like it might be spark plugs or spark plug wires breaking down and cross firing or missing. If it is electrical you should have a rougher idle also.

My 98 Cavalier was runnning great all the sudden every now and again it takes a couple turns to start, so i took it to Auto zone, they ran a test said everything looked good, and that I should change spark...


My guess would be two of the plug wires are on the wrong plugs.
The original problem could be a faulty fuel pump relay or the check valve in the fuel pump.

WONT START AND TRIES TO TURN OVER BUT BACK FIRES


AWESOME a real camaro problem.
backfire.
strong odor of gas because the gas isn't getting burned
caused from backfire. backfiring because the spark isnt sparking when its supposed to.
problems could be bad spark plug wires , bad plugs , bad ignition parts.
your gonna need to check wires for bad spots, check ignition coils and stuff like that. if all that stuff is ok, then your problems have to do with inside the engine. jumped time etc.

Rv backfired then died and wont start know


It could be your control module.Pull off a plug wire and see if it has spark when you turn engine over.
If you dont, it is most likley the module or the coil

Backfiring on acceleration of a 2002 GMC with 6.0 Engine


Backfires are usually caused by a lack of fuel...change the fuel filter. Also very old spark plugs (or plugs gapped to wide ) will cause this problem.

Change spark plugs and now car wont start.....1994 ford tarus


Do you have the "firing order" correct? In other words, is each spark plug wire going to the same cylinder it was on before you changed the plugs? If you have done nothing else but changed the plugs then this is the most likely problem.
If when you try to start the car it backfires through the exhaust or backfires through the intake. Then this " IS" the problem. Good luck.
