Your car backfires when you need a new transmission,or tune up. How do you know the difference? Simple...if your car backfires then wont start, or wont start and then backfires,you need a transmission. If it backfires, and then starts moments after, you need a tune-up. Glad to help...David
It has either . jumped timing
Timing is off.
Possibly the firing order got messed up.
Valve timing off, timing chain jump.
its half a turn out of time. plug fouled install a new spark plug
Get a new battery, Auto parts stores sell them.
Valve adjustment isnt right
First check for fire at any of the sparkplugs and if you have spark then check your fuel pressure and if its not within specs then replace the pump.
Check the crankshaft sensor. Also check the timing and timing belt. The backfiring indicates that the engine is firing at the wrong time.
sounds like pluged catalitic converter or egr valve
You don't NEED it exactly its just a fancy box that connect your battery wires to the starter. If your lawnmower is clicking/wont start or silent when you turn the key its possible its the solenoid. undo the rubber covers from the solenoid touch the two bolts together using something metal and start it up, bam. you just by-passed the solenoid. (the solenoid will be next to the starter in most cases and have two rubber wire covers on them)
