Did it run before?
Check to see if engine has fuel at carburetor and if it's getting spark at the spark plugs. If both fuel and spark are good then the problem could be with the timing settings or timing belt/chain is worn out/broken.
You change plugs because the continual sparking erodes the electrode, which slowly retards the ignition timing, which then makes the engine run inefficiently,
no the plugs just delivers the spark. you only need to do timing if u pull the distributor out of the block or do a timingChan or if the distributor slips
Your engine timing is off.
No. Ignition timing is totally controlled electronically, and changing plugs will not have a direct effect. You can always check it with a timing light if you want, but there's nothing to adjust.
By advancing or retarding the spark.
Does it have spark?, Compression? Timing?
That year does not have 1. The timing is computer controlled and you MUST have an engine scanner to set the timing on that engine. A timing light will not work.
Check engine compression Check engine timing
that's funny because I have a 350 Chevy engine that's is doing that as we speak.theres a few reasons it could be doing that. It could be something as simple as getting carb cleaner and cleanin your carb cause when it gets even a spec of dirt in there it can cause it to backfire.if that doesnt work try changing the spark plugs and if that doesnt work than you have a deeper problem which would be that your timing is off which is what wrong with mine.
An engine needs three things to run, fuel, timing, and spark. Check spark first (it's easiest) pull a plug and crank the engine. If spark isn't your problem check your fuel fiter, pump, etc... Fuel is the next most likely and easiest to fix. Good luck!
The timing for this engine is electronically controlled and not adjustable
