Your timing is off or you have crossed the plug wires somewhere. Double check that all your plug wires are properly connected and are connected in the correct order to the distributor then double check the timing of the engine.

You have the plug wires on wrong. It is firing when the intake valves are open.

03 beetle 2.0 ran out of gas and car wont start and backfires
Possible that it has sucked water and sediment off bottom of tank causing a lean backfire no start. Have you tried spraying carb cleaner into the throttle body to see if it tries to run on that ? As Ray said it is possible timing jumped.

After replacing my intake manifold and carburetor my engine wont start, only sometimes but it would sound ugly and run very roughly at 400 rpm. PLEASE HELP
You have leaks in your gaskets. or vacuum lines removed and not replaced or broken in the operation. trace air leaks with propane torch unlit. where engine speed increases, you have an air or vacuum leak.

The first thing to check is the ignition timing then the spark plug gaps. There are specific settings/size for the above and must be correct for the car to run smoothly.

HEVROLET BLAZER 2000 MISFIRING
Timing is off,problem with timing chain,also check fluids in ******,plus also if you have a distributer in your vehicle,if it is cracked,moisture getting in and ruining the points,-that is if your vehicle has a distributer! This will make a vehicle run rough as well.
You can have new plugs put in,but if your spark plug wires are cracked or worn,this will also creat misfire and backfiring.

Hesitation and backfiring
sounds like maybe you have some trash in your fuel tank. Try changing the fuel filter and cleaning the carb. If the problem persists, you may have to drop the fuel tank and have it cleaned out.
