You need to determine if the Cam Position sensor is bad.
You also need to test the MAP (Mass Airflow Position sensor is bad as well. If its backfiring then I would think it is the Cam position sensor. I can't tell you where it is because it's different on each model. Refer to a Clinton service manual for its location or call a dealer.
Wish I could give you more info.
SOURCE: Replced the cap & dist coil pac has fire no spark to spark plug
install the new rotor, if that isn't it check the crankshaft position sensor.

pull one of the plugs out leave the plug wire on it and rest it on something metal on the car and have someone try to turn it over.if no spark can be seen try changing your crankshaft sensor
SOURCE: no spark to plugs or coil.
Do you have power to the coil with the key in the run position and when cranking? (ignition switch)

I have seen this before working for Ford...it really came down to removing the exhaust pipe infront of the clogged catalytic convertor and road testing it to confirm that the convertor was clogged.. So if you can loosen the pipe in fron of the convertor so that the exhaust can escape with out going through a possibly clogged or melted convertor and if it runs with power thats great other wise diagnostics for the engine will be needed to be done.
