Re: changed spark plugs and wires now car wont start
I know this might be obvious but the obvious is often the problem. Did you replace the coil wire that goes from your coil to the distributor cap? Also, double check to be sure that your wires are connected in the correct order. A little more clarification might help. Does it turn over? Does it just click? When you turn the ignition key then let off does the car clunk or make a wheezing sound?

The mechanic should check on the ignition system first . Check the ignition switch, the ignition coil , the spark plug , the spark plug cable , the distributor assembly and the wires and the fuses.Check if there are worn out or destroyed then replace it. And then set the distributor timing mark and the firing order of the spark plug which is 1,3,4,2.These 1,3,4,2 are the number of the spark plug connecting to the distributor assembly.Then try to start the engine .The cause of the engine back fire is ignition timing not in order.
On v-6 it is in the front, tight working area. unplug wiring, remove spark plug wires(mark them for proper order for assembly) unbolt from engine coil packs and remove module, install module(with a little diealetric) and reverse for install.
Johnny, It's probably the coil pack. If you follow the spark plug wires backwards from the plugs it will lead you to the part(s). There may be more than one. Check with the local autoparts place to see if they can test it for you. If not I would try a Junk yard first, incase that isn't the problem.
Sounds like a ignition control module failure. Check for spark at a spark plug wire. No spark then suspect module failure. Good spark-- Suspect possible fuel delivery problem. If spark is good then fuel pump may have failed.
