What happens when you have the wrong firing order?

If you have the wrong leads going to the wrong spark plugs, then you will have a spark when the cylinder is somewhere other than where it should be, which is at the top of the compression stroke ready to drive the piston down and provide power. If you can start your car, it will be running very rough, have no real power at all and your gas mileage will be measured in gallons per mile. You are also running the risk of serious internal damage to the very expensive valves, so I suggest you fix it immediately.

Will a distributor spark if it is not in the correct position?

That's not really what's going on. The coil makes the spark, the distributor distributes the spark to the correct plug. If the distributor is not in the correct position, the spark does not go to the correct plug, or goes to the correct plug at the wrong time.

Won't start in damp weather 2003 dodge ram 2500 with 5.2 liter motor backfires?

Most likely you are in need of a tune up. When distributor caps and spark plug wires get old, they can leak and in wet or damp weather, the spark intended for one cylinder can jump to the wrong terminal under the cap or from one plug wire to an adjacent wire, sending spark to the wrong cylinder at the wrong time. If it won't start and it's dark,sometimes you can look under the hood and see the spark jumping around where it doesn't belong (to ground-the motor). Change the cap, rotor, wires, and plugs and you should be fine.

In any car, if you have a specific cylinder misfire, check the spark plug, spark plug wire, fuel injector, and compression. The computer could also have a problem. You will need to consult the detailed manufacturer's diagnostic chart for that, but the basics remain the same.

Dodge Caravan cylinder not firing?

First things to look at are your distributor cap and rotor, spark plug for that cylinder, and the spark plug wire to that cylinder. If you can't see anything physically wrong with any of those, try switching the spark plug with one from another cylinder, if the misfire moves to the new cylinder, you'll know the plug is bad. If it wasn't the plug, try switching the plug wire with another of the same or similar length, again, if the misfire moves to the new cylinder, you'll know the wire is bad. If that doesn't help, ask "What could cause misfire?" in the Ask box above or click on the link below to that question and answer. There is a lot of information about misfires there.

No fuel is getting to the cylinder, if there is good spark, assuming you checked the plug, wire and distrubitor. If spark is good right at the plug, then the intake valve is stuck shut.

You recently changed the spark plugs and plug wires on your 97 Explorer XLT 4x4 now you have no power and there is popping sounds coming from the engine you put the old plug wires back on and still sa?

Two of the wires are mixed up. The result is that two cylinders are attempting to fire at the wrong time. It can result in the popping sound when the cylinder fires at the wrong time.
