First place to check is what you have done . Check for the correct firing order of the plug leads as it is possible to cross 2 wires. Next make sure that the leads are not touching each other as this will cause cross over and fire the wrong plug. Next check the sensor position as there is an air gap to the rotor that has to be correct. Check that the sensor is tight and that there is no dirt in the air gap. check that the wires are properly connected . Lastly run the fault codes to determine if something else is not causing the problems.

    Before the car broke down completely it would only start when it wanted to like if I shut it off I would end up having to wait like an hour before it started again. I thought it was just the sparkplugs because they looked really bad and black like they never got changed so I had those changed then after that it started cutting off on its own while idling. Then after that I was having trouble getting it to start one day at work and it finally did so I was on my way home and the car made some really bad sounding noises, the oil light came on and I had to be towed back home. The car is a 1996 Monte Carlo LS with 138,000 miles on it. My father in law suggested we changed the crankshaft position sensor and we did that too. I really need to get the car to a mechanic but would like to know if anyone knows what the problem is right off. Also, since it broke down and wouldn't start back up it is able to start but only up to 30 seconds tops if we're really lucky and the engine basically sounds really loud like some huge piece of equipment running and the oil light is still on. Oil level is good but is a bit dark.

    My wife says it ran longer than 30 seconds before like 3 minutes or so which is a big improvement over the 1-2 seconds it only started before stalling before lol

    I am reading about a massive recall for chev product ignition switches being faulty and shutting down when ever. May be you should concentrate on the switch to see if the problem originates there.

96 Dodge Dakota V6 replace the camshaft and crankshaft positioning sensors and when it runs it runs good but it goes to acting up and backfires then if it does that it will not start for nothing

Did this problem start after these sensors were replaced or were these sensors replaced to possibly correct the problem you are experiencing? The back firing may be the result of low fuel pressure indicating the fuel pump is weak/getting bad. I would suggest having the fuel pressure tested when the vehicle is in the backfiring/no start mode. Sounds as if the fuel pump may be a problem

Start sounds like its smacking the flywheel

A broken starter, 99.9% of the time, is caused by an engine backfire. Whatever caused the backfire is what ruined your spark plugs. From my experience, the most common culprit would be a bad crankshaft position sensor.

My 2001 dodge durango dies right down when started even hot or cold it back fires i have changed the sensors it does this in open loop to closed loop

Backfiring is a great symptom because you know what the problem is right away. It seems to be a timing issue. Crankshaft positioning sensor, distributor, electronic ignition, etc. Diagnose your problem concentrating on anything to do with timing. Vehicle just don't just don't jump timing unless something goes wrong of someone does work to it recently. If it backfires from the the exhaust you timing is advance and if it backfires from the intake it's retarded. It's is your firing timing.
