You may have a plugged fuel filter as you don`t say if you have changed it. also have your fuel pressure tested with a gage, it should run about 36 lbs pressure if its multi-point fuel injection or run at about 15/18 lbs pressure if its a throttle body.

SOURCE: changed water pump on 1994 dodge dakota sport

I have a 94 dodge dakota sport 5spd. I had that same problem recently. Thought it was the pickup coil, so I changed it and my truck would still not start. And the rotor and there was still nothing. Then I changed the Crank Sensor and THAT was why it wouldn't turn over.

SOURCE: 1998 dodge ram pickup 318 eng.

If the engine seems to run fine over 1450 RPM maybe there is a vacuum hose leaking or EGR valve is slightly stuck open. Any help from the OBD II trouble codes? Or is there simply no MIL and no stored information in the OBD II computer read at the local parts store through the connector by the drivers knee?

check your catalytic converter for clogged up.
disconnect the exhaust pipe before the cat and run the engine to see if it still cut off.
if it run better, then that's the problem

Dodge dakota backfire

It sounds like you need a good tune-up, such as spark plugs and/or wires. They will act up when cold and when warmed by engine temperature will let the engine run smoothly again. And possibly a distributor cap/rotor.

I have a 98 S10 pickup 2.2L. Engine has a bad misfire and no check engine light.

Improper spark plug gap
Damaged spark plugs
Poor contact between wires and spark plug or cap or coil pack
Bad insulation on plug wires
Cracks or corrosion build up on cap and rotor
Weak or defective coil(s)
Weak or defective ignition module
Weak or dirty crank sensor
Timing
Fuel pressure (from pump)
Clogged fuel filter
Defective injectors
Vacuum leaks
Defective injector drivers (computer)
Poor compression

That is all I can think may causes engine to misfire.

I have a 2003 dodge dakota slt 4wd it is missing has no power and is backfireing we put new plug wires dtistruboter cap plugs crank sensor

you should also check your rotor, magnetic pickup and coil for problems or brake down if they check out ok you need to remove the valve covers and role the engine over with the coil unhooked and watch the rocker arms carefully for travel as you may have a camshaft problem

How about the pick up coil in the distributor? A trick we used to use back in the day was to tap the distributor housing with a hammer, key word tap. If the engine missed or stalled than the pick-up coil was replaced.

you can check for spark by plugging in one of your old sparkplugs to one of the spark plug cables and letting the sparkplug lay on the bare metal of the engine. Turn over engine to see if the spark plug is producing a spark. No spark? Check under the distributor cap, take a look at the rotor for damage.

The check engine light is on and the diagnostic code is 43, on my dodge dakota 1997, 3.9L. Engine is weak and misfire. Check spark plugs (OK)and everything else there is. Am I missing something? What?...

Plugs need to be changed every 30K, and wires, cap, rotor every 60K. Could be a weak coil not putting out enough spark, could be the pickup in the distributor, could be timing is off from stretched timing chain, could be weak compression. Check the basics first.

We replaced the crank sensor and cam sensor on a new 5.2 engine in a 1998 Dodge Durango. We checked and rechecked the connections and still no spark.

check the wiring harness at the coil,sometimes that plug will get loose or dirty resulting in a no spark.
The only ign system parts are the crank sensor,cam sensor,dist,dist cap,rotor,spark plugs,wires,and coil,and the ecm which controls all of these,is there a check engine light on?
run a scan tool to check for stored codes or system events stored in the ecm.
