Re: my 1993 dogde dakota would not start but it crank
Check primary voltage to ignition coil, engine cranking, dark green wire with orange tracer. Check the same wire at fuel injectors, that voltage comes from asd relay. I'm not saying the relay is faulty, check the crank sensor. Any applicable trouble codes?

In this video, I will show you how I fixed my 1992 Dodge Dakotanot starting. ... Engine cranks but won't start - Duration: 18:30. jimthecarguy ...
Engine Will Not Start Due to Blown Door Lock Fuse on Dodge Dakota ... cap and rotor, wires, plugs, coil, fuel pump assy, coil pickup sensor, crank position sensor and have new ECM on the way, Cranks but won't fire. ... 1990 Dodge Dakota.
Jan 22, 2009 - have a 1993 dodge dakota sport that wont start. when you turn the key on there is no power to the fuel pump and does not fire. any ideas ... I just bought a1990 Dodge Dakota Sport 4x4 5-Speed, there is only one problem, it only .... I went to move it the other day, it would turn over, but had no spark or gas.
What about spark plugs and plug wires on those two cylinders with no spark? This is a v8 engine, you didn't mention the other cylinders? The rotor turns when you crank it?
could very well be a faulty sensor, leaky vaccum hose, bad coil packs, needing of new fuel filter, spark plugs, wires.
Have you checked your fuel pressure to make sure it is good. You can do this with fuel pressure tester on the fuel rail.
Also check every cylinder for spark If you don't have any spark, or very weak spark, you could have bad coil pack, module, or crank sensor.
You can remove one plug at a time, and place it back on plug wire, place it on top of engine block, have someone else turn motor over well you observe to see if there is spark.
Do you have a service or check engine light on? If so, I would have the engine codes read to pinpoint exact problem area.
Let me know if you have any questions or need further help
First of all let's explain how the spark gets to the plugs. There is a crankshaft position sensor and a cam sensor. They are what determines when to fire the coils and injectors. The crank sensor is located on the passenger side on top of the bellhousing, the cam sensor is the pickup plate in the distributor. As the engin turns the send refernece pulses to the computer which grounds and ungrounds the ignition coil causing it to discharge and send voltager from the secondary coil wire to the center tower in the distributor cap. The rotor button recieves the voltage and distributes it to the 6 towers (1 for each cylinder) If you say you're getting spark from the rotor that tells me the primary side of the ignition system is working, and the secondary side is working into the distributor cap. I'd check for spark out of the plug wires at the plugs. Pull a wire and insert a #2 phillips screwdriver into it, hol the shaft of the screwdriver aprox 1/8"(no more) from the exaust manifold and observe the spark as someone turns over the engine. You should see a nice blue spark. If theres spark, spray a little gum cutter in the throttle body an crank it, if it fires you have a fuel problem. Install a fuel pressure gauge on the schrader valve on the fuel rail and observe it as you crank it. If theres no fuel pressure maks sure there's fuel in the tank, if so climb underneath and beat on the bottom of the tank with a rubber hammer, the pump may be going bad, sometimes you can jar them and make them run.
this maybe caused by no fuel or faulty fuel pump, ignition coil, wire and plug crank position sensor. first check for spark by removing on spark plug wire and put a spark plug in the spark plug wire boot, donot touch the plug only the boot have someone crank the car over. if you see spark, that part of the ignition is good. if not, check the coil resistance if should 40 to 80 ohm with a volt meter pf not replace. if ok, but no spark check the igniton control madule make sure the coil and module are receiving current. if not check the fuse that feels them. if it is ok, check distributor cap and rotor. if rotor and cap are fine, check for fuel at either the fuel filter, the fuel return line or removing some spark plug and see if they are wet. if there is no fuel check the fuel pump and the fuse and relay that control the pump. if there is fuel with high pressure but there is no spark, check the crank sensor for signal with a volt meter while cranking the vehicle
