I have a 2000 dodge Dakota with the 5.9 v8 my ecu was not reading to my obd2 scanner so I replaced the ecu now that I have done that it sill wont start my fuel pump is priming and my spark plugs are wet I have spark on cylinders 1 and 3 but no spark to 2 and 4 I just replaced my cap rotor and pick up coil any ideas on what could cause this?

go to Didgeforums.com.

I had a similiar problem, found the solution there. It was the wiring harnes on the drivers side under the hood, just above the wheel well. there are a cluster of wires in a bundle. I unpacked the bundle carefuly and sure enough the were two or three wires all coroded, had wite powder from corosion. repaired the connections and bingo. I posted details at dodgeforums.com. browse around there. I posted pictures as well. this is a common problem.

SOURCE: 86 dodge 250 v8-318 no fire at spark plug, will not start

did you change the main coil and coil wire?if so then check the ing resistor and then the computor box

I WOULD SAY IT IS THE COMPUTER {BRAIN} THAT IS WHAT SENDS THE FIREING ORDER AND VOLTAGE AND SETS THE TIMEING SPECK I WOULD SAY CHECK THE COMP

P0038 typically indicates O2 sensor failure or possible grounding out if the cabling to it has failed. Start with that as it is easier to replace than all the plugs/coils etc. Reset the code and cross your fingers.

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.
