I have a 1990 dodge dakota sport with a 2.5 it stalls randomly and wont start until it sits for a few minutes. when it does die i still have fuel but no spark. all ignition parts have been replaced i.e. coil distributor plugs wires caps asd relay. vehicle does not have a crank sensor which is the only other thing i could think of. any help would be greatfully appreciated

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.

Yes you most likely have a ign module problem, the pickup hardly ever fails. If the truck is really hi miles repace the plug wires as well.

SOURCE: 1995 dodge dakota 2wd 3.9 no spark to plugs,or coil,orfuelpump

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.

SOURCE: Where is the asd relay on my 1990 dakota?

ASD is in the engine compartment fuse block.

The pump relay should be there also. Check your fuse panel in the truck though.

Fuses, Relays & Circuit Breakers The fuse panel box is to the right of the glove box with the glove box door opened or beneath the instrument panel (dashboard) on 1989-93 models.


Pull out the fuse panel for access to the blade type fuses
