1991 Dodge Dakota fuel pump wireing. I removed pump and tested OK- Tried switching relays (all same in relay box) Still no cycling only a slight noise then silent. Ran 12-v (spiced) to left wire of 5.


engine cranking do you have spark at the plugs and fuel injector pulse? I don't know what testing you have done? I am trying to decide if more than one issue? Did you check voltage and ground at fuel pump connector, engine cranking? Initial prime is one thing but after that, if no rpm signal, no spark--no fuel injector pulse--no fuel pump. W/o rpm signal computer won't ground the asd relay. Any applicable trouble codes?
In my opinion, you can't bench test a fuel pump, I've seen faulty fuel pumps that would run up a storm on the bench but make no pressure when in the gas tank.

check for spark, no spark, no fire engine wont run, possible bad ignition coil, wire from coil to distributor cap, no power to ignition coil from ignition switch (rare) wire broken to ignition coil (even rarer)

My 1991 dodge dakota v6 2 barrel is using way to much gas 150mi per 16 gal tank what is the cause


check for fuel leaks. from the gas tank, to the fuel lines, to the carb. i assume its an electronic throttle body 2 barrel. i have seen those leak internaly from the inside of the carb/throttle body causing exsess fuel to be used. you could also have a very bad fuel/air ratio going on there. could be bad o2 sensors. but i would start with the leaking fuel first.

1996 dodge dakota 3.9 engine quit running when we do the ignition test it gives us a code of 1255 what would that mean. It will run if we put gas down the carb.


i`m not sure what the code meaning is but if you put gas down the throttle body and it runs then you have a fuel problem which this code may refer to.this year of truck is fuel injected throttle body.it could be a fuse,fuel pump relay,fuel pump,plugged fuel filter,stuck open fuel pressure regulator not building enough pressure,wiring for fuel or pump system or even a computer(ecm) problem.

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.

No spark or fuel 1991 dodge dakota even if i hot wire the coil no spark i hot wired the fuel pump got gas to throttle body but when you give it full throddl no gas to moter.


I know it's a long shot without looking at it or more information. Look under the hood on the left (drivers) side center of the fender at the wire harness. The one inch diameter or so wire harness running along the fender. Look for any green spots or even open the harness up a bit to look. The ASD relay wire runs through that harness. I've found a few corroded in two with the same symptoms. I think the washer bottle may be over the harness, not sure. Like I said, it's a long shot. I hope this helps.
