94 Dakota 4x4 Won't Start

I have a 1994 Dakota 4x4, 5.2L. The truck will not start. This is what has been replaced as of today: Ignition Relay, Ignition switch, Pickup Coil, Crank Positioning Sensor, I have resodered the three red wires with a white stripe that are coming out of the black box and still the truck does not start.
The truck turns over, but has no spark to the coil and no power to the fuel pump.
I hotwired the fuel pump and the fuel pump works, but still I am not getting any fire to the coil. I have tried hot wiring the coil and still no spark.
Does anybody have any ideas on what else could be wrong with it that I haven't checked?

i have the same situation on a 92 3.9, works sometimes. if the check engine light comes on when you turn the key, it'll start, if it doesn't, it won't. new sbec and dist pickup, no change. can't pull engine codes, due to the cel not working most of the time.

Try the ASD relay...it powers both the coil and fuel pump.

had same problem with only start when check engine ligt was on. replaced the computer and that fixed it,

the daytime headights don't work but the headlights work fine when turned on. I'm assuming the relay needs replacing. Where is it in the truck. The haynes manual I have doesn't mention it

That's a 94 dodge dakota 2ws v8 5.2litre

where is the asd relay?

I had the same thing happen to me. I took it to the shop and there was a wire corroded and it was under the power distribution center. The fuse box under the hood. The other thing was the engine idiot light was not comming on either. You could not communicate with the computor. Truck would turn over great fuel pump work but it would not start. Fixed that broken wire and done. Hope that helps, it was what happened to my truck. 1994 Dakota 318 4X4 325,000 klm.

if it is not the relay or the crank position sensor or hall effect sensor then try the wiring under the relay box loosen relay box from fender open up wiring harness look for 2 red wires with fusible link remove link and re connect and soder then check 3 wires coming out of bottom of relay box possibly gray in color clip off old connection and re sodder then look for one blue wire that splices into 2 blue wires with yellow stripes check and fix connections should fix problems have a 92 that drove me crazy replaced everything still didn't start then did this and it started first crank good luck

I have the same problem with my dakota. The fuel pump will come on but then turn off, stalling the motor. Then the pump will not operate. Its seems to be intermittent. Any suggestions?

let me know what you come up with I have the same problem, I have checked the pump the shutdown relay and the fuel pump relay I hot wired the pump and it works fine.

My problem is my 93' dodge wont start when its too hot. When it does start and run, it dies when my oil gauge drops. Which is my other problem. My oil gauge drops ahen I put on my brakes to stop. Got any Ideas?

I have a 94 Dakota 4x4 with a 3.9. It quit on my way home from work. I have no power to the coil, fuel pump runs. I could find no bad wires or connections. Would a bad computer cause this? I need some help here, Thanks John

I had the same problem and found that the cluster of wires on the passenger side of the motor near the firewall had fallen on the exhaust manifold and fused together.

Still having the no starting problem....reconnected wires from fuse box, replaced coil, replaced pick-up in distributor, swapped out computer.....no change. Luv my truck but ready to use stick of dynomite!!!!

try replacing the camshaft position sensor,that's what was wrong with mine.
