No Spark at Coil or Distributor 1994 Dakota V6 -3.9 litre
Truck ran perfect 3 days ago, parked it. then we had 3 days of heavy rain.
Rain finally stopped & went out to drive truck to hdwe store.
Wouldn't start, finally figured out no spark to coil (Orange & green wire).
Tried new pick up coil, New coil, still wouldn't start.
jumpered a wire from battery + to (orange & green) coil wire & truck started.
Want to fix it right, but retired & Limited budget.
Please help, Thanks

Welcome to DodgeForum!
Sound like the notorious power splice that provides power to the ASD and Fuel Pump relay, or just simply a bad ASD relay.
Try swapping the ASD and fuel pump relays and seeing if the problem persists. If it does, unwrap the wire splices around the power distribution center and look for a corroded connection.

Truck will not start- A common problem in the trucks, primarily ones made between 1993 Through 1995, was failure (corrosion) of the splice that feeds battery power to the automatic shutdown (ASD) and fuel pump relays. If these relays do not get battery power, your truck will not be able to start. This could also cause intermittent problems, or could possibly "kill" the truck when driving down the road. The splice is located underneath the Power Distribution Center (PDC), which is the black box located behind the battery. To Troubleshoot

Thanks , You have certainly given me a lot to check out & I will do so. One more Question:
How is the best way to remove that black relay box? Just Mark & cut wires at the bottom?
We have out of town In-laws coming this weekend & I will not be able to work on this until mon or tues, but I will definitively check out all you have given me & I will get back to the forum with my results.
Thank You very much

You don't need to actually remove the whole box, just unbolt it, shove it off to the side and track down the splices within the wiring harnesses.

Thanks to all posts
I changed the water pump and after i was done I had no spark and would not start. After getting on here I was able to track down the culprit. Wires under the main fuse block in the engine compartment corroded apart. Thanks to all of you who work on these trucks and have took the time to post your knowledge for the rest of us.

1994 Dakota 3.9L Auto, 113K Miles
Truck has been parked in the guys garage for the last 6 months or so, he was just taking it out every now and then and driving it around the block for his daughter who he is planning on giving the truck too. He took it around the block, parked it and about a week or two later, went out and it acted like the battery was dead. He replaced the battery but the truck would not start. Now I am trying to help him out and getting it running again for him.
Battery is fully charged, cap and rotor has been changed. Plug wires (were shot) replaced, coil ohmed out very strange, replaced it with new one (yes, I have checked it and it is good)
Relays, All relays are working with no issues, have swapped the ASD relay and it is fine.
Pulled apart all the wiring from the Relay box up to the firewall and have inspected and traced each wire, all looked good.
Replaced the Crank Shaft pickup on the back of the engine.
Getting no voltage to the coil
Have pulled and inspected the connection to the computer (60 Pin) and again, no issues.
Been reading everything on what people have been having problems with on the Dakotas and now stuck with no easy solutions. Any suggestions would help.
