Truck was running fine and then died one night. Luckily, I was very close to home and coasted there. I'm pretty confident this is an ignition issue because when trying to crank it, I can smell fuel from the engine. I have replaced the ignition switch, battery, plugs, wires, cap, rotor, coil, and module (or whatever the part is inside the distributor). I also replaced the fuel filter recently. The starter cranks like normal but the engine won't fire up. 88 Dakota with the 3.9 v6. I'm out of ideas, maybe this is something you guys have run across and can shed some light on. Thanks.

 

Did you check the splice under the power distribution center? Check FAQ for the location. 88 is a ways back though, but I think you still have it.

Do you have fuel pressure?

Do you have spark?

And I think the rotor inside the distributor cap is what you were refering to.

 

like dbilik said, check the splice for the ASD relay and the relay its self, thats probably it
