I've got a 95 Dakota Sport with the 3.9L v6 engine. A few days ago it just sputtered to a stop and wouldn't crank again. I thought it was the fuel pump (had problems with it prior) so I replaced that. I also replaced the main computer (ECM or PCM. I'm not sure of the proper term.) I tried to crank and got nothing. It would spin but wouldn't even try to start. I've got pressure at the fuel rail but the plugs aren't wet so no fuel is going into the motor. I pulled one of the plugs out and it doesn't spark at all. Within the past 6 months, I've replaced the coil, distributor, rotor, plug wires, and plugs. It's been running fine but now it won't do anything. I read about the crankshaft position sensor and the crankcase position sensor and replaced both. I checked the voltage at the coil and going into the coil, there were 2 volts between the wires when cranking and nothing between either wire and either terminal on the battery. All the relays are good, but I've been seeing 3 positive terminals going into the relay and one negative. Is that how it's supposed to be? Could there be another sensor that's bad? The truck also doesn't show any codes whatsoever.
