HELP? I have a 92 dodge Dakota 3.9 v6 it cranks over fine.
New Battery
New Coil
New wires
New plugs
New cap
New rotor
New Cam sensor
New plate
New computer... Still does same thing, cranks engine gets no spark!

When this happened, I was going down the highway, truck started bucking, back firing, and shut off. It started back up ,barley and I drove it home back firing and bucking 3 miles. I tried to start it the next morning, it cranks over but does not start... Please help good truck until this happened.

Please email me with any solution, [email protected] name is Dean... thanks for your time.

Wow, Deano! That's quite a list!
Was all that tested as "bad" or changed in attempt to fix?
At what point did you change the computer (ECM)? Any ECM programming done once installed?

Replace the Crankshaft Position Sensor.
