Customer Question

01 ram 2500 5.9l gas motor. keep getting p1391 code for intermittent crank or cam.pulled crank sensor and saw that it was hitting the fly wheel bc the rust built up on the block behind it. so I got a new sensor and cleaned as much rust away as possible. also cleaned off the whole tone plate with sandpaper. truck has new battery, plugs, wires, distributor, cap, and rotor. also has new cam sensor. new intake gaskets. I have greats fuel pressure and plenty of spark from the coil. I have the fuel sync asclose to 0 aS possible. I can not read which cylinders are mis firing bc the crank sensor problem.

Hi, My name is ***** ***** for the delay.

I will do my best to assist you

the truck does start and run now?right?

please explain the question

thanks

Customer: replied 1 year ago.

the truck will idle and run. runs a little rough. I can rev it up and it will idle back down fine. I need to fix this code but I don't know whats causing it. and im assuming the problem is the same reason it runs a little rough. in the trouble shooting part of my scanner it says some stuff about the pcm using crank signals to detect misfires and when I go into the misfire section, it shows 0 misfires on any cylinder, when I knoew its missing bc I can feel it. also it has a new pcm

Expert:  tims auto repair replied 1 year ago.
