I rebuilt the engine in September 2012. Around the end of January 2013 it started dying randomly for about 2 weeks and then started throwing random check engine codes. I have since replaced the computer, the idle control sensor, throttle position sensor, map sensor, plugs, wires, cap, coil, rotor bug, upstream and downstream 02 sensors, crank shaft position sensor, cam shaft position sensor, injectors, fuel pump, vehicle speed sensor in the transmission and in the rear-end, altenator, battery, catalytic converter, muffler, re-wired the computer plugs cuz the locks were broke, and im still getting codes p0320, p0351, p1391, p0171. Im aware water these codes are but can't figure out how to correct them. And my truck randomly stalls and backfire bad has anyone ever had this much trouble

 

Lets recap.

0171 = bank 1 lean
1391 = cam or crank signal intermittent
0351 = ignition system not sensing full load on coil primaries
0320 = crank sensor failure

first off, have you checked out the wiring harness and looked for loose connections? What about in the connectors?

0320 and 1391 are both for the mechanical timing system, sounds like the sensor set is either missing/has a broken power or ground line. It sounds like you've replaced all the sensors, so I would start looking at the wiring harness and PCM connectors.

0351 occurs when the coil primary windings become damaged or an aftermarket ignition is connected across the factory coil contacts. The PCM expects a certain current draw to charge the primary windings, and throws this code when that minimum is not reached.

Bank 1 lean is just that- it's lean.

 

Welcome to the forum Karoon.

I moved your thread to the proper forum.

As Magnet says, give the cam/crank sensors a very good look.

 

Wat do you mean magnet? About the primary windings the only thing i did was replace the coil and replaced connector i replaced the pcm connectors and then put hose clamps on the pcm connectors bcuz my truck kept dying and backfireing it was due to normal road vibration rattling the connectors it would be nice to talk over the phone bcuz none where i live knows ship about dodge if u would plz contact me xxx-xxx-xxxx

 

I have checked everything unless the wire is broke somewhere in the wiring harness which ill never know how to find. I cannot buy even a used harness around here. An wat is really strange is all these codes except the p0171 have just started randomly and its got me confused if i did something wrong or something has finally went wrong. And my lean code the p0171 i don't know which side is running lean bcuz i have single exhaust both banks run into one pipe or y its doing it bcuz i have no air leaks no vacuum leaks my exhaust system is replaced that's y it'd b easier and more helpful if i could talk to you over the phone i need help that bad i have dropped near $13,000 into this truck to just get rid of it im not taking that kind of loss on my wallet or my pride

 

Were do you live I ask because some rodents love eating wire the coverings that is seen it a number of times.

Inspect every inch of your wiring only other thing could be it some how got damaged/melted so on.

Have you done anything to the wiring like install a radio or a security system?

Think back when did this start happening?

 

I don't know which bank is bank 1. I want to say driver side. The O2 sensors determine the lean/rich status.

 

Bank 1 is drivers side. It follows spark plug #1.

 

I know bank 1 is drivers side but my exhaust is both exhaust manifold run into one pipe it has 02 sensor at the y in front of the cat an an 02 sensor behind the cat so technically the code reader telling me bank one is lean doesn't mean its right cuz the front 02 reads both sides so im lost there
