Ok finally got it back to the house and pulled the codes. First it starts and runs but stumbles bad even in nuetral. Ok first time i read the codes i erased them all then started the truck and had to move it to another spot to be able to look at it. All the same codes came back again a total of 9 of them!!!
1. p0340 camshaft position sensor
2. p1747 epc solenoid short circuti
3. p0755 shift solenoid b
4. p0743 torque converter clutch circuit
5. p0443 evaporative emission system purge valve control circuit
6. p1451 evap emission control system vent control circuit
7. p0135 o2 sensor heater circuit bank 1 sensor 1
8. p0155 o2 sensor heater
9. p149 egr vacum solenoid circuit

Im guessing all these tie together some where or possibly in a harness and maybe just maybe squireels got to that harness but im not seeing anything at the moment looking at the harneses in the engine compartment and under the truck.
Any idea other places to look getting ready just to follow the wiring and see what i can see, any other ideas? maybe a main ground that ties these systems together possibly? I dont have a manual on this truck so i dont have the schematic for it either of the electrical system to be able to look if these tie together somehow. With all these codes i dont think its the transmission like i originally though but a short somewhere or eaten up wires. Also if it helps the on/off light for the overdrive flashes constantly
thanks for any help

 

I would for sure check all the grounds. Could be the ECM is going south and either not grounding or lost a volt reference.

 

Really need to know where the grounds are and what the voltage should be and where. This started suddenly going down the road without any warning at all. Hoping someone has seen this before or at least knows where to start on it. Only vehicle i have so need to get it fixed asap
thanks

 

What is the condition of the battery ? ( voltage, load test, cable condition, connector condition, etc )

 

All good on the connections and connectors, few months back i cleaned them up just for pm and then sprayed the terminals down with a protector we used where i used to work. Ill have to check the voltage and the load test results

 

Ok checked all connections and cleaned again to be sure all is ok.
Alt putting out 14.4 at idle
Battery holding 12.28 with engine off
Did a crank test and only drops to 11.1 during cranking

 

12.28 is a low battery. Not too sure if charging it would help, or if the battery needs to be replaced.

Not sure what the crank test is, that is not a load test.

 

CRank test is basically a small load test lol, putting the multi meter on the terminals and see what the voltage goes down to while trying to start the vehicle, has worked in the past when no battery tester was available, normally we would change batteries when the voltage would go below 10 volts on a crank test. Starter draws a lot of amps so if a battery is getting weak it would show on a crank test as we called it.

 

You don't have a ground circuit problem, you have a power distribution problem

Check fuse F23 in the under-hood fuse box first.

 

Thanks for all who responded fuse was the problem on it. Strange though the fuse showed proper voltage on one side and the other side was 3 volts lol. Replaced it and runs like it did before. Looking at the fuse it was broke on the u part of it and it fell against the other part making partial contact with it.
Thanks again

 

Keep an eye on it (and a few spare fuses in the glovebox). If the problem comes back, you'll have to figure out where the intermittent short-circuit-to-ground is at.

Most common is for the O2 sensor harnesses to get onto the exhaust, melt the insulation and short out the heater power circuit. If a 4x4, also check for the harness contacting the front half-shafts.
