I can't find wiring diagrams for your truck..... (last I checked, my favorite site was down, and even the ones they did have previously just weren't that much help.) Getting a service manual for your truck would be a great idea. Then see where the injectors/coils draw power from, and start following the circuit.

 

I found this. so if all the injectors, coils get power from the same source and only one side is working and i traced the injector and coil wires back to the pcm plug im confused lol

PCM provides ground path, check the splices where the wire splits and runs off to the different coils/injectors.

Splice 162 looks like a likely candidate.

 

Another issue, im also not getting any power to bank 1 of the o2 sensors both bank 1 sensor 1 and bank 1 sensor 2. Are they all interconnected also? thank you will check for broken splice tomorrow hopefully.

 

That I don't know......

 

Ok i got another question regarding where the power comes from for the coils and the injectors, i have ground coming to all injectors and coils but just no power to the left bank, ive pulled most of the wiring harness and cleaned the fuse box from underneath by unplugging and using electrical spray and plugging back in.. Thanks.

 

They all get power from a common source. There are a couple splices where the wires break out to one side of the engine, or the other, and to the individual injectors/coils. I would bet real money that one of those splices is where your problem is.

 

Looking at your dropbox schematic, connections S137 and S155 might be a place to start ?

 

Truth be told I'm not very good at reading schematics, so those locations mean very little to me. I have the left side of the harness pulled already will check those splices.

 

I hate electrical problems. They are usually a major pain, with much gnashing of teeth involved.....
