Picked up this truck cheap I now know why . Yet I still move forward to repair .
Prior mechanic sabotaged wiring and who knows all .
Please schematic any one please

Thanks I do appreciate any and all help

 

You should note that the pcm pulses the ground to the cops and injectors. 12vdc positive is standing on them with key on . The pcm controls the firing and start signal if pats security is not satisfied none of this will work . The crank sensor sends a signal to pcm so it knows the position of the crank , the cam sensors tells where the cams are at , the pcm controls the vcts which pulse dirty engine oil to phasors to hydraulically adjust cams where pcm wants them . Low oil pressure can mess this all up . Factory pump is marginal ,plastic chain tensioners tend to blow gaskets and lower oil pressure . Broken plastic chain guides get ground up and block oil flow in oil pickup . Failure to change oil often leads to sludge and blockage ,engine has small passages . I do an engine flush every other oil change less than 5k miles. Short trips in cold weather does not remove condensation from crank case .

 

How long would engine need to run? I have a 7 mile trip to work, but with 7 red lights, its 15-20 minutes to work, long enuff?
