I replaced the injector cups installed new injectors cranked profusely. After several times the truck started running like a champ, revs and sounds good. I put valve covers on hooked up everything started right up no problem, this time I fill the radiator and everything seems great however as I suspect the engine light is on so I turned the truck off hook up my craftsman scanner got several codes hit the erase button and the truck has not even pretended it was going to start since. I have tried fuses IDM ipc cps ebpv and countless other, I bought AE and ran every test I read up on the buzz test sounds better than my running truck and from what I can tell it is reaching all of the parameters for starting_rpm's high pressure oil fuel pressure. Any advice would be greatly appreciated
