Ok 97 2500 with 5.7 auto ext cab lwb. Got it with an o2 code and knock sensor code. Changed both and still a little rough but ran and drove. Decided to upgrade Injector to multiport, Pulled lower manifold to clean as it had tons of carbon build up. Upon installation I noticed the distributor gear was warn so I replaced with new metal distributor. Full tune up plugs coil cap rotor fuel filter. Fuel pressure was at low 50s so decided to replace fuel pump. Was given bad advise and reset computer by removing battery terminals and touching for a short period of time. Now I have a no start it just starts and dies immediately. There is no security light, not even a bulb. CEL is p1375 I think. Adjusting distributor 1 tooth either way makes it worse. Noticed door jamb switch was busted so I replaced (here is the odd part) now no CEL not even during initial bulb check so I removed it. Finally got to idle halfway smooth but falls flat on face at the touch of throttle. No vacuum leaks. STFT b1 and b2 are at 50 and LTFT read 25. Any ideas on this on. Thanks for any help you can offer.
