    update, pulled intake, hooked up fuel pressure gauge, hooked up injector pulse test unit and bingo, 3 failed to pulse and one was intermittent with weak fuel pressure discharged volume. Remaining 4 discharge pressure drop were within 1.5 psi of each other. Fixing to send into injector clinic...

    achris / dubs thank for the 411 and attachments, will start running down lines and see where the glitch is if any, hopefully a wire and not a driver issue.

    finally all back together with fresh fuel, firing order and timing are spot on, fires right up. fuel pump replacement fixed low pressure problem now rock solid 38 at idle, jumps up to 43 when throttled up. now onto next problem, all four port side injectors confirmed not firing as was noted...

    correct, only 12. waiting on pressure gauge to show up to test fuel pump in conjunction with my vac gun to test against pressure reg and finally monitor system pressure while actually running and actually stumbling.

    yup, full signal contact from pcm to ect as when comes up on temp it drops out of closed loop yet will miss irrelevant if in closed or open loop.

    only code recorder were 14 and 12, 12 only indicates pcm is in diagnotic mode and communicating correctly, 14 is ect issue. Tested not found at fault but swapped out anyway. Erased codes, started, brought up to temps and through the rpms, still has miss regardless of rpm band, cold or warmed up...
