Okay, and I can't find mention of it in the thread, did you try another ECU? I'd be inclined to try another harness and ECU despite test previous results.

yes i have 2 computers. it does the same thing with both.
i would love to try another harness but i need to find one first. today i cut off the cps plugs to put on the new weather pack ones and the wires on the harness side all have corrosion (green crap) inside of them under the insulation. i was unable to install the other side of the new plug due to i grabbed the wrong harness prongs. so Tuesday hopefully will have them on.

still no difference with the new plug on the cps....
does this make sense to anyone else...if the wires are corroded the ecu would might not be getting the correct number of pulses from the cps causing the ecu to cut injector pulse? i wish i could find out what the ecu is seeing.

I thought the ECU monitors three signals as a part of the equation you're talking about: IGt, IGf and IG- Unless they're all screwing up in harmony a code is bound to show up.... I could be wrong completely wrong though, I haven't had the pleasure of working with a TCCS where simply swapping out components as a last ditch effort didn't cure it. I would replace the wires along with the connectors. Corroded wire has a higher resistance too.
