First off i wanna thank all the guys for the motivation , advice and help in getting !y engine swap done. Im having codes p01860 tcc solenoid circuit electrucal....p0300 engine misfire....tps insuffucent avtivity...all those 3 x2. Now i did rewire the 5v reference to the tps and map sensor but circuit is not broken i can see clearly the wire. I havnt touched the tcc but i did rewire all the blue pin56 sensor grounds all together to make sure the pcm grounds them and that i did not ground them straight to block the tps,ect,map, the nonpresent iat, ac sensor ground and tcc "m" ...all these i disconnected and reconnected them via pin 56 blue ...was this code thrown cause i undid them? I dont know how to clear codes on my new scanner. Also my car wouldnt run without a brief step on acc pedal once i did that it ran like a beast...any ideas oh yall great gurus?

TPS sensor messes with a ton of things, I'd definitely get that sorted out first. P300 is random miss but the TPS can have a hand in that. Can't help you that much more than that.

I cant help with how to reset your codes on your scanner, but usually its just "clear trouble codes?" then confirm......I do know all those sensors have individual grouns from the PCM and Im not sure how running them all to one pin would effect things.

Give me a few and I will take screenshots of my wiring guide and post it here.

C2 pin 3 is giving you a ground signal when the engine is running? Ive never seen that, It should give a +signal for 3 seconds or so when you first turn the key, then again once the engine starts. Make sure your relay is good also.

If you tried wiring the output of the PCM directly to the fuel pump you most likely burned out the driver transistor for the fuel pump circuit. So if you did do that....
Other than that as above check to make sure your wire is in the correct location on the right PCM connector.
