Re: wont idle, raw fuel out the exhaust, breaks up above 2 grand, 450s+crome
i KNOW its not the computer, ive put it in another car and it runs fine. the harness is right, xenocrons the man. fuel pump got put in tonight but i dont have much fuel in it so i dont want to run it long. im going to try to get it up to opperating temp tomorrow and see if it doesnt clear it up. i kinda wonder if it wasnt getting enough fuel pressure to keep it running right but it never went lean and never sounded like it actually hit a rev limiter it just spit and sputtered. if none of that works i got another dizzy that should be here in a few days to try. im in Greensboro NC if anyone is around this way and wants to come check it out one day and see if they have anything to add, just let me know. i appriciate it yall

i was going through ANOTHER pinpoint test last night and one step said "is the oil pressure warning light on?" it isnt... would this make it go into limp mode? it got late real quick on me so i didnt get a chance to finish going through it. but it said there could possibly be an open in a wire. if i get done with everything i need to tonight early im going to test those wires and see what i can come up with. if anyone ever had that cause it, let me know. thanks a lot yall later...

ECT really really ***** things up if you're throwing that code. Raw fuel, barely runs, white/grey smoke everywhere.
I just fixed a rotten ------- Integra that had a B20 installed in it, probably by monkeys. It was throwing ECT, IAT and TPS codes, which I *believe* all ground through the same pin on the ECU. I just ground them all off the valvecover, as the car is a wreck and the owner is annoying and calls me at all hours whining like a bitch. If it were my car, I would've run the wires back to the plugs properly.
Figure out the pins on the harness for the grounds + outputs for the ECT and go from there. Have you tried going through the diagnostics for an ECT sensor?

no i havnt, i never really put that much thought into it because it only come up on the OBD0 computer. it is a one wire sensor so i suppose it just reads resistance correct? i reckon i could check continuity in the wire back to the ecu and get a new one seeing as how it cant be more than 15 buck. hell i actually have one in another block ive got ill just try that one if there is continuity in the wire. the engine sat for over a year befor i pulled it out of the car i wrecked and finaly got it running...and i know what sitting does to ---- so ill try that.

OBD1/2 ECT is 2 wires, 5v input and ground. Check resistance across, and then voltage off the harness itself. The ECT sensor on the car was fine, wiring was fuxored.

you are correct sir! too bad i got pissed off at it befor i got it running right today. they did what you said and ran a wire to ground off the plug. there is another plug (the one i thought was right) that runs into the under hood fuse and splices into a green and red wire. i couldnt find it in any of my diagrams anywhere though. what confuses me is they cut the wire and ran the spliced wire back into the harness towards the engine not into the plug. idk guess i get to get back at it tomorrow...

well, i found the pin that the ECT goes to now and with the OBD0 pr4 i have no more codes and the check engine light goes off like it should "yes its fixed!" WRONG! with the obd1 ecus it still runs like *** IF it will start. on the distributer, i wired it up just like the paper xenocron sent me said and i have 2 extra wires...they dont go anywhere? i think its the cylinder id wires...the computer dont need that to run?

what management are you using? With a solid cell on my P28 its one of a few things. didnt remove checksums, didnt use P30 optionbyte hack, or i didnt disable the knock. if that doesnt help get a new wireharness and start from new
