ok i have a problem. I just swapped a b18b1 96 integra motor. I am running OBD2B and running a b16 P2T ecu(sir ecu). Now i wanted to install the proper ecu into my car for this motor. Its a P75 OBD2B ecu from an integra. Now i know that i have to pin out the harness as connector A pin 16 on the civic is the fuel pump relay and on the integra its pin 15. I switched the pin for the ecu fuel pump kicks in but still will not start. Is there anything i am missing?

 

Hey Zeeman should be replying to the thread if not PM him... he knows his $h!t

 

check to make sure all of the engine/ecu grounds are hooked up properly.

If they are, check for spark and report back.

 

seems everything is working... but would anything else change on the ecu besides the fuel relay?

 

you're getting spark?

Did you pull a spark plug out and check for bright blue/white spark? Or are you just assuming that you're getting spark.

 

pulled a spark plug on my lunch. spark plug+screwdriver= spark lol

i am getting spark and still fuel pump kicks in....

 

sounds like you've got everything sorted out with the ecu.

What are you using for a dizzy?

Do you have the firing order set right?

It goes 4-3-2-1 on the engine with 4 being closest to the dizzy

and on the dizzy its

3 4
1 2



Do you have the TPS and MAP sensor plugs switched around?

Any CEL's?

 

ok will try that and get back to you.... the only thing i dont get is that with my b18 runs mint with my sir ecu. b16. but when i change to a integra ecu the pin changes and all i do is swap the pin

 

ohhhh....ok, I see what you're saying now.

Maybe test the LS ecu on another car and see if it even works.

 

ya the guy i bought it from is pretty reputable he said it was running a 2000 integra before he stripped it down. but i dont know anyone with obd2b to check it or an integra either

 

I dont want to be the one to say this but " pretty reputable " these days is NOT GOOD ENOUGH.
Find another car to test it on like Zeeman said.
