Just put in a new Gs-r motor in my integra bc my friend messed up the other one.... Long story.


But the car will not start right up unless given gas and will not stay idle. The same gas from october 31st, 2008 is still in the tank. I have replaced the pcv valve, and fuel filter and spark plugs. Not really any change. The car was obd2 but now has obd1 in it. I have a conversion harness and its running on a JDM Obd1 p72. So is the fact that the computer is JDM and the motor is not the problem, or is it the gas? Or could it be something else. Could someone please give me some ideas

 

Try another OBD1 ECU. Also, do a compression test. Any CEL?

 

so you think the gas has nothing to do with it

 

im sorry... CEL? lol

 

check engine light... CEL

i think he's assuming that you've done the normal checks. spark fuel etc. thermal know's his shit... i know first hand.

also... october isnt that long. once you get up over 4 months u might have trouble, but mine sat almost a year and started right up.

 

nope its not throwing any codes....The only thing left is for me to put gas in it with the fuel injector cleaner... bought a bunch of shit to try and none of it worked.... I dunno, i just need this fixed

 

MAP sensor?

Had the same problem when i accidently kicked mine loose.

 

sometimes with the obd1 ecu the map and tps can be switched and still not throw a cel due to the same 5volt reference needed. try switching your map and tps plugs and see if that fixes it. if not pm me

 

Another thing is the car has a horrible miss. Friends said when i drove buy sounded like I was ridin on 3 cylinders.

 

okay this is weird.... or maybe im that dumb... um, Okay the new motor I put in is a 95 gsr, obd1, the old one is obd2b.... everyone said my old obd2 p72 wouldnt work... I tried it anyway and it starts up just fine, still has a slight idle problem but is a tiny bit better. Is it safe to continue using the obd2b computer?
