Everyone,

I need your help...I have a 90 Honda CRX dx with a LS swap....LSD trans...

I have hand build engine, t4 turbo kit, 550cc Fuel injectors, walbro 255 fuel pump, AEM wideban 02 sensor, apexi safc2, complete msd ignition system and PR3 ECU...

MY problem is that my car doesn't start right, I need to spray started fluid on the Bov for it to start....Injectors 3 & 4 stay open, really rich, injector 1 & 2 Stay lean, dry.....Do I have to change the wiring of my car??? and if so to what?

I was told to change my motor wiring to 90 honda civic si.....Is that what I need to do???? How about the wiring behind the firewall to the ecu??? What ECU should I bee using...

Please let me know your suggestions....

Thanks

 

sounds to me like you got saturated injectors and you still got the resister pack hooked up you can loop them and solder the wires and i bet it will work of if your confused take it to a shop before you buy all these parts you dont need

 

Was the conversion to MPFI done by yourself??? I'd go back over the wiring....and I'd say you should be using either an Obd-0 Integra ECU (PR4) or an Si ECU..

Are you throwing any Codes?? If so which ones??

 

Nope, No codes. I been using obd 0.

I have not found any shop that are willing to look into my car...There's not that many performance shops here in Chicago, IL...I been doing everything my self and a friend.

I really don't know what to do next, I am thinking in getting the complete ecu and engine bay wiring for a 91 LS, but I haven't had any luck finding it...

 

just post in the marketplace. someone is bound to find you a good deal

 

Can you please give me a hand on that...I'm not familiar with this site...

Thanks

I was able to buy a engine/ecu harness....Will put it on this weekend...I hope it works better...Should I stay with the pr3 or get a pr4?
