ok so i got a b18b swap converted to obd0 in my 88 crx si the only code is 4 long and 3 short then repeats i heard ist a fuel problem but not sure it has stock pump and fpr please help fast

 

43 is the fuel pump. I have seen alot of people with LS swaps get this code. My only advice is try clearing the codes and see if it goes away. Does the car run?

 

yes runs good not awesome ecu is weak comparred to the 94 cpu that is supose to be yousing

 

what ecu are you using now?

more than likely you have the OEM pump and FPR... i would run through a helms and see what they say to test for when getting that code...

sorry i can't help more.

may be a bad o2 setting it off... after search google some other people were given that suggestion as well.

you may want to PM the topic starter from that link and ask if it was solved or not.
