Aight guys I have a 90 crx with a b18a. The car has been driving fine till tonight...on the way back from the drag races it started hesitating really bad at highway speeds(60-70). I looked and I was throwing a code 43 ( fuel supply system). I pulled over to check everything out and it idled fine. When I went to take back off the car done fine. I was thinking maybe it was just some bad gas. But the code is still there haunting me. Has anyone else run across this problem, and if so what did you do to fix it.

I done all the searching I could and seems like nobody has ever answered this question.

 

BTW its a obd0
and brand new fuel filter.

 

Anybody???

 

i had this code about 3 years ago. everyone i talked to told me it was one of 2 things.
- oxygen sensor going bad
- vacuum lines came off

i checked everything out and all was fine, till i checked the wire harness by the fuel pump. i had a stripped wire grounding out causing my code 43. i replaced my whole harness and then the code went away.

Hmmm. Could be on to something here...I did to a wire tuck not to long ago. It might be one of the wires grounding out. I will have to go back and check...thanks!

 

no prob. when i found out my wire was grounding out and took out the original (DX) harness was completely F'ed up. so im glad i swapped it out for a full SI harness. good luck. let us know what you find out.

 

Will do! Going to be getting alittle surprise today that mayyyyyy help me out on my repair.

 

i had that code before and it was o2 sensor.
