ok so i have a 88 integra, obd-0 of course. About a week ago the fuel pump went out on it and it boggs out every time i give it gas. i know it is getting fuel to the head. checked injectors, some o rings were shot so i replaced them. still bogging. I put a b&m fpr on thinking the other one was shot (plus it looked a little rusty). changed the fuel filter with a brand new one. changed cap and rotor along with plugs and wires still doing the same damn thing. i honestly have no clue y it is doing this. no check engine light and no code on ecu. I did take it to many garages around my area all mechanics were clueless. a couple of them said maybe a clog in the exhaust. so i took off the exhaust still the same. also took out the o2 sensor. i also tried running it open throttle body, maybe not getting enough air. when i check the plugs they are a little black and not white at all so its getting fuel. Any help or input would help alot. i need HELP!!!

 

ok so no one knows about honda engines?

 

yeo wats good yea i had the same problem wit my car its the knock senor iight if anythin else hit me up 1
lopEz VTEC ALL DAY

 

hey i didnt even think about trying that thanks dude ill try it tom and let u know

 

idk, does the car overheat? if so, i'd say catalytic converter's plugged.

 

yeah one of my friends thought that and so did a mechanic i took it too, but i took the exhaust off from the header, and no it doesnt over heat. i'll check the cat out tommorrow and see also try the knock sensor i believe i got a couple laying around

**added** it also ides perfect after it is warmed up, right when u start it and has been sitting it runs good till its up to temp, maybe a clog in the header?

 

ok so i checked the cat out and it doesnt seem to be clogged so i beat all the **** out of it so now it is hollow. still running the same. also after thinking about it obd0 doesnt have a knock sensor.

 

What do you have the fuel pressure set at? I had a similar problem and turned out the FPR was set to high, the other thing that contributed to my problem doesn't matter on your car (referring to O2 in the cat).
