I can't find it an where, I'm popping code 43

[phat87mazdarx7]

My 90 Crx HF has a b18a1(ls) and its pulling a code 43 when I looked it up it just pops ups
43 92-95 Civic
90-95 Prelude
94+ Integra Fuel Supply System defective or malfunctioning fuel supply systembut else but not crx. the guy I got it from screwed up some of the wiring(he thought the hf was a dual point car so they tried to do the wiring conversion) I undid most of his wrong that I know of(mainly the tps, had the code up but when out after i swapped the wires around). what do you guys think I should check. I know its going to need a new harness but I'm not ready for that yet, lol(don't want to pull the dash). I bought a new Fuel filter(one on the car looks kinda old, then the o2 the plug(terminal inside the plug,) was not in right so I fixed it(pushed it further in till it clicked, that code was popped but this got rid of it) an I put electrical/dielectric grease on ever single plug and connectors.

I kinda think I may have bumped something working on my radiator(92-00 half radiator, all aluminum)I drove it around a bit after I fixed it(got it out of limp mode) and it did not night up at all, but now it is on as soon as I crank it up, how do I clear it out, after I try some of your suggestions to solve this issue

I really need help here, the car runs great but tat damn light is scary


PS. My speedo is acting funny too, it bounces around about 1-1.5 inches up and down till I hit about 40, then it settles don't to about 1/8 inch(maybe less) bounce

Either its not wired up right so its readiding nothing so its throwing the code, or its faulty.
If all is well have somone flash the ecu to make it go away.

when you flash the ecu, does that disable the engine light from ever comming on agian ?

Code 43 is fuel supply.

blanco, i'm usually on your side.. but read man.. he knows what code 43 is.. just wondering how to fix it.. i had the same problem.. i changed out my fuel pump, fuel filter and fpr.. it hasnt thrown the code in a long ass time but occasionally i'll get it again, but the car isnt shutting off like it was.. if it starts again i'm changing the injectors and hopefully that solve the problem

this was already solved and I emailed someone to delete it, I posted it 3 times by mistake, thanks

PS It was the tps sensor plug if you wanted to know, I guess I pulled it out when I tried to spray the speedo cable with wd40.
