Well I'm pretty sure the cut off is fine. I honestly dont know whats going on, except maybe my fuel pump is too strong? Because I cant lean it out. And my smc is 99.999999% right.

Do you have an adjustable fuel pressure regulator? maybe your could turn the fuel pressure down with that.

BlinD

stock fpr. What I dont get is that I've seen people with the walbro 255 pump working ok. Crazy ish.

tranceminister

Yeah, I don't get it either. The walbro pump is good for turbo setups. I'm confused. OBD2 sucks, so that would explain the check engine light. It senses too much fuel.

prime the turbo? i'm sure it would be fine if you just started the car and let it idle... its not like you're spinning the turbine to hell

the pump you are talking about is a second pump right?? you cant run wo a fuel pump. sounds like that pump is fucked up. try the bigger injectors and afc without the pump. if that works then mess with the pump. the bigger fuel pump shouldnt change the static fuel press, it should just be capable of a higher flow and pressue. thats how it should be set up. get a fuel pressure gauge and see what fuel press you are running w/and wo the 255 pump. (you can always return it at autozone)

Well I dont know what to tell you, but the power line is cut, and switched, and off. And the pump is not working heh. Also I gassed it a little, and its very slow when coming down off rpms.. What all could this be symptoms of?

mine didn't wash while i pulled the wires to prime, but when i cranked it to just pull it on the flatbed and then to get it off the flatbed and then to move it from the parking lot to the bay at the muffler shop without letting it warm up. rich settings and then the ecu running in cold mode (rich as well)=whole lotta fuel in left in the cylinders for it wash away the cylinders. and i'm sure of it because it wouldn't start when i went to pick it up and i did exactly what i told him to do and it fixed it. i also changed my oil because it had gas in it as well.

set your corrections so that your idle rpm 1k or 500rpm (if it has settings that low) is the equivalent of a 240cc inj. on safc it is -47 or -46.

BlinD

Already have, didnt crank until the pump was turned off.

did you scan your code to see what it came on for? reset your timing to stock and use your stock pump. remove the fuel cutoff switch and reconnect as stock. this sounds way wierd. the only other thing i can think of is the resistors or smc is wired wrong. did you cross reference the wire colors you spliced into at the ecu using a shop manual?
