I'm have a problem with getting fuel to the motor, not matter what map I put in the ecu, I still run lean and bog down when I give it gas. So I need to start debugging my fuel system. Here are my ideas, please help me add some, if you have any idea what the problem is?


1. Switch to another set oof 450cc injectors
2. Test fuel pump(how do I do this?)
3. Test fuel pressure when driving
4

My setup is

d15b jdm vtec
450cc injectors + resistors
stock pump
td04 turbo
Open exhaust.... could it be because I dont have any back pressure?

 

What are you using to control fuel?

 

Wait, you dont have an upgraded pump with those injectors? Your pump cant support em.... get something bigger.

BTW, keep your exh. open you dont need back pressure when your boosted...

Blaze

 

get a fuel pressure guage

 

alright, sounds good

 

Replace the fuel pump and you should be good to go.

 

agreed, fuel pump with gauge. should be set..

good luck.

 

I replaced the fuel pump with 255hp walbro from lighting moter sports's deal for H-T
