Hey guys, I jsut recently got my FD and did a few fuel mods to it. 1600/550cc injectors, Walbro 255 pump and a few other minor mods. After putting everything back together I tried to start the car. When doing so it cranks and sounds like it's trying to turn over but won't.



Now if I do that same process but give it the smallest bit of gas it will start up but only stay running for as long as I give it gas. When I say give it gas I mean I am giving it probably 10-15% of throttle. Does anyone know what could be wrong here?



A few questions as well. I just put in the Power FC to control the new injectors and pump but I haven't even gotten a chance to tuen it yet. I tightened the screw all the way in the TB and then loosened it a half turn like I have read. I also have been trying all this without my Greddy elbow on and without my IC pipes and IC hooked up. Does that make a difference?



I have replaced the spark plugs since the first time I tired all this because they were fouled really bad. It almost feels like the car isn't getting enough air. Anyone got any ideas?

That screw you adjusted is the idle control its probably the main problem so turn it out a bit further. I left mine alone when I put in my PFC.



I don`t think having the intercooler disconnected makes a difference but I`d try it with it back together your PFC does need to do its learning phase and everything should be connected for this.
