probably not enough fuel. (stop driving it!!!)

what car, what engine, what's the rest of your setup?

it is only putting out 5psi so it really shouldnt need a different fuel pump or anything... 19 lbs injectors should be more than enough

fordguy17

you should get a bigger fuel pump. 24 lb injectors wouldn't hurt either.

Did you buy this kit new or used?
The new kit comes with a bigger fuel pump so what do you think??? We need to know what your combination is really.
Know matter what though, you should use at least 24# injectors even for a stock motor with and a minimum of a 155lph pump.
Type in what you have for the best possible advice.
