running problem (fuel starvation)
Turbo Mini Forums

i know this has been posted befour, i have searched for this but nothink fits my situation
how do i start
first off i am using a n,a engine (fully rebuilt) turbo one has gone off to have its mark put on it.
it has a kent cam 726 i think, vernia pullys, new uprated oil pump everthink else is as standard 1275.
i have fitted a turbo off metro, accuater, and plenum also i have fitted a bosh fuel pump with a proper regulater, the fuel line is airo quip 8mm internal diameter with a 8mm return line, this does not go into the tank but into a tee piece. i have 8mm pipe to tee piece then 10mm exit from tee to pump them 8mm from pump to carb. what is happening is when i rev it it reves up then dies down to about tick over then revs up again and so on (axcellarater flat down all the time when trying this) the only thing i can think of trying next is the dizzy off a metro turbo (told it is different) i know timing is right as engin was running fine befour fitting turbo and have not toutched anythink else, has anyone of u briliant minded people have any ideas, thank u in advance

Advice?

Try spelling "thing" with a "g" at the end, and that button on your keyboard above the "Ctrl" key lets you type CAPITAL LETTERS.

After that, have you checked the fuel pressure whilst it is doing this revving up and down thing.

WHAT PRESSURE SHOULD I BE LOOKING FOR

3.5 psi when idling I believe, the fuel pressure should remain this value above the boost pressure as boost pressure increases e,g 10 psi boost 13.5 psi fuel. Someone please correctme if im wrong!
