Hi ya guys,

A friend of mine has recently rebuilt a series 2 rs to standard spec. He's got the lump back in and connected everything up however is having some problems with the electric fuel pressure regulator that sits on the side of the metering head. When the electrical device is disconnected the car seems to run / idle fine, however when he connects the electric fuel pressure regulator it runs lumpy as hell and dies on idle.

Suggestions ?

Thx, Swanny

 

Something is probably telling the fuel ecu to richen like hell. Perhaps something wrong with the water temp sensor or it's wiring?

 

I agree with Jesse - check all the plugs are on the sensors. IM guessing one isnt on properly, or u have two or more mixed up.

 

Thanks guys,

I'll pass this info on to me mate.

 

Usually water temp sensor or the wiring when this happens. Without that pressure actuator, he will have no on boost enrichment..

 

bro is this kendals motor?

I have all of my plugs disconeted prity much and mine runs fine, so did my metering head he is runing plus ive used his fuel ecu in my car and he has a new fuel pump so the prolem sould be narrowd down to a few things now.

Maybe some of his loom is fuckd that goes to fuel ecu?

I cant belive his motor still isnt running pmsl

 

Yeh its kendals motor bro, Spoke to him last night he seemed to think it was running better today - maybe where its been off the road for so bloody long just needed the cobwebs blown through... one day he'll get it on the road
