as above just had full engine rebuild cvh rs turbo on std injection went to start car and just turns over and wont start cracked off all 4 injector pipes no fuel coming out of them i bridged fuel relay to run constant and pushed down on metering unit flap and it then sprays petrol out of injectors but it just dont do it when u try start car..ive now changed metering unit to 1 i deff no works an still the same so its not metering unit what else can it be is it an air lock ???? as car was sitting with empty tank for ages and fuel pump was primed with no fuel in tank when i re fitted loom so might be this but have tried to bleed it but not sure if done right..

any other ideas as i thought i had sorted this but looks like i aint

cheers

Could be an air lock. How did you go about bleeding the system?
Also is the pressure correct? I had a VERY similar problem but it was all down to fuel pressure. there just wasnt enough of it. Also have to checked basic things like the fuel filter?
Couple of ideas anyway

i just cracked off all 4 injectors bridged fuel pump and pressed down on metering head flap loads an i mean loads petrol came out so much that it flooded engine an i had to change oil i have put a new fuel filter on its got an arrow for fuel flow on it which point towards headlight so hope that s the right way...if it is pressure might be pump then ?????

cheers

im not 100% sure but the metering unit is a pretty delicate piece of equipment so surely pushing down on it loads will fook it
It could be the fuel pump not producing enough pressure. Isnt there a regulator on rs turbos? When i had a problem it was actually one of the lines(the one going from the metering unit to the fuel filter. It wasnt holding the pressure properly. so replaced it and all was well. if you can try and plug in a pressure gauge at different points and see whats happening where

turbo.jon

they do have regulator on turbo s will have to get a new pump see if that sort it if not replace the whole lot

turbo.jon

just tried diff fuel pump still no good... there is loads of pressure and fuel in coldstart valve just none from injectors

turbo.jon

well got it to start a min ago but it just dies a couple seconds later still no fuel from injectors so just cold start making it run.....

tried the fuel ecu?, or the heated seats fuse, that is the fuse for it, did u put it in when u changed the loom?

This is likely a very simple airleak or the cam timing is wrong/different which means you will have to adjust the metering units base position.

turbo.jon

tried fuel ecu so not that also its got fuse in

turbo.jon

will have to have a look for an air leak bit hard to find though

how do u adjust metering units base position???? as this sound like what it can be as i no of 2 others who have just had engine rebuild s and have same problem .....

Common one is the pipe from turbo to metering unit has been put on wrong, thats deffo my no1 airleak for a total non runner.

Dump valves? take it off totally till shes a runner.

Golden rule.
If the engine can draw air from ANYWHERE other than the metering flap, it will not suck the flap down and thuis the head will not inject fuel. This includes cam covers and dipsticks, so search carefully.

Fuel adjustment is done of the 3mm allen key adjustment next to teh flap but anymore than 1/4 turn will NEVER be necessary. Adjust with EXTREME caution or you may never hear her run again, i kid you not.. lol

turbo.jon

you got it mate cheers just tried dump valve an its sorted started first time at last it works just need few little jobs doing now and i should be able to drive it

thanks again
