my rs turbo fcuked up lol, i was red lining it was flying, after the race wen i was drivin normal, started 2 hesitate n struggle 2 move, i jus had it dyno'd 2 weeks before at 233bhp@16psi (flywheel fig) so i thought pistons, took engine out there fine, but i swapped the head wiv a fiesta turbo 1 an used a adaptor plate from oddkidd so i got frst head on mfi management, put it all bk 2geva an it wont start, ive got petrol entering the metering unit and the return, but no petrol coming out the 4 union red injector pipes,any ideas plz help i want to get my rst bk on the road!!

ive changed/checked the following
black ecu
plugs
meterin unit x2
earths/sensors/clips/pipes
pink relay

i havnt changed the relay in fuse box thts got ke on it, is tht worth changing?

it starts like it runs on 3 cylinders for 1 secound then cuts out, im guessin thts the cold start fuel feed, as its not metered, plz help!!!!!!!!!!!!!!!!!

 

did you take the pistons out to check them or just look @ the tops

mine where fooked down the sides looked mint from the top

 

omg thts horrible........no i jus checked the tops there wer no scores on the inside of the pots tho, i think my problem is something electrical as it wont send petrol out the meterin unit into the 4 red pipes, im really stuck

 

did u do a compression test before removing the head? as above u could of damaged the side of the piston and u wont have seen it from the top, ive done that before

 

Try pressing down the flap in the metering head whilst cranking, only 10mm or so. Do this and it should start.

i understand what u mean by the pistons, i didnt do a compression test, im just trying to get juice up to my injectors 1st, then take it from there,


iv tried holdin the flap down also, no good, theres jus no pressure cumin out the 4 pipes out the metering unit grrrrrrrrrr

 

That is weird. Is there fuel coming through the pipe from the pump? If there is it's definately a metering unit fault, which is normally caused by the flap......

Deffo not a compression problem.

 

if running on 3 the first thing u should do is check compression just to rule it out, esp after giving it alot of stick

if there is no fuel coming out of the fuel metering unit unscrew the top of the metering unit and check to see if the plunger has got stuck, this is what the flap pushes against to release fuel, or another way is to tap the top of the metering unit with a hammer whilst someone cranks the car over and if the plunger is stuck it may release and the car will fire up

 

'''''That is weird. Is there fuel coming through the pipe from the pump? '''''

yes m8, there is fuel cuming out the filter pipe with plenty of pressure, but theres no pressure inside the metring unit, iv tried tappin the flap 5-10mill whilst turning it ova, i even tried pushin down on it a couple of inch an it makes this buzzin sound tht sounds electrical from sumwer behind the inlet manifold area ???

 

got to be meterin unit!

 

iv changed the metering unit, still no luck, do u think its a sensor not sending a signal or sumthin like tht?

 

are the 1's on the back of the inlet deffo plugged in!

 

yh i had blue an yellow mixed up at 1st wen i checked them last week, soon as i swapped em round, the cold start unmeterd fuel was startin it for 1-3 secs runnin on 3 cylinders then cutting out cuz its only the cold start supply gettin 2 the engine

 

im outta idea's now

 

Heres what you can do.... fuck the metering unit off and go cossie management and efi SIMPLE!!!!!

 

check the fuel pressure regulator that sits at the back of the metering unit. Last time my RST died it was due to that as it totally blocked. The cold start injector is not governed by that and that could be why it runs for a few seconds as its running on the cold start.

 

had the same problem with mine,spent months trying to figure it out,binned the mfi in the end and went efi instead.Better all round

 

iv changed the pressure regulator, i think, is it attached 2 the back of the meterin unit to the left?
i hav all the efi bits needed 2 convert it from mfi, but im unsure on the loom, how long would it take to convert, wud i b able to do it ova 2 full days nex weekend? cheers

 

providing you know what your doin it should take you a day or so.providing you dont hit any problems.

 

ok cheers any more ideas b4 i go to efi tht might b my problem ?
