Forums Forums Enthusiast Forums A - Z Autowirral Running problems on RST again.

Won't be injectors matey as the problem would be constant.Could be the plugs,but it won't be the gapping of them,as,again,the problem would be constant...but they could just be knackered.

Fueling is possible,but unlikely; unless it's the metering head-butterfly, catching on its housing(easy to check)...Did this start when you changed the fuel pump???(s2 is efi NOT mechanical inj )

As Stuy said ,its probably electrical...pop round if you get stuck mate

The pump came on the car. I never fitted it but ive got a receipt saying its about 6 months old. Its mounted in the bay instead of near the tank.

Ive had problems with the immobiliser. Sometimes it wouldnt start up, itd just turn over but no dash lights would come on and the pump wouldnt prime. That was intermittent until i had a nose then it was ok. Then all of a sudden sometimes itd cut out if i flashed my main beam or turned too many electrical things on. It wasnt a fuse and itd go away if i fiddled with the immobiliser wires. Then i messed about and moved the wires and since then it hasnt happened for about 2 months. The immobilised isnt cutting the engine as the warning lights dont come on (theyre disconnected so they flash for 30 seconds or so) but would the immobiliser be connected to the fuel pump and could it possibly cut fuel for a second?

Soon im getting a new alarm/immobiliser but i could get it done sooner rather then later if anyone thinks it could be an issue?

Bin the immobiliser soon as you can! Sounds like you have some major electrical gremlins in there mate.Also are those pumps gravity fed?? If so,is it mounted below the tank height??

Stan is your man...Wirral auto electricians in Moreton.I have used his services on any jobs that I couldn't do myself-he is very cheap and a guru with electrics

Its mounted way above the tank. I dont know anything about them, never even knew they existed until i bought the car but apparently every RS turbo or cossie uses them

Where about is he? And do you reckon he'll be open tommorow and does anyone know where to get a good alarm immobiliser, Preferably a tatcham approved, but you guessed it, doesnt cost the earth?

You can check if they work properly yourself. Just get an inline fuel pressure gauge from demon tweeks, depending on your injectors, they should have a constant 3 bar fuel pressure (check what the pressure is with an RSTurbo expert to be sure ).

First thing which came to mind, get yourself on passionford.com ask on their as their are plenty of S1 owners which have had problems like this.

did you get this sorted mate?

Nah i havnt sorted it yet. The car runs fine normally, and when its playing up it still runs ok without more then a quarter throttle so ive been using it sparingly.

Im right this moment looking at Rolling road centres that do diagnostics and are familiar with RS Turbos / Turbo cars though.

My short term plan atm is get it running properly, get a dyno run in, FMIC, Immobiliser + alarm, quad light conversion, maybe wheels, another dyno/remap session and ill be happy then.

how about jamsport?

I has a xr2i and had similar issues but it only repeated this once or twice it was if it was only firing on 3 cylinder, it was due to a hydraulic tappet I think

i have come across this my self if you take the hydraulic tappet out and just check for cracks in the side of them

i have done inlet 1,s on number 3 too

Ive had a look at jamsport, and the tuning package they offer there is very tempting btw, but its too far. I dont really fancy driving far on an engine i know isnt quite 100%

A few people have suggested cam / lifters. I presume its a head off job to check them? I havnt had the rocker cover off yet so i dont know what they look like under there.

The alarm is sorted now btw. The one on it is already cat 1 approved and i found the certificate. Im still getting the wiring checked though.

I dont think you do have to take the head off just the rocker cover, let us know how ya get on.

OK, had the lifters out today. 6 of them where spot on but one was pitted around the bottom edge and was slightly sticky getting it out. The other was the same just nowhere near as bad. However i dont reckon this is the problem. Im going to have a look at the price of newens and change them as a matter of course, might aswell.

Had a look down the holes and the cam looked fine, a little wear but nothing to worry about.

Any suggestions anyone?
