I have a starting problem with my rst which I think is electrical.
When car is cold it takes a good 10 turns before the car starts up. When car is hot and left for half hour or so car will start after about 5 turns but u have to catch it with the throttle. If u dont catch it sometimes the car will not start at all. You have to leave it for about 15 mins and it normaly starts then or bumping it will start it.
When running the car drives great. Never cuts out and runs perfect.
I have had all the fueling checked by a garage cold start, pressure etc etc and everything is fine I was told it must be electrical.
I have changed spark plugs
Starter mota / battery (engine spins very fast now when trying to start)
Have tried swopping the fuel ecu to a spare 1 I have.
Have tried unplugging the cold start valve.
Any ideas>??

Thanks

 

timing out ?, water in tank? wiring loom problem? just throwing a few ideas out ! imboilser?

 

Have you got the heatshield on the starter motor, the turbo kills them very quickly if you havn't and the work intermitently and then they die

 

Had similar probs myself...and now feeling hugely chuffed that it's running better than ever!

How? Quite easy and very cheaply. 1 can of electrical contact cleaner, 1 can of carb cleaner, 1 tub of vaseline and half a dozen hours.

Disconnect battery, then disconnect every electrical connection (1 at a time) ie supplementary air valve , cold startvalve, engine sensors...every connector you can see. Spray terminals and plugs with the contact cleaner and "work" the connection (some of mine had a lot of corrosion on them) Smear some vaseline on the connector...this will keep them corrosion free.
Also cleaned up terminals on battery, body earths, starter connections.

Next remove the throttle body and unscew (count the number of turns to remove) the idle speed screw. Spray carb cleaner up the idle speed screw passage - mine was full of gunge. Clean the throttle butterfly and body. Re-instal the throttle body and idle speed screw...screw in the same number of turns as it took to remove, to give rough idle speed setting.

Supplementary air valve (bolted under inlet manifold) Remove and clean out with carb cleaner followed by WD40 - re-instal.

Connect battery and start, warm up and set idle speed....absolutely wonderful. Smooth and steady idle speed, clean pick up and catches straight away from cold :top

All very simple and basic. Also make sure all breather pipes are clear and not cracked...and make sure the oil dipstick is firmly located in the tube!

Hope this is of help
