Default RE: Re-starting an 850

Adrian, I had a wee knock in my first one, and the reason why I posted about starting it is because it has been in garage for a couple of months since. They offered me a courtesy car - a corsa!?!?

Mmmm... let me think. Nah, straight to the bank, get some cash and go get another one while I wait. I think my car is ready now, but I am kinda enjoying this one now (and I can't be bothered). It is much faster (obviously being manual 2.5).

Have you ever driven a 2.0 auto? I think that is what caused the knock - I must have fallen asleep. Slow? It's embarassing! I think a T5 will be coming up.

Dave is quite right about spinning her over to get some oil pressure prior to starting - a very good idea. On "old" cars the way to do this was to pull off the HT lead ... However, on these new fangled things it's better to disconnect the flywheel sensor lead and then crank it over. This fools the ECU into thinking the engine's not actually spinning and hence no fuel or sparks are produced but oil pressure is built up. I always do this after an oil change to make sure the oil is where it's supposed to be prior to firing up ...
Good luck

Not if you only give the engine a couple of turns. The amount of unburnt fuel getting through to the cat will be minimal if any as the car has been stood for a few months and would not do any damage. It is better that you get the oil to the top of the engine, having hydralic lifters more damage would or could be done by the engine turning with no compression and lack of oil.

Hi Tom,

The sensor is located on top of the clutch housing next to the block - it usually has a circa 6" fly lead ending in a 3 (?) way connector block clipped to a nearby hose.
Disconnect it at the connector block and crank the engine until the oil light goes out - the engine is now primed and ready to go ! Re-connect, fire her up and enjoy ....

All the best

Dr D
