Urgent - Engine won't start
« on: 05 May 2009, 11:22:06 »
Changing the rad on sunday, all went well, drove the car Sunday and Monday, went to the car this morning, engine will turn over but will not fire, found the connector on the 'engine fan' hanging off so reconnected, checked all other connector things look ok.
Still will not fire, engine management light on and stays while engine turning over.
An help please !!

It's started !!!!!!!!!!!
Took out paper clip, turned key, started first time !
Could it of been something to do with the time between replaceing the fan connector and turning the key ie some type of time delay ?
Very strange.
Thanks for your help.

I thought you always got code 31 one if you paperclipped without the engine running

31 with engine off will always come up...no engine running so no crank running so no signal from crank!!

Do the paperclip test again with engine running...

P.S does sound like crank but 31 with engine off is normal for all so proves nothing

right. Apologies to all. I was not clear.

I was translating 31, nothing more.

That aside for a moment. Def sounds like crank sensor to me even if 19 not present imho. But i may well be a bit premature, esp if fuel level low.

To clarify to Richard 31 does not mean crank sensor failure as all have said. Constant cranking and not firing is common with crank sensor failure. To then start i while later is also common warning of cs failure. 19 not present not unusual at this stage, as with my omega. If it happens again within a week or so suspect cs, verifie with paper clip test code 19.

 Sorry mate, made a pigs ear of your thread.
Hope clear to all? Whoops.

Hi mate
Does your car go over 3500rpm?
I had code 19 and the car would not go over 3500rpm it just spluttered. Got new cs and now no probs. just got to get MOT (Failed on Broken Rear Coil spring and Steering Idler arm :'()
Hope you get it runing the way it should soon :y                                                                                                                                 Dave.
