Title: Help!!!!!!!!! Please
Post by: rob69 on 19 February 2011, 19:44:26
I drove my car home from work last (2000 2.5 elite 80k auto ) as usual she drove perfect no problems nothing suspicious happened.
But this morning i went to go to work and got in car and turned her over and she just spins and doesnt fire at all.
 i have checked the obvious i.e: fuel and the batterey has plenty of punch but it just wont fire ?????????
p.s i also checked that the chip thingy is still in the key fob so im lost any help please ?????????????? i need to get it running asap for work.
A friend has suggested it might be the crank sensor and has offered to come over in the mornin and remove his sensor  and fit it to mine to see if thats the problem anymore help guys from your knowledgable heads please. :-/

Do the paperclip trick and post up any codes .. if you get a 19 it is almost certainly the crank sensor.

I've just had to remove mine to give it a good clean, (wrong oil filter fitted, which then exploded sending oil everywhere).

It's really easy to get to and to undo the E8 bolt, (I think an 8mm or 6mm should also fit?), but do be carefull getting it out. If it feels stuck, which it likely will do, gently give it a prise with a flat bladed screwdriver and try gently giving it a little wiggle. Eventually after a good 5-10 minutes it will come out.

I cant stress enough that you need to be gentle with it.


I cant comment on the wiring side of it, as all I did with mine was remove it to clean all the oil off it.

Code 31, no RPM so either
- the engine isn't turning
or
- the crank sensor is FUBAR and can't sense the engine is turning

No crank sensor = no spark

When my crank sensor failed (on a 1994 2.5 V6) I didn't get a code 19.

Not really, I'd take your friend up on his kind offer and see what happens...

As its the crank sensor wiring that breaks down you could try finding the wire where it runs down the back of the left hand bank and giving it a jiggle.

Got me home from Greece last year.

Classic crank sensor symptoms. No guarantees unfortunately but I will be extremely surprised if it isn't your crank sensor.

Wow! A friend prepared to immobilise his own car to help you :y

The crank sensor wiring runs too close to the exhaust manifold and gets brittle and fails. It is installed at the factory tucked in with the oil cooler pipes. If your friend manages to extract his from behind the oil cooler pipes there is a chance it won't work after it has been disturbed  :(

Ok guys  well we abandoned the idea of immobilising one car to try and fix another lol but what a mate :) hey.
Anyway towed it round the corner to his house jacked it up in the air got under it took bolt out of sensor gave a it a quick wiggle and a kiss put bolt back and out of interest turned it over on the key and brooooooooooooooooom off it whent first turn so im guessing thats conclusive its the crank sensor unless moving the car a mile or 2 fixed something else lol but gonna order and fit new sensor and seee what happens :y
Thanks again everyone for your speedy concise answers will update if it turns out to be soemthing different .

Hi Rob, everything still points to crank sensor. They often work after being refitted and this will get you out of trouble but don't assume that it is fixed. Get a genuine GM replacement and at least carry it with you as it is likely to fail again (at the most inconvenient time of course  >:( )

When mine failed the AA towed me 10 miles home on a rigid bar. He got me as close as he could to where I wanted it parked and then I intended to use the starter (manual gearbox) to move it the last 10 feet. It started first turn of the key  ::) so I parked it but it wouldn't start again 30 seconds later.........
