i parked the car up at night, went to drive to work in the morning and the car is just turning over and over

at first i thought i could smell fuel while cranking the engine...but i loosened a spark plug (finger tight) and cranked the engine for a good 15-20 seconds and quickly whipped out the plug and it was dry as a bone

also i have no spark.

so what do you think?

crankshaft sensor or ecu? or maybe something else?

normally crankshaft sensors are a fairly hardy and simple bit of kit which never really tends to go wrong

also i unscrewed the sensor, and i cant find where the hell it plugs into, the wire is covered in heat proofing and ran up behind the blooming oil cooler pipes so i cant even wiggle the wire so someone else can grab it!

Classic crank sensor failure mate - do the pedal trick - bet you have a code 19.

Plug is up behind the plenum to the right of centre when standing at the front - whip the plenum off makes it easier to locate

Not on Omegas! Well, that's nto strictly true.  The sensors are great, but the cables aren't high-temperature enough for the way Vx routed them.

Yep reroute it to the right and down past the abs block

so its almost certainly the crank sensor then?

i have a spare 2.5 vectra one at hand, can i just cut the plug off and use this one for now?

blooming car, i have to drive my sister to her wedding next thursday i could really do without the hassle from the car atm, and i am moving, and its my sons birthday, and the car just decides to go nuts on me

Do the paperclip test 

If 19  comes up, its the crank sensor

Wouldn't recommend that mate - probably wont work

i was under the impression that the paperclip test would not work on the omega past 2000 plate?

If the plug is the same, it will work. for a while, becouse it does not have the heat protection. But for a emergency, that will work ok. Got mine from Saab dealer who had it in stock

No paperclip test will work ok on a 2.5 V6 lump

[mr carl]

the plug is square on the vectra one, and the plug is round on the omega one is it not? i have not had the pleasure of finding mine yet but the plug for my other sensors are oval

could have worded that better my man, you mean it wont work on a v6 lump, or no, the paper clip test will work?

sweet, but on my calibra if the engine was not running then the paper clip test would throw up the crank sensor even if the sensor was fine

The plug went from square to oval in either 96 1/2 or in the 98model year... correct mi if I'm wrong
