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

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

i have been advised to just cut the plug to pieces until i can get to the connectors and just plug them in, until the new one arrives

No paperclip test will work ok on a 2.5 V6 lump

it will  :-? :-? :-?

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

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

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!

the multiram actuators move

ok so actuators moving= working

do they ever fail intermitantly? as i notice some times i drive that car it feels flat, while other times it pulles like i am being taken by the gravitational pull of the moon

Remember the fuel maps assume that the multiram is there and working.

When the multiram doesn't work, as on TheDaddy's car, its flat as hell

ok i think i may have been wrong about my multiram working fine.

every now and again when i plant my foot i feel a nice serge...but over the last few days it seems to have gone flat....i was driving on a round a bout the other day and put my foot down and it pulled like a train.

i done the same today and there was nothing there to get excited about, and i let my mate drive it, he is used to a 1.4 pug 306 and he did not seem to impressed either

is there a way to test if the multiram is working as it should?

it might just be how i am driving it  :-?

Blip the throttle wide open from under the bonnet and you should see it work

what should i be looking for?

so the multi ram is there to spread the torque rather than have it peek?

are there any graphs to show what the torque curve is like without the multi ram? is it there to smooth the ride of the engine...the link is a bit bleek, and still doesnt really explain a aweful lot
