Couldn't you take the crank sensor out of your good car and try it in this one ... ?

Was thinking that Dan but it's in an area of a place to get I to and don't want to risk two dead cars.

My bad - thought the sensor you were on about was the one on the front of the engine block. My Mk1 had a starting problem and when I got one of them for £10 second hand it was sorted. Maybe that sensor then mate - I thought it was the crank or maybe camshaft sensor ... ?

It's certainly easy enough to swap out - even I did it!

The one at the front is the cam one Dan the crank one is around the belts I think.I have a spare cam sensor sitting as well.sods law really.

Don't forget when changing the loom you may have disturbed the sensors that were running ok but were on the edge.

Get the battery fully charged before trying to start the car again.

Simular problem with mine . Turned out to be the fuel regulator valve was open therefore no pressure in the fuel system . When turning the ignition does the pump have a high pitched or deep ? Another test would be to remove a spaek plug and crank the engine , I believe if the crank sensors faulty then you wouldn't have a spark. ( don't hold the spark plug , hold it on something metal )

may sound obvious, but have you double checked engine bay fuses?

So went out for a look today.fresh battery,fuses,fuel kill switch,fuel pump, priming normally.still won't start.code reader then shows multiple codeshttp://i168.photobucket.com/albums/u...6-13-58-44.png

Couple more questions guys.is the crank sensor in a different location on the mk2 than the mk1 as I can't for the life of me find the bloody thing using the sensor location diagram which is on the site and also now it is blowing a fuse in the engine fuse box when the battery is connected any ideas as to why that has just started.getting fed up now.this car may end up getting broken if I can't get it running soon.

The crank sensor will prevent it starting, the other 2 won't.
It is located down the back of the engine, just above where the drivers side shaft comes out of the gearbox.

I'm not sure about why the fuse keeps blowing
