Please help before I lose it! Crank sensor?

Sounds like a cranks sensor.

HOWEVER - mine had the EXACT same issue as yours and it was an ECU earth. I found this out after i'd replaced every other f**king thing, including the crank sensor.

New crank sensor done (£32 from unipart)!  Has it solved the problem?  Has it fook! 

Gonna go down the fuel pump & ECU relay route tomorrow.  Last chance before I test the car off a big fooking cliff!

Mate, seriously. Before you do that get an auto sparky to look over the car. Basically, like I said - mine was the same issue and was an ECU earth. I believe it was something like low resistance from the ECU to the crank sensor.

I left it at the garage so will ask him tomorrow.

Cheers!

No worries. Basically with mine, the reason it happend was because water had gotten under the battery tray and caused the wires to burn.

The state of the old sensor lead was a joke and would have needed replacing sometime soon anyway.

Is the ecu earth an easy check?

[patc]

Right. All done. New relays. New every bloody thing!
It does 'sound' better and start up instantly which it never did before. Time will tell!

Thanks for all the help on here!  I shall make a donation to the forum charity come pay day 

Finally found out what was wrong with mine  .It was the ignition switch  .So all's good,just need to get front speakers sorted for Harewood VW festival next week.

Ignition switch?!  Not another possibility!  How'd you find that out?

When me n me dad were mucking about with it (checking all sorts) he noticed that when the key was turned to No 2 position (dash lights) everthing was fine,but if the key was turned very slightly (not actually cranking the engine) the lights went out .So I pulled the multiplug off and poked some wires in (hotwired mis spent youth) and the car was fine .I bought a steering column off ebay and job done.
