Still didn't get a chance to hook it up to diag. Been busy at work,finishing late every evening didnt have time to do anithyng and that f**kin rain just keeps on falling  I was thinking could it be immobiliser cutting fuel off and not the crank sensor??? Because as soon as it has fuel engine starts no prob and the rev counter works normal and i know rev counter picks it up from crank sensor(i confirmed that by plugin it out).could it be immobiliser???

Has it got or had in the past an aftermarket alarm/immobilisor? These are usually spliced into the fuel pump wiring and if it's been badly removed in the past it could be causing a problem.

Yes it does actualy but it seems to be deactivated

[Simeon]

Worth tracing the wiring then.

Guys today i hooked it up to a code  reader and there was no faults at all, so i thought thats f**kin weird ....said maybe the battery was disconected so i might crank the engine again and something will come up! Cranked the engine and boom it started straight away no problems!!!  went for a drive warmed it up and thore the asshole out off it all good!!! As much as i am happy now i am also pissed off because i dont know the bottom of it... I think i will remove all the wiring from that stupid aftermarket alarm because now i honestly have doubts that something is wrong with that!  Guys thanks for all the help and i will post some pics so you know it was worth fighting for  once again thanks!

Hope the problems fixed m8.One word of caution tho,a faulty Crank Sensor will not always show up on VAGCOM.
 
Good Luck
