Hello fellas, Ive had my 2003 audi a4 1.8t Q for about 7 months and this is my first mechanical problem in which i desperately need help with. so here it goes....

Driving home at about midnight on a Friday on Very low fuel.While i was coasting in neutral my car abruptly turned off. /my whole cluster went out and so did power steering, so i pulled off the road.i tried to crank it but it did not turn on.I assumed my car turned off due to the low fuel, so i walked to the gas station and came back with a gallon.After i dumped the gallon in i tried to turn on my car ...cranked it a few times but it just wouldnt start.i wasnt sure what it could be so i started googling similar symptoms.....So i finally tried to "prime" my fuel pump my turning the ignition on and off in intervals of 10/15 secons for about 15-20 min and it worked!my car turned on and i got home that night.

The following day on a saturday at 11 am i got in my car and it turned of normal.i drove it for an hour or so and it ran fine.about 8-9 hours later at 9pm i attempted to turn my car on again, and this time it just wouldnt start again even after trying to "prime" my fuel pump again.

since then i replaced fuel pump,fuel filter,and fuel relay , none which have gotten my car to start again. My fuel pump still is not getting power, nor is there any fuel pressure.I took a spark plug cable out and checked for spark....no spark either.I am now assuming the problem is the crank sensor(CKS) based on other threads i have read.I appreciate any input or ideas.And if you're from the Los Angeles county with have a vag-com available to lend a hand so i can pin point what is the problem.....thanks in advance.

 

I'd replace the ignition switch first - it's cheaper, easier, and often causes start/run issues on these cars.
