Hey there. Hoping to get some guidance here.

2000 Audi a4 quattro 1.8T -

Seems like a security issue possibly. Car Wont Start but will crank. No spark and No fuel pressure. Replaced Crankshaft Sensor as I read many issues lining up with mine. Car Started once, but then wouldn't start again. Took that sensor out, and put the old one back in. Unhooked the battery for 10 min. Car Started once but wouldn't start again. I have done this 3 times with the same results. It starts and runs fine but as soon as you shut it off, not fuel pressure or spark. And obviously won't start. (No warning or check engine lights on the dash)


Help Please. Not sure what to do next
