Hey guys im new here but have a problem that i cant quite understand. I have a 2002 audi a4 quattro 1.8t and last night i went to start the car and it wouldnt start. I pushed it home and hooked up my scanner and i got a p0321 code. I went out today and bought a crankshaft sensor and installed it and still no luck. If i leave the car for a bit it will start for maybe a brief few seconds and then shut off. I really need to drive my car adn i have no idea as to whats wrong can some one please help me as soon as possible. Thank you very much in advance.

thats the part he said he already replaced. make sure its plugged in well and that the bolt is tight

 

So if after the sensor was install is still giving the same code, then probably a bad connection or bad new sensor.

 

after i installed the new sensor i cleared the codes and nothing came back but it still wont start any ideas?

 

coilpacks?

 

make sure you have fuel pressure. There is a bleeder valve at the firewall end of the fuel rail. i used a torx bit to make sure i pushed it in all the way when i checked mine last. turn the key to on and then push that in. quite a bit of fuel should come out.

its a schrader valve like a tire has.

 

^^^ so it acts like is flooded?

 

Well guys i went out and checked for power at the pump. Just to verify it is the 4 pin connector right? I pulled out and checked this connector for power and i got 1.6v , 0.25v, 0.03v and 0.00v this is with the key on. Im guessing that there is a wiring problem to the pump now?

 

So there's no pressure at the rail??
