Fuel pump not engaging on turnkey Help!
 

When I turn key on my fuel pump will not engage/'prime'. The car starts but of course there's no fuel pressure so it is really rough.
I have the Bosch 005 pump (from 034 motorsport). After the car starts it runs fine, just wont prime on turnkey.
Any ideas on where to start????

Kinda strange who installed the pump?? did you follow the instructions??isn't there a line that needs to be capped off on the bosch pump or maybe thats on the rs4 pump i am thinking off.If you have no fuel pressure when you start the car make sure your fuel filter is installed in the correct way maybe you replaced it when you changed the pump???and installed bakcwards???arrow on the fuel filter should be pointing towards the front of the car.

Hope this helps.
