If you pop the lid off the main pump relay and press the contacts in with your finger, does the pump run?

Aug 2011 at 12:03 As said, pop the lid off the right hand side one and press the contacts together whilst the ignition is on. Get somebody to check the fuel pump runs whilst doing this and also check for the fuel at the rail.
