Fuel Pump Testing Procedure. Written by Dave Forgie Quick fuel pump function test - for those that might be needing one. Posted by: UrS4boy on 2005-10-27 08:16:03 If you have starting problems and don't know whether its the cam position sensor or the fuel pump, you can at least confirm that it is or isn't the fuel pump. Sean Douglas (quattro20v) and I used this technique to test our fuel pumps for delivery rates before we developed the fuel pump relay procedure in July/Aug 2004. To test the fuel pump, you need a long length of wire with a spade connector at one end, an aligator clip on the other end and switch somewhere in the middle - but closer to the spade connector end. Once you have that, you need to open up (break) the inlet connection to the fuel rail (hard piping and braided hose on the driver's side (left hand drive cars)). There may be some residual pressure so only do this when the engine is cold (not a problem if you can't get it started). You need to get a four foot long hose over the connection from the fuel pump.
