    Thread: VR6 fuel pump voltage

    1. 08-12-2012 07:59 PM #1
      With the key in the ON position I am getting 5 volts on the two larger outside terminals and 5 volts on the two inside terminals, I took the fuel pump out and put 12v to the two outside and it kicked on.. What am I missing.. Any ideas?

      What are you trying to do? The red and yellow wire on the plug is power for the pump. You need to crank the car in order to see if you are getting power.

      Ok as of right now the car is not starting, it gets spark but not enough fuel,

      I checked the relay and it seems to be working, I checked the fuse and it works.

      I jumped the relay and the pump turned on but it sounded like it was bubbling with air but fuel is hitting the rail, I am getting voltage to my injectors but my first cyl spark plug looks brand new, which they are... It does not look like it has even fired once..

      Crank the car and test that red and yellow wire dont use a meter use a test light. Test it while its plugged in.

      On the pump. Is your car mk3 or 4?

      MK3, the more i listen to this video the more I think it is Timing... But my car does not have a timing notch on the gear so I have to use the one in the bell housiing and a cam tool to keep them straight

      Yeah I saw it before. I agree with you it does sound like the timing is off.

      When you recheck the timing make sure cyl one is at full stroke just take out the spark plug use a long screw driver to feel the piston at full stroke then the bottom end is at tdc the time the head. And make sure the cam sprocket blots are tq

      I will rip the valve cover and upper chain cover back off tomorrow and see what the hell is going on, Maybe I will upload some pics of the timing mark.. The cams should be exactlly straight and aligned right? If they are off the slightest will it cause all that clatter ..
