Yes, that is what it is about, but 1 thread asking the question would have been enough.
Maybe no-one knows the answer to your problem.
Have you taken it to a dealer and had it put on STAR?

try this article here. http://www.whnet.com/4x4/badgas.html

Have you tested the voltage to the pump once the car is started??Is it 12v? If the pump is rated at 12v you could try wiring a direct 12v supply from the battery after you remove the normal one. this would at least rule out the pump as the cause. Make sure the pump has a good return path ( earth??)

As Grober

though you may only have 5 volts on the pump,,put the minus lead from the meter to a good ground point and then measure both leads and only one should have the 12 volts.

If they both have a voltage then the earthing ground is bad for the pump.

I cant send out diagrams as they will not print out
