First thing I would do is to CHANGE the fuel filter and check your Fuel Cap is sitting in properly and that there is still a rubber sealing washer on it.

I had my car keep trying to stall once... I changed from unleaded fuel to premium fuel then and have not had the trouble since...

However my fuel filter was blocked in 6 months using unleaded and last time I checked it since using premium it was fine meaning it has been in there more than 12 months now...

Cheers,
Tim

if you suspect water in the fuel put like 100mls of metho in it, that should kill the water. Also change ya fuel filter.

Simple test is to take it off and blow through it (in the direction indicated by the arrow)...

If its easy to blow through then its good... If you feel yourself going red in the face, you can imagine how the fuel pump feels... A new one has pretty much no restriction to air passing through it when you blow into it...

Make sure when you re-install it you get the arrow the right way otherwise you'll then find your injectors blocked...
