Could someone advise on how to test to see if the fuel pump on my 90RR is functioning?
Thanks!

You should be able to disconnect the fuel line (at what point in the line I don't think it will matter) then switch the vehicle on, you should not have to crank it just turn to the ACC position, this should activate the pump and shortly afterwards gas should begin to pump out of the fuel line.

 

If you don't like this idea when you turn to the ACC position you should be able to hear the pump, pumping fuel.

 

I can hear the fuel pump if that what it is - the buzzing sound that runs for about 6 seconds when the ignition is turned. However, I am tryiing to diagnose if the fuel is actually getting pumped all the way to the injectors or if it is clogged at the fuel filter. Thanks again for your input!
