For as long as i can recall,when i turn the key the f/pump would click click click for several seconds then stop....as of late, i get one click maybe two,then stop, but bike ran fine. Today,no click and bike hardly ran (like on 2 cyl) Last test...i undid the line going into the carbs and turned the key, checking flow with zero back pressure and nothing. Dead pump for sure,yes. thanks

I'm currently wrestling with a similar problem on my '91. Haven't run it for over 2 years, which is why I haven't been around here for a while.
Before jumping to the conclusion that the pump is bad, check that it's getting a full 12V. You can do this by pulling the fuel pump relay connector. Connect the positive lead of a voltmeter to the red/white wire (red/black on B models) and ground the negative side to the frame. Turn your keyswitch on, you should be getting 12V. If it's not at least close, you've got dirty connectors, and cleaning them is the next indicated step before springing for a pump.
I did this yesterday and found that I'm only getting 9V -- at the moment I'm trying to generate the ambition to tackle this chore.
Hope this helps...
randy at rpm sells points sets for fuel pumps, and most likely fuel pumps too, , randy for president :flag_of_truce:
thanks guys... it is getting power as i can hear it trying to do something,like half a burp, Test lite into the plug shows current as well. Ordered the airtex from amazon, in the link above from micah360. thanks again.

Steve!!! How the hell are you??? Thought you sold it and moved on, so good to see a post from you. PM me with an update to prevent a ThreadJack...
I have a 1990 FJ1200 and it has no fuel pump.Turn your 91 into a gravity fed FJ and you dont need a fuel pump.Works for me I can swap carbs from ny 85 to the 90 and vice versa for testing.
