Question issue starting the bike after winter - April 10, 2010, 12:21 PM

Ok so I stored the bike (96 zx600) for a few months and went to start it up about two weeks ago. It started right up with the choke and ran for about three mins and cut out and then would not start again. My first thought it carbs are gummed up. so I pulled them off cleaned all the parts ( which were very clean already), i drained the gas and put new fuel in, i changed out the spark plugs as well. the battery is charged (its less than a year old and has been on my trickle charger as well).

none of this worked, still cranks but will not start. so next I check all the fuel lines for clogs and found none. Today I unhooked the fuel line that goes into the carb and put it in an old gas can to catch fuel coming back through and I rigged a little gas on the filter end to go through the pump. when I try to start the bike the fuel did not come out of the fuel line at all or the other end of the pump. Does this mean my fuel pump has failed or it is a different issue? Pump does not really make any noise when i try to start it but I can't remember if it did when it was running or not either. Any help is appreciated.

Good job on diag. Sounds like you need a fuel pump. Have you checked electric to pump? Fuse, faulting wire, bad ground... I would get a test light and start pkoing. Is there any safety feature that would cut the fuel pump?

I have not checked any electric to the pump yet, misplaced my test light and have no idea where it is haha. I checked the relay fuse and it seems fine. Im not sure if the pump itself is grounded or if it is grounded through the main harness. I also do not think these is a safety feature to cut the pump, but I am not totally sure.

well i hooked the fuel pump up directly to the 12v and it started making some noise and sounded like it was pumping. It was rather loud though and the noise was kind of like a quick paced popping sound. I do not recall it sounding like that while the bike was running normal. Does anyone know if that sounds healthy or is the pump bad?

edit: sounds like this http://www.youtube.com/watch?v=e8m01...eature=related

Get a test light and see if the fuel pump is getting power.

Also if you already have fuel in the carbs the pump will not run until it needs to.

I may just order a pump becuase it sounds different then i have ever heard it while on the bike. I was just curious because when i hook it up off the harness it makes noise like its pumping but its just louder then i have heard before. The carbs have no fuel in them becuase i took them apart and cleaned them. I also have had the pump disconnected from the carb to see if it would push fuel and it did nothing while plugged into the harness. I was under the impression that it would also prime each time you start the bike to make sure the correct pressure was there.

ok i did some more poking around and tested with a multimeter. Im getting 11.6 or so volts to my fuel cut relay which is about normal from what ive read. At the pump connection, however, i am only getting 8.3 volts when i crank the engine. This should be getting 12volts correct? Any idea where it would be losing voltage between the relay and pump connection?
