Fuel / Pump Issue
A fuel issue that is perplexing me. 94 ZX11D. I am the original owner with 14k miles on the bike. I rode the bike religiously when first purchased (this is my 4th Ninja over the years). Since I got married 5 years ago, the bike has been riden, a total of 5 times (maybe). The last time I rode the bike (last summer) that bike barely moved, I had to enable the choke completely to make the bike move. The bike sounded like it was running on 2 cyl's. My rig was running slower than my first 50cc moped. I parked it last summer with the intentions of combing through one day.
That day is today. 20 years ago, I was a mad-man for bike maintenance and storage. Today, 2 kids later, from non-use and my poor attemps to prep the bike for long-term storage, I have a list of negative issues that have created for themselves on my rig. The bike LOOKS showroom, but runs horrible.
Fuel is the obvious one right now. I removed tank to inspect. Can anyone tell me when the fuel pump is to operate? Is it continuous? If I crank the bike I get no activity from the pump. I checked the voltage from the connector and noticed that when I crank the bike it only shows 4-5 volts. If hot wire the pump the battery, it runs and spits out fuel. Is this correct? My first guess was that the pump was dead and the motor was pulling the fuel from the tank (hence having to enable the choke) rather than being supplied by the pump. However, as I mentioned prior, if I hot wire the pump, it works. Can someone out there give me a detailed and specific description on the path of fuel for this bike. NOTE: downloading service manual as I am writing this.
Thanks...Paul.
