About 6 months ago I had a new fuel pump, ECM, stator and heaven only knows what else installed on my 05 King Quad.  It has been running great until the other day when I went to get it off the trailer, and it would not start.  Pulled the plug, and it was a little dirty, but not bad, but I put a new one in just for good measure.  Still would not start.  Pulled the fuel line connector underneath and turned on the switch and fuel was coming out, but with little to no pressure.  I turned the switch off and on multiple times to fill up a water bottle with fuel, and the fuel was good.  As it turns out, the fuel pump is out of warranty (go figure).  So, I'm going to put a pressure gauge on it tomorrow and see what it is pumping.  Is there anything else I can check?

Many thanks,

The fuel pumps have diaphragms that crack sometimes.   We have also  seen new pumps installed with problems.  It’s weird but they do fail more so then the manufacturers like to admit.  I would swap it out and see how it goes.

I appreciate the response.  I fully suspect that you are right, and I have already located another.  It is just such a pain on these to put in, because there is so much that has to come off before you can even get to it!!

Many thanks!!

Yes it is, but for an 05' it only has 370 miles on it.  It is my primary means of getting around on my property since my electric wheelchair just won't go where I want to go.  Oh well, such is life.  Thanks again!!

Are there vacuum hoses other than the primary fuel line???  Recommendations on what else to check???  The local Suziki dealership will not help because it older than 10 years old.  So it is me and the Polaris tech and he knows much more than me, but probably not as much as you regarding Suziki's.

It is fuel injected, and the pump does come on.  We pulled the fuel line and each time I would turn the key to the on position it would pump fuel.  It is just not pumping at 43 psi, I am almost certain of it.  What photos would you like to see?  It will be tomorrow morning before I can send anything to you.

Ok I thought it was a vacuum pump.  No pictures needed. So that new pump is an oem or aftermarket? Have you primed the fuel lines and checked that there is no obstruction coming from the tank ? 

Was it a direct replacement and plug right in?

It is an OEM pump that was put on.  Each time I turned the ignition on, fuel would pump out, but according to the specs, it is supposed to come out at around 43 psi.  I was able to put my thumb over the line, and no fuel would push past.  The tank was clean before the new pump was put in.  I am running 100% ethanol free gas in it, and have been doing so for a while.

I would go back and look at the intake portion of the fuel system and check that  the petcock, supply lines are clear and no cracks in the lines where you could be sucking in air. Take the fuel pump off and bench test it also if you can.

I’m not 100% familiar with this bike but if I’m not mistaken theres a screen inside the tank on the sending unit.   I would pull the tank agin and take that sending u it out and double check all of this.  Did the pump come with a screen ?

Put the pressure gauge on it the King Quad, and initially it was reading right at 30 psi.  Then bled some of the fuel off, and it went to about 43 psi, and after a few minutes was running like it should.  Then I discovered that I have a broken left rear CV :(  But it's running :) so I have to figure out who sells the best CV's for it.  I am going to replace both, just to be safe.

      How did you get into Quads?
      By Mikey69
      Heres my story. Kinda long. I guess I was a late bloomer when it comes to quads. I had never ridden a quad in my life. Rode Dirt Bikes as a kid growing up. Back in Oct of '06 I found a Mustang on craigslist. Took it for a test drive one morning before work. Fast car. 351 Cleveland. I had planned on meeting the guy again after work. For some strange reason thats still to this day beyond me, I stopped in Hillsboro MotoSports on the way home from work. I had 6 Grand on me. There was a left over '05 sitting by the front door. It was on sale for $4999. It was $5499 OTD. I didnt even look at anything else. I knew nothing about quads accept I thought it really looked coool and I had the money in my pocket to buy it. I was sitting on it when the salesman walked up and asked... "Can I help you?" Without hestitation I pulled 60 Ben Franklins outta my front pocket and said "I want this Quad. Load it up in my truck." It was just about dark by the time I drove away from the shop. BTW, I didnt bother to ask my ol lady if I could buy it. LOL. Anyway, I took it by the house and showed her. She was kinda stunned but not mad. We drove over to a friend of mines house and unloaded it. I took it to the field across the street from his house. HOLY CHIT!!!!! I was surprised by the power. I had it for about 2 weeks and took it to Sand Lake. I was there a few hours and rolled it on a banked turn at the top of the bowl right before you get to the one-ways. When it rolled, I flew off and landed on my belly. The quad came bouncing and landed on my back. For a month I couldnt even walk. I was scared of it. I considered trading it for a 250EX. Went back to the shop. The salesman said..."Dude!!! You dont want a 250EX!!! Trust me. Just get used to it" I still wasnt convinced. I put it on craigslist for $4000. Calls were coming in. I had a guy that wanted to come look at it that evening. I decided to take it for one last ride at Browns Camp before I sold it. I was still afraid of it. After about 5 minutes I started feeling comfortable on it again. I decided right then, I loved my Honda 450 and would learn how to ride it instead of selling it. That was late Nov of '06. Work was slow for a Painter in Oregon. My new job everyday? Going to Browns Camp and ridding my Quad. I bought my Girl Friend an '02 Blaster. I rode my 450 for 4-6 hours almost every single day for 3 months. And yes, I know my way around Browns Camp pretty well. LOL. In March I bought her an '06 TRX250EX (Thank God I didnt trade my 450 for one of those) LOL Since then, I have become totally addicted to quads. I love them. Couldnt imagine not owning at least one quad. Luckily I have two. My "07 was $6500 OTD in July of '07. Bought it for my Girlfriend. Traded in her 250 EX. A month later we broke up. So, I wound up with two Honda 450's.

      My first trailer project.
      By Frank Angerano
      So I decided to pick up a small trailer if I could get one for the right price.  I found this one for a few hundred bucks on Craig’s list.  It is  a galvanized trailer which is exactly what I was looking for. The wood was shot and needed some minor repairs which I could care less about as long as the chassis was good. 
      I striped it down and put a new deck on. I had some vinyl realtree graphics that I had laying around so I added them to the fenders which I think worked out well. Very happy with this little guy.  
      I'm having the iron workers at my jobmake me up a few lightweight side rails that will have a 22 degree bend in them to accommodate the tires that slightly hang over the edge and will incorporate some tie down points as well.
