2008 Suzuki king quad 750 fuel pump relay

Recommended Posts



Why would you have to convert to a stronger relay ? 
Is the existing one failing ?
A relay is pretty straight forward except for the manufacture brand, that’s where the quality is. Bosh makes a good relay and a few other brands.

I have3 of the stock fuel pump relays and my bikes fuel pump will not run with any of them.I used a better made relay and it would work for a little while and then it will go right back to not working.

My guess is that the power going to the relay is either not getting the proper voltage  to hold it closed.  Or it’s have a pulsing voltage that’s allowing the relay to not fully close.  

lastly I would check the ground and make sure it’s tight.  

Either condition will allow the contacts inside the relay to arc when they spot fully close and destroy the contacts hence a bad relay. 
So start by checkout voltages first and move on to grounds etc.

      Ok, so I bought this scream of a deal the other day - a 94 King Quad 300 for $40.00.  It's been sitting outside with no carburetor on it for about a year.  Its rusty, missing some parts, wiring is all cut up and spliced etc.  No seat, no racks but the plastic is all there minus the headlight housing.  Anyway, who can pass up a $40.00 quad right?  I get it home and looked at the sight glass for oil level, it's about 1/2 oil and 1/2 water.  I drain it, refill it and turn the motor by hand (recoil starter is missing) and it turns over just fine.  I worked on the wiring for about an hour and got it to turn over with the electric starter and got enough of it sorted out to get a spark.  Did a quick compression test, 70 lbs.  Wet test bumped it up to 90.  Ok, so rings and cylinder washed out with water for a year, not too surprised.  I thought 'what the hell' and sprayed some starting fluid in it and it ran for about 2 seconds - enough to show  it's got life.  Since then the compression has gotten worse, I can't get enough pressure to activate the carb diaphragm, therefore no fuel pump either.  The compression is now around 60.
        Anyway, my question is....is it worth it to try to get this thing going?  I tore the top end down today and the cam and one of the rockers is pretty worn.  I figured a top end job would be about $100 or so, depending on the condition of the cylinder but I'll probably have to put a cam and rockers in it as well.  Doing some research on ebay I figure I'll have to spend about $500-$700 to make the whole machine right again.  Much less just to make it run and use as-is but I won't really like it until it's right.  I don't mind doing the work, I actually enjoy it but I'm concerned about what all that water did to the rest of the internals, I can't really test it all out until I can make it run.
      I know it's a basket case but I'm not into it much at all, even if I do the top end and find something else wrong I'm still not out much.  I'm leaning toward ordering the top end parts and going from there unless you can convince me otherwise - any way to check the rest of the internals without tearing it down?  I plan on flushing the oil cooler before I do another oil change, I've drained it twice now and it gets milky almost immediately just turning the starter - I suspect the oil cooler is polluted badly.
       
      I'll get some pictures today if anyone want to see them.
       
      thanks!

      Hello! I picked up a YFM400 and I would love to talk shop with knowledgeable co-owners, and I'd love input about the machine from anyone here who clearly knows more than I do! Cheers from NY

      Working on a 2002 Quest 500 and the grommets in the tank are rock hard and leak.  Any tips on replacing without having to pull the tank, hands are too big to get to the bottom gromment which is the worst one.

      posted a while back - it was running at one point - I have all the plastic shroud off - it's down to frame and engine now
      -fuel pump: when line from petcock is attached, no fuel comes out other side to carb; the line to the carb is open (can blow through it); I thought when I cranked engine that the pump would spit out fuel on other side but it does not; I removed fuel pump and opened it up - diaphragm looks good - but internal areas had lotsa calcification build up - I cleaned this out and dried it good - the clear plastic pieces (?diaphragms) aren't broken - the spring w/ steel ball on end moves freely; am putting it back on tomorrow; but can anyone answer about the pump? isn't it supposed to pump fuel through it... to other side... to carb? puzzling
      -along with fuel pump: I replaced petcock 3 weeks ago (gas tank had rusty fuel in bottom - cleaned it out prior to new petcock); when I turn petcock arrow NOT to on or reserve, fuel comes out of line; when I turn it to on or reserve, fuel doesn't come out; puzzling
      -I don't know what's on back of fuel pump - it's a valve that has a hose coming out of it - looks like it goes to engine/carb - I haven't traced this out yet - what is it?
      -can squirt gas on air filter and engine will run for 2-3 seconds then stop - fuel in top of carb (under diaphragm) does same
      -it likely needs carb rebuild - will get to this - but something isn't allowing fuel to get from fuel pump to carb
      -I THINK it has a mikuni model x carb - diaphragm is ID 26mm  OD 68mm - hard to find inexpensive diaphragm, I guess because it's a model x
      -last thing - I replaced solenoid due to old one clicking; I HAVE to be charging the battery or it won't start/turn over - battery just goes dead; but if charging, it'll turn over nicely; i'm guessing it's a bad battery
      -any help appreciated - I've never owned an ATV before - inherited this beast from grandparent in-law

      Looking to purchase a windshield for my ATV, suggestions of what to buy with quality in mind and will fit without doing any modifications.

      Doesnt seem to make the sound all the time. Mostly does it under load or going up an incline. Its kind of like a clunk and or grinding noise, Kind of hard to decipher. Today while going up an incline it actually stopped and it sounds like something spinning and then it ingauged again and it would move. I checked the clutches and installed a new belt before it did that also. Rear drive shaft seems ok where U joint is too. Has all new rear CV shafts and bearings and al new bushings in rear arms. Also flushed out the rear Diff with no shavings. Any ideas or where to check.
