I was dragging some small tree branches yesterday and my grizzley 700 (EFI) backfired and died. Until that moment, it has run perfectly since I bought it new. It restarts but doesn't want to keep running. After sitting for an hour, it started, ran for 30 seconds and then died again and was harder to restart. It has less than 200 miles, has never been in water, and has good gas in the tank. I called my dealer and his guess was the fuel pump. I don't have a service manual. Is there a fuel filter in the fuel line somewhere? Is the fuel pump in the gas tank? I will probably buy a manual; are the aftermarket ones good enough? Yamaha wants 80 bucks for theirs. Thanks in advance for any replies.

The fuel pump is in the gas tank, it is located directly behind the filler cap under the plastic. I would test it before you replace it, your problem could just as easily be the fuel injector or the throttle position sensor, or something else. A repair manual is definately a good idea because it should have specs and info that you can use to test some of the possible problem parts and it will also have a troubleshooting guide that can help you diagnose your problem. It is hard to find aftermarket manuals for newer machines, so I think the factory manual is going to be your only option, but it is the best way to go IMO. Ebay has the factory manual for $75, but you have to pay for shipping, so you may as well get it from the dealer. What I would not get from the dealer is parts, when you get ready to order parts, check Babbits Sports Center, Service Honda, and Bike Bandit. You will save alot of money on the parts by buying them from an online retailer, and they have the same OEM parts that the dealer will have. Good luck.

Wish I'd bought the extended warranty. My last Yamaha (350 Moto4) went 20 years with no service problems. New fuel pump is over $400.00; guess I'll give the dealer some bucks to find out what's wrong. Thanks for the replies.
I would get a manual and try and diagnose the problem yourself before letting a dealer rape you and maybe replace a few things that don't need replacing before they get it right. Just my personal opinion, I would never, take my quad to a dealer unless I wasn't paying for it. Just too expensive. Ether way, good luck. BTW, another thing I won't let a dealer do is sell me parts. Like I said in the last post, an online parts retailer will save you money. Service Honda sells the fuel pump for $309.69 + shipping. Here is a link to the site, check them out. You can look up the part by entering the part # 3B4-13907-10-00. You can also look up the machine on the micro fische, you will need to look it up by the Yamaha model number, the bigger Grizzlys aren't listed as such, just by the model number.
