Need help on 2003 800 mountain cat

Been working on a Buddy's 03 800 mountain cat that hasn't been used in 3 years , the driveshaft broke on the clutch side behind the bearing and tore the tunnel. Replaced the tunnel ,driveshaft,bearings and chain. Cleaned the fuel tank and replaced the fuel pickup lines. Then the fuel pump wouldn't work so replaced it too. NOW the PROBLEM is no fuel going thru the injectors, I have fuel to the top of the injectors on the fuel RAIL. Is there any way a guy can clean these.

I can make it run by putting gas in the cylinders but after gas burns out of the cylinders it dies .

Any help would be greatly appreciated.
 
Soak them in a can of carb cleaner for a day, brush them off . You could try putting some air pressure to them to pop them open but I would not put more than maybe 60 or 70 psi to them. Make sure you are getting impulse power to the injectors.
 
Thanks a bunch for the advise, did both carb cleaner and air pressurethen snapped them with 12 volts. Put it back together and fired up on the 3rd pull and hasn't missed a beat.

Thanks Shortman
 
it was the 12 volt pulse that did it. i had to do that on my 03 800 a couple of times in the beginning on the year and like you said 3rd pull and it was running.
