sled wont run????

09 m1000,slp can and intake. has ran great the whole season so far, i let it sit for about a week and half. i went to go fire her up and it would fire but would not idle, then it would start to back fire pretty bad. finally i got it to idle but it would only idle for about a minute, whenever i touched the gas it would die. I took it out for a little test ride just to see if i could get her to open up, it would cut out at 6 everytime. the next day i completely cleaned the gas out and blew the lines out. there was quite a bit of water in the bottom and also some other dirt and ****. i through in new gas and now it dies at 4600 r's, takes about 12 pulls to get it to idle. what should i do now? i tryed to take the injectors off but the 4 phillips screws will not come out of the block without stripping them, i even tryed and impact driver and that wouldnt work?? has anyone had these problems???
 
ive noticed on my new '09 m1000 for some reason or another it will when i first start it up it does exactly what you said it does... it starts on the second pull but then it idles real low and as soon as you touch the gas it dies. pull it again then it runs fine and stays running for me. so not sure whats the matter.
 
hmm, also forget to mention one of the spark plug wires has been touching the engine block and it burned through the rubber all the way to the wire, it made a few sparks, i checked for spark in all of the wires and they all had spark??
 
the plug wires dont burn but wear out from vibration, I put a protector on mine and watch them. have you put new plugs in. If that doesnt do it, check your power valves, barometric pressure tube and wiring. is the sled warm and dry?
 
I would check your powervalve cables, make sure that they move freely and are opening. Will it rev with the belt off? Do the plugs look good- light brown. Could be a short in the kill switch or wiring to the switch. Might be able to disconnect the switch at a plug and see if it runs better. Check the wiring harness behind the plate that covers up the steering stem mount. Should be two nuts showing that you can take off to remove the plate and let you look at wires. I've seen the wires smashed and broken under the gas tank, but usually if those wires break it puts the sled into limp mode. Which would make it not rev but wouldn't make it back fire. Pull the pipe and look at the piston make sure it isn't scratched up.
 
might no be a bad idea to put on fuel pressure gauge and see if it building enough pressure, there was crap in the fuel there is a chance that its not getting enough fuel, If it takes 12 pulls to start it may just take that many to get enough pressure built up.
