hi im new to this, i wanted to try and get some help figuring out what might be wrong with my raptor 7oo. here is the problem... the quad will turn ovr then stall right out. i put fresh gas, i have good spark, fuel is gettin to the cylinder, and the thing just doesnt want to run. the fuel pump is working properly, i just have ran out of ideaas and i dont want to bring it somewhere and get a run around, had bad past expereinces,. but if any one has had a problem like this with the raptor 700 or another fuel injected atv. let me know what the problem was. thank you

 

The only real issue any of them had was with the TPS (throttle Position Sensor). You can do a search and probally find lots of info on it.

Only other thing I would try would be to disconnect the battery for a minute to reset all the sensors, that and replace the plug. Some people have issues with fouling plugs (i have never fouled one) mainly from starting and stopping them to much before they warm up. Also giving it gas while its warming up can do it.

Also have you done any performance mods without adding a FI controller?

 

yeah i have a power commander, pro design intake with the air box lid off, two brothers slip on and a hot cam stage 2. i un plugged the power commander and hooked it back up to stock to see what would happen and it was doin the same thing. i thought that it would be the tps sensor also. im gunna have to try and disconnect the battery like you had mentioned, i never thought of that.
