02 mt cat not running

[vern7483]

i originally thought it was the fuel pump, so i hooked my pump up to a battery and it pumped fuel. i then rehooked the electrical connection to the pump, and pulled the motor over, and got fuel. so i am thinking maybe it could be a bad injector, or wiring for the injectors. any info on what it could be would be helpful. also, if anyone knows what the ohms reading would be on the injectors, so i could test them, would also be helpful

thank you

injectors

You can check the injectors with a 9v battery from a smoke detector etc. unplug them make up a couple jumper wires, you should here them open when you put power to them.

maybe i'll try that....i tested the injectors and the were both 2.5-2.7 ohms

got spark? if both ohm reading are the same shouldnt be the injector might be plugged but should still be good

ive got spark.....if i put gas in the cylinders it will fire. its weird, cause it happened all of a sudden....it ran when i put it on the trailer. pulled it to the mountains and then it wouldnt start.

You should get a "Arctic Cat Snowmobile Workshop and Repair Manual" 2002. Use your favorite search engine to locate a PDF file.

There are a few sensors and coil tests that could be good to do. I think you may have a bad ground connection or some kind of damaged wires.

Check connectors and wires before starting to replace to many parts.

I know this might sound to simple but check the suction hose on your fuel pump.
