I am experiencing the same problems that he is... i replaced the filter on it, and it started a few times but it wont start unless i put some starting fluid in the air box... i need help cause its sleddn season and i have no way to get my sled to the hills... anything at this point will help... the dealship says that i need to replace my injectors, but it runs great once it starts... HELP

 

what kinna fuel pressure ya showin?

 

I havnt checked my pressure, but i was talked to a guy today that told me to check/change my lift pump??? i dunno, how do i check my psi??? sorry still learning!!!

 

you need to install a fuel pressure gage..............you can rig one up temp but just do it right the first time and get a good gage

I dont have much confidence in the original lift pumps............they are **** poor at best

sounds as if you are having fueling issues to me

 

fuel issues i agree... i will put one together tomorrow at work and check my psi... thanks for the hints!!!

 

Your injectors are bleeding back too much. Need to have them tested and fixed.

 

Any mods done to the engine??

 

just a bully dog pmt... think its the injectors huh

 

Yup, had the same thing happening to a guy out here and that was the problem.

 

03's were famous for pooping injectors.
