Posted this elswhere but I've been getting a fair amount of PM's on this.
Sometimes when the fuel lines are removed, the engine is pulled, fuel fiter is replaced or the tank is drained or run out of fuel, it may be necessary to prime the fuel pump on your 2005 -2009 CFi Polaris.
There is a fuel prime plug in the harness... to prime the system takes less than a minute on digital wrench by your dealer... OR you can do it yourself with any 12volt battery Run +12v to the red wire in the fuel-prime plug, (-) 12v to the brown wire in the same plug, listen for the pump to run for a bit.
Also handy when replacing the fuel filter or anytime you bleed the lines.. or that after summer first fire up and the system has lost pressure. Also handy for when you need to put fuel stabilizer in the system.... this will circulate the stabilizer thru the fuel injector rails and back to the tank.
Add 12 volts to the fuel prime and viola.... starts right up. Sometimes the check valves in the fuel pumps aren't the best and the residual pressure in the injector hoses bleeds back... a bit of residual pressure is what makes the CFI sled easy to start as all that needs to happen is to have the injectors "fire" and then it starts up energising the stator fully, and spinning the fuel pump up to pressure. If you find this to be the case, where the sled is difficult to start and your sled is still under warranty, have them fix this problem... They will probably need to replace the whole tank/pump assembly as they are not sold seperately (at least in 2007... The 2008 pump assy is available seperately!)
If you ride with a bunch of other CFI Polaris'... keep a "fuel prime" battery in your trailer/toolbag... A 12volt R/C car ni-cad pack works great for this... Though any 12volt battery will do.
You could also use this to power up the MFD. (unplug the headlights)

Get a couple of the charging plugs too.. One to splice into your sled... the other to charge the pack with a 1 amp or less trickle charger..

If you run your sled out of fuel, you could be pulliing for a bit to get it started and primed.
If you run the sled out of gas and are priming the system... let the pump run for 20-30 seconds on the prime battery... this will circulate the fuel thru the system, into the injector-rails and back to the tank.. self bleeding system... Like on a modern car or truck (gas engine)... the car/truck has a battery however and you can hear the pump running.
On a batteryless system, the CFI/EFI depends on the residual pressure in the lines to supply just enough fuel to start the motor... then the stator takes over and supplies electricity to the fuel pump to run the sled.
Some CFi sleds can get difficult to start if the check valve in the pump that maintains the residual pressure gets gummed up.

On the 2005 900's and the 2006 700/900's
On the 900's the Fuel prime connector is up by the steering column... next to the diagnostic link.
Same prime technique...
I've also had a bad chassis power-up relay... stuck in the closed positon that caused problems. This allowed the little bit of power that was produced by the stator to bleed off thru the headlights and not allow it to start.
