I have the same sled and have replaced the injectors a few times, or I have a few sets.

Are you getting any flashes on the ECU to denote the injectors are failing?

2 long and one short would be the flywheel side.
2 long and two short would be the PTO / clutch side

If you prime the cylinders does it fire at all?

I'd check the traingular plug and make sure connections are clean.

I did prime the cylinders and it did fire...but would not stay running. No fuel getting through the injectors, or the fuel pump doesn't have the psi to activate the injectors...I dont feel like buying a new fuel pump @ $200+.

Just going to change the cylinder to convert to carbs!

Converted daughters EFI Indy to Carb. The EFI was to hard to figure out and could be too many things that would keep it from starting....... made and all required modifications to convert....got fuel and spark and SHE FIRED UP!!!

Still have not taken it for a test ride, still need to install "Pink" shocks and "Pink" Boggie wheels.

Test drove daughter's sled tonight...she ran like a RAPED APE!!! Almost hit a dumpster. Throttle response is on the money, idle's perfect, just doesn't like to stop on ice packed snow.

Only thing left to do is get the seat re-covered, then post pics on here.
