    1993 Polaris Indy 500 SKS EFI just wont start.

    So...
    Bottom line, we are looking for the manual for this sled. For Free preferred.

    Any help would be awesome.
    Here we are again it seems w/ the mystery of the EFI that wont start. My father-in-law and I have been working to fix his sled all week. Replaced spark plugs, Cleaned injectors, checked fuel pressure (31PSI), ran wiring diagrams. Still nothing.

    Cheers,
    T/O

    Does the fuel pump cycle on the first or second pull?

    electric start, but we hard wired it as a test to check its function... the old fashion way. It got a little wet... manahmanah.

    Check the voltage regulator thingy ( I can't remember what it is called).. that is the component that wakes up the fuel pump and ecm on start up.. I had to re-engineer mine because the part is not available.

    Fuel pressure needs to be between 35 and 37. You'll find the service manual here.
