    05 rxp will crank but won't fire up

    My 2005 RXP will turnover but will not fire up. I don't get any error codes when I do the self diagnostic. I am getting fuel and spark. Thought it may need to have the closed throttle and idle actuator reset since I did take the throttle body out and removed the TPS so I could grease the butterfly shaft.Took the ski to a friend who has the Candoo and he did the reset. Engine still won't fire up. He was able to get a P0505 code which is an issue with the idle bypass valve. I checked the resistance between pins A & D and pins B & C. Both values were around 50, as they should be. Any ideas as to what could be the problem. I realize that there could be a mechanical problem with the piston in the idle bypass valve. Did anyone ever find that valve in a Bosch or VDO part number? The BRP part costs $187. Ouch! Also I don't know why I can't get an error code when I do the self diagnostic.
    Any help greatly appreciated.

    I've tried giving some throttle, but it still won't fire up. Still I don't get any error code.
