    2001 Polaris Tx will turnover / crank but will not start

    I have studied the excellent posts / stickies on this site and have followed all the advice I could gather. Currently I am stumped.
    When ski is running it screams – however it will not always restart after riding after 20 minutes or less.
    Symptom engine will turn / crank but will not start
    1.Battery was weak and replaced it
    2.Noticed Bilge pump was ON when system was off / lanyard removed – Always running
    3.Next was checking system out trying to start engine. It started cranking however I could not stop it from cranking. it continue to turn over with lanyard removed and start / stop pressed.I had to disconnect battery to stop it
    4.Checked and cleaned Start / Stop PBSW no issue
    5.After reading and researching – I concluded the LR-505 was shot and the Starter solenoid was also bad
    6.Received very cheap replacement LR-505 Aftermarket part from ebay ($25.00) and replaced old unit
    7.Also replaced solenoid (was old one with metal tabs) with new recommended model (all plastic)
    8.Put everything back together and tested with the following results:
    a.System cranks but does not start – However New solenoid fixes ON/Off issue
    b.Bilge Pump – working correctly except I can’t verify its working when running
    c.I noticed that there is subtle difference in how engine crank sounds with lanyard removed vs. installed so I think that feature is working.
    9.Any suggestions or ideas– CDI Ignition – fuel pump – other?
    Thanks

    Press and hold the Bilge button. Does the engine now start?

    Disconnect and bypass the LR-505 module.

    Just bypassed LR-505 and behaves the same; system will crank / turn but will not start sounds like / acts just like it did when it was connected to LR505.

    Thank you

    Leave the LR module bypassed. Hold down Bilge button. Does it spark or start now?

    Ok I held down the Bilge pump button and no start - it cranks but no start or sputter -
    How do you test for spark?
    I am thinking bad CDI or perhaps no fuel to the cylinders?

    To summarize
    Replaced Battery
    Replaced solenoid
    Replaced LR-505
    To confirm replacement LR-505 was not defective Bypassed LR-505 and pressed bilge to try and start

    Results
    Engine Spins but will not start

    Questions - How do you test for spark - any other areas to check

    Thank You

    Check the spark by putting spark plugs in the spark plug boots and laying them on the cylinder head,then crank the motor and look to see if it has spark at the plugs,then hold bilge button and try it to verify no spark that way as well
