    zxr250 no spark

    hi guys
    I have recently picked up a 93 zxr250c. the problem I have is a severe leak of spark, ie nil.
    I have been led to believe these have an immobiliser as standard. is it possible to bypass the system?
    everything else appears to be working ok. The coils have power but don't discharge. Any help would be appreciated.

    No switches in system that prevents it from starting?
    Like sidestand/ clutch? ....
    Your run/ stop switch on handlebar shorting?
    Opinions are like arseholes: Everybody has got one, but that doesn't mean you got to air it in public all the time....

    run /stop switch works ie no crank with switch off
    side stand switch not working, cranks with stand down, and in gear
    clutch in to crank
    how does the crank angle signal work?

    Have you tried a (known) good plug to confirm there is no spark ... ??

    I have tried another spark plug on both coils. Does anyone know if the ignition modules give problems?
    A workshop manual would be helpful but it seems to be hard to find in English. even a wiring diagram would be good

    I followed the link and it charged me $49.95 and then couldn't find a match for the manual.

    I decided to bite the bullet and opened up the ignition module. bad news. it has been wet at some stage and is stuffed/ rusty/ mouldy
