If you have a spare Ion handy, it may be worth switching bolts and trying then, to eliminate the bolt as a potential problem. You could be getting a bad case of bolt stick - which is unlikely if it suddenly cut out - but worth checking nonetheless.
So did it just stop firing during a game? have you checked the trigger, i had this happen on mine for some reason the trigger would be fine to start off with then the part that strikes the switch on the board would stop hitting the switch must move forward or the trigger moves. Take the grips off and try to fire the marker by manually pulling the switch yourself (i.e. don’t use the trigger!) if that works you will need to look at the trigger.
how long you had the ion mate?? and do you have an on/off on for the air??
try another air bottle on it as the pin might not be conacting and opening valve properly. seriously check all the stupid stuff it will not be somethin serious as there isn`t really anythin serious to go wrong with an ion barrin reversin your car over it
Put your finger in the breech and then fire . It's most likely an eye problem. BTW - I was joking about the finger in the breech - but try the board and eyes on their own.
Oh - and strip then clean the solenoid - it's probably got jammed (ignore the clicks).
can you hear any air bein released when the noid clicks? mine done that before stripped down and the bolt was stuck back. push forward and never had a problem since
