Your engine codes should only be in two digit numbers and you should not have codes that end with any zeros.check engine light should flash like count the flashes three flashes pause then 6 flashes would be code 36 then longer pause between codes then you have more than one code after a long pause it may flash 4 times then short pause then two flashes would be code 42 witch is engine coolent temperature high voltage a code 56 is fuel pump open load/short to battery or short to ground should start with one flash short pause then two flash meaning 12 then codes will repeat ,to start flash engine codes turn key off and on three times in less then 5 sec then leave on

Need to test to see if power is being sent from the key switch to the ignition I would think bad fuse or bad ignition switch

Polaris ATV | Answered on Nov 13, 2019


You have lost power to your ignition when it is in the on position check fuses or look for broken wires leading from ignition switch it could very well be in the switch it self

Ok the 6 amp fuse is for the ecm the 15 amp fuse is for the cluster one of the 20 amp is main power the outher 20 amp should be for the starter and charging circuit .your over heating problem could be in the fan temp sensor you will find it on the left side of the machine on top of the thermostat housing , take and disconnect the plug on it and jumper the two wires togather with key on fan should come on if it does replace fan temp sensor .if not visibly pull each fuse out and look to see if is burnt odds of the fan being bad is very uncommon. This will be all good if is an EFI 800 hope that is helpfull

define "stopping". If it involved using the new ignition switch, then I think a return to the dealer is necessary. You know it takes 3 times for them to get it right?

Polaris ATV | Answered on Oct 16, 2019


Here is a link to error code sheets. User manuals do not offer the codes. Service manuals and the dealer has such. But the link in this forum posting should offer codes for the 800. Links are also provided for other models.

Odds are your carb needs to be taken apart, cleaned, reassembled and adjusted if needed.

Have you checked the Crankcase seals? I have 2 Big Bosses with 250's. 1989 + 1992

Both were terrible at starting and idling....after much troubleshooting I finally changed the crankshaft seals. (Which btw looked fine from the outside!) machines can be Cold now and will start 2 or 3rd pull with the cord now. Idle perfectly.

Also the oil injection system stopped working intermittently. Machine would just quit.....crank and crank it forever. So I just started using 32/1 mix and unhooked the Oil Injection cable from the Throttle.

after unscrewing bolts around pump housing unscrew screw on impeller backwards thread then twist off impeller regular thread holding back of motor shaft remove impeller then remove 4 screws holding motor to housing you will need a new seal and o ring for shaft if motor overheated probably distorted housing and may leak less hassle replace whole pump
