Hello 12, the blinking injection light is the diagnostic EFI light telling you there is an error code or problem. Unafortunatelly the only way to errase the faul is to fix it and then use de PDA sacanner tool to errase it. But you can check what is the problem by counting the blinking and check the error/fault code. To do this you have to look for the ECU diagnostic plug wich is located in the front of the ATV where all cables and plugs come together. Look for a 3 wire unconected plug with wires red,Purple, green. you have to ground the Purple wire 2.5 sec after the ignition is on. This is call the ECU MIL code trouble fault. To read the code proceed as follow, Turn the ignition on, grond the ECU wire 2,5 sec after. The injection light will flash for example for 0, 10 times intervals, for 1 one time, 2 to times and so on. If there is only one faul it will give you a 4 code number by blinking, if there are more faults it will give you the second one after it finish the first 4 ones codes. After you shoud come with a nuber like 0203 for example wich is the P-code so you will have code P0203, let me now what code you have to see the error code.
