If it does turn out to be the Roll over sensor, it can be by-passed or cheated with a voltage devider... A couple of resisters, easy. But it SHOULD reset once righted and a restart , as mentioned above. It will NOT give you a code if it has "tilted". You will just notice a shorter duration of the fuel pump priming when the kill switch is set to run. You WILL get a code... 1-5... if there is a problem with the roll over sensors circuit. Like a bad wire, or an unplugged sensor....
