THat relay gets it's signal to connect from the start button. It can hang up and go bad. I would also test the starter button as it may have a short in it causing the relay to energize. This relay also starts the fuel pump. Also make sure all connections ... more »

Make sure the tire is good and warm when installing. In the summer, set it out in the hot sun all day prior to the install. In the winter use a confined space with a lot of heat to warm the tire. Paw Paw
