So installed the Walbro today. Everything fit and went well. Fired right up after cycling the pump a few times. Road tested about 30 minutes and ran great. Stopped to fill up the tank; nothing unusual, always 1 click and done, leave cap off a couple of minutes and she fired right up again and I drove home. Parked it temporarily in the garage (hot and humid) for a couple of hours. Went out to move it into a corner of my garage so as to fit my daily driver next to it. Fired up, but I was giving it minimal gas so as to be careful near a wall and stalled it in reverse. Would not restart. Pump sounds fine, I cycled it a couple of times and the engine would not start, just kept turning over. Battery is new and tended. I let it sit another hour, popped off the tank cap for a couple of minutes, checked all the hose connections and all good, no leaks. Even hit the reset button behind the tank just in case. Still just kept turning over, can hear fuel pump with turning the ignition. Any thoughts before pulling the whole pump out?
