Man, so frustrating to have a motor work fine for a day or two and then just quit running after starting or not starting at all??? The last few weeks I may go out and run several times, then get ready to move again or come in and nothing??? Turns over, just won't start, fuel pressure good, O2 Sensor just cleaned, vent hose to gas cap is clear, bulb fine and no leaks in line, (again, runs fine everyday and starts immediately like it always has)? It might be something simple, but I'm at wits end??? Thanks for all you mechanical people do, and I admire anyone who can work on motors of any sort!!
