What to do if my Winco Portable Generator engine cranks but will not start?
If your Winco Portable Generator's engine cranks but won't start, several factors could be at play. First, ensure the fuel supply is turned on and that the fuel tank isn't empty; refill it if needed. Improper fuel delivery could also be the culprit, so check the fuel delivery system. Other potential issues include air in the fuel system, which requires bleeding, a fuel solenoid that hasn't opened (check its operation), or a defective fuel pump or fuel solenoid, both of which should be tested and replaced if necessary. Also, verify the engine harness for defects and check the battery voltage to the fuel pump or fuel solenoid. Addressing these points should help diagnose why the engine cranks but fails to start.
