Been running perfectly with no hint of a problem until I pulled into the oaoding bay at Home Depot. LOaded up, turned the key to re-start and the motor spins but doesn't fire off or even TRY to fire. No new fuel recently, plenty in tank, filter has about 750 miles on it. Jumper wire to FSS makes it click, but doesn't help. Pump was rebuilt a couple thousand miles ago. What next?
