Hard starting, stalling, sputtering or a gas gauge that reads wrong can mean the pump or float is worn, and other parts in the fuel and electrical system produce some of these signs too. With the key off, look over the fuse, relay and wiring connector for damage before you order; fuel pressure tests are a shop job.
