It is possible that your fuel pump may be failing. Sometimes you can prime the fuel pump by turning the ignition from off to on a few times. This will allow more fuel to be primed into the engine. This may have been why you were able to make it home. I would recommend having your fuel pressure tested and compared against the manufacturer’s specifications. If the fuel pressure is low, you may have a dead fuel pump, clogged fuel filter, or faulty fuel pressure regulator. Consider YourMechanic for this inspection as it can be completed at your home or office.
