Sort of. There should be a relay that provides power to the pump when you first turn the key on. Then once the engine starts power is provided by way of the oil pressure switch. That way the pump won't run in an accident. The oil pressure switch grounds the fuel pump relay on some models.
the fuel sending unit is attached to the fuelpump, so the only way to fix it is replace the fuel pump assembly, sometimes they will make an aftermarket sender, you might want to check first.. but anyhow you can either replace it, or just keep track of your miles. hope this helps
This is a fuel sending unit code and it directly
related to you goofy gas gauge. This is a common problem in 2nd Gen
Isuzus. The fuel sending unit needs to be replaced. Most places will
tell you that you must replace the entire fuel pump assembly module but
you can buy just the sending unit.
Other faults to refer this problem and other codes: P0141, P0300, P0404, P1404, P1627, with this synthoms: hesitates sometimes on takeoff, gas gauge gives random
readings(sometimes will read empty, or full, or somewhere in between),
Fuel light flashes sometimes.
Your sending unit inside the gas tank must be going bad. Have this professionally diagnosed and if it needs replacement use your highest judgment screening for a repair shop to do it. This is inside the fuel tank and a 99% things can go wrong left to someone unfamiliar with working this critical.
The fuel level sending unit is located inside the fuel tank along with the fuel pump and will need to be replaced if it has burned out. It may be included with a new fuel pump assembly or sold seperately. There could be a bad electrical connection so be sure and check that all electrical connections are clean and secured before you spend money replacing parts and removing the fuel tank.
