Pontiac Fiero Fuel Pump
The Pontiac Fiero Fuel Pump is essential when it comes to the supply of fuel to the engine as well as determination of combustion. It conveys fuel from the tank to the carburetor or the fuel injection system and mostly uses electric pumps in the fuel injection. Fuel is pumped mechanically with the aid of the cam shaft to the carburetors. Performance fuel pumps are flow rated in GPH or LPH Depending on the horsepower that is required. While having mechanical pumps mounted on the engine has been financially conventional, PEX pumps are more powerful and preferable since the modern designs use PWM for longer pump life and energy consumption. In conclusion, the Pontiac Fiero Fuel Pump plays a critical role of ensuring that the engine receives the required fuel amount and pressure for efficiency.

Pontiac Fiero Fuel Pump Parts Questions & Experts Answers
- Q: What is the location and function of the fuel pump on Pontiac Fiero?A:The fuel pump is located in the fuel tank for both four-cylinder and V6 models and is non-repairable. When the key is turned on, the ECM activates the fuel pump relay for quick pressure buildup. If not started, the ECM waits for engine start, using the oil pressure switch as a backup if the relay fails. A malfunctioning relay may cause long cranking times. The ECM powers the fuel pump when ignition is on, relying on HEI distributor pulses. To test the pump, install a fuel pressure gauge and turn ignition on. If no pressure, check the fuse and wiring. For a good fuse but no pressure, test the pump by applying battery voltage. Inspect the system for pressure discrepancies, leaks, and faulty components, including the relay and connector.
- Q: How to remove the fuel pump/sending unit assembly on Pontiac Fiero?A:To remove the fuel pump/sending unit assembly, start by disconnecting the cable from the negative battery terminal. Then, relieve the fuel pressure. Next, remove the Fuel Tank. Inside the fuel tank, the fuel pump/sending unit assembly is held in place by a lockring mechanism. To unlock it, turn the inner ring clockwise until the locking cams are free of the retaining tangs. If the rings are too tight, gently knock them loose with a soft-face hammer. Carefully extract the fuel pump/sending unit assembly from the fuel tank, making sure not to bump it into the outer lockring. Inspect the condition of the rubber gasket and replace it if necessary. Also, inspect and clean the strainer on the lower end of the fuel pump. If needed, separate the fuel pump from the sending unit by pulling the pump assembly into the rubber connector and sliding it away from the bottom support. Take care not to damage the rubber insulator and fuel strainer. For installation, insert the fuel pump/sending unit assembly back into the fuel tank and turn the inner lockring counterclockwise until the locking cams are fully engaged by the retaining tangs. Finally, reinstall the fuel tank.
