What else can I help you with?
Is a 1998 Saturn SL2 a returnless fuel system and does it have a fuel pump regulator?
Yes it is returnless and the pump regulator is integrated into the fuel filter.
Where is the fuel pump relay located on a 1999 ford mustang gt?
The fuel pump relay on a 1999 Ford Mustang GT has a returnless fuel system which uses a Fuel Pump Driver Module. It is located underneath the luggage compartment trim panel.
Is there a fuel pressure relief valve on a 1999 Mazda miata?
The 1999 Mazda Miata is a returnless fuel system. It has a Fuel Pressure Regulator in the tank (above the fuel pump), and a snub at the end of the fuel rail.
What would cause an inline fuel pump to run continuously in a Mazda Navajo?
If it is fuel injected, the pump has to run continuously. If it has a carburetor, it is probably getting weak.
Do electric fuel pumps have an automatic pressure?
Some do. I'm about 90% sure your car does not. The part that controls the fuel pressure is called a fuel pressure regulator. Most are located near the engine, but some import and Chrysler's have a 'returnless' system, where the regulator is built into the fuel pump module assembly, in the gas tank.
What is the fuel pressure for a 2001 Lincoln ls?
Between 30 and 65 psi. The computer on the car determins the fuel pressure based upon need. There is a FRP (fuel rail pressure) sensor on this returnless system. The FRP sensor is a passive sensor and varies the signal return voltage to the computer which, inturn, controls fuel pump speed to vary the system pressure
What makes fuel pump run all the time on a 91 s10?
On a 1991 S10, a fuel pump that runs continuously could be caused by a faulty fuel pump relay, a malfunctioning ignition switch, or a short circuit in the wiring. Additionally, if the fuel pressure regulator is stuck open or there is a problem with the fuel injection system, it may also cause the pump to operate continuously. Checking these components and connections can help diagnose the issue.
Why would a fuel pump on a 1992 Chevy truck run continuously?
You might try the fuel pump relay.
Why would the fuel pump on a 1992 Aerostar run continuously?
As long as the engine is running, the fuel pump is running.
Why does the fuel pump run continuously on a 1991 suburban when ignition is turned off?
Need to replace fuel pump relay.
How does a return less fuel system work?
A returnless fuel system operates by delivering fuel directly from the fuel pump to the engine's fuel injectors without routing excess fuel back to the tank. This system typically uses a pressure regulator located at the fuel rail to maintain optimal fuel pressure, ensuring the injectors receive the correct amount of fuel for efficient combustion. The elimination of a return line reduces complexity, weight, and the potential for vapor lock, enhancing overall performance and efficiency in modern vehicles.
How do I make the fuel pump run continuously on a 1991 Lincoln Continental to empty the tank?
Start with an almost empty tank, (if possible), as running the fuel pump continuously for an extended period of time may overheat and damage the pump. Otherwise follow these instructions, and give the pump a "rest" every few minutes. Disconnect the fuel line anywhere before the fuel regulator, (e.g., @ the fuel filter), turn ignition switch to "on" (not start), and this will allow the pump to run continuously
