When you crimp the fuel return line, it creates a restriction in the fuel flow, which can lead to increased fuel pressure in the fuel rail. This higher pressure can temporarily allow the engine to rev up because more fuel is available for combustion. However, this is not a sustainable solution, as it can cause fuel starvation and damage the fuel system or engine due to excessive pressure over time. It's crucial to address the underlying issue rather than relying on crimping the return line.
A lack of fuel. Can cause your vehicle not to idle. A dirty fuel filter can cause the same problem. The fuel injection pump can also cause your vehicle to not idle properly.
A bad fuel pressure regulator or a clog in the fuel return line that leads back to the tank will cause this.
follow your fuel lines and find filter hold the fuel lines make sure to not break or crimp line and use a wrench to remove filter make sure there is no flames anywhere near cause there is gas in the filter
Yes, it can very well cause the vehicle start missing and run rough because it is starving for fuel. Replace the fuel filter and see if this solves the problem. It very well may be that your fuel pump is failing.
Yes; if your fuel pump relay fails you will not get fuel to your motor and your vehicle will not start.
Get a fuel pressure test gauge making sure you get one that can handle your pressure. Hook it all up. Run engine. Then as soon as you turn off engine, crimp off fuel return line to gastank. If pressure drops you've got a stuck open injector or other leaks.
Replace the fuel filter, and check for a crimp in the line somewhere. Also look at the fuel pressure regulator.
There is a pressure regulator on the fuel rail, it regulates the fuel pressure to about 45 lbs/sq.in. Excess gasoline is sent back to the fuel tank via that return line. If the return line is somehow blocked or plugged up then the excess fuel might cause flooding thus the engine would die. I assume that when you loosen the return line it leaks fuel out?
Bad fuel pump will cause the engine to stall or not start at all. A bad automatic transmission will cause the vehicle to jerk and not run smoothly.
If the fuel is making it through the fuel filter but not to the fuel rail then I would check for problems in the fuel line, such as a clog or crimp in the metal line or perhaps a problem in a flexible line.
Depends on the vehicle, on most every fuel injected vehicle the answer is yes.Depends on the vehicle, on most every fuel injected vehicle the answer is yes.
To replace the fuel return valves on an 1985 Jaguar XJ6, first ensure the vehicle is off and the fuel system is depressurized. Remove any necessary covers to access the fuel rail, then disconnect the fuel lines from the return valves. Unscrew and replace the old valves with new ones, ensuring they are properly seated and sealed. Reconnect the fuel lines, check for leaks, and start the engine to ensure proper operation.
