How to relieve fuel pressure

The procedure shown below for old model Chevrolet Corvette

Remove the fuel pump relay and crank the engine until the pressure is gone.

Another procedure is to place a rag over the schrader valve on the fuel rail and, with a small screwdriver, push the center of the valve and release the pressure there.

See the fuel pump components image below :-----

These details will help.

Thanks.

Cold start problem in car.Basically noticed when car stands overnight in cold weather.The starting problems in winter in cold mornings.
Basically its fuel pump problem on cold start.
One way to verify that this is the problem, in the morning when the engine is cold, turn the key to on, NOT START, just on. Leave it there for 3 seconds then turn it to off and then repeat this process 3 times.
Then try to start the vehicle.
If it starts right up, the problem is the fuel pump.
What is happening, overnight or when the vehicle sits for a period of time to cool down, the fuel is returning to the fuel tank. The fuel pump has a check valve in the pump that keeps the fuel in the fuel lines to the engine for easy starting.
When the check valve goes bad, all the fuel in the fuel lines drains back to the fuel tank. Then you have to crank, or cycle the key in the ignition to resupply the fuel lines to the engine.
The check valve is part of the fuel pump itself and is only available with the complete fuel pump assembly.

This details will help you.

Emergency fuel shut switch on Ford car?

It all basically depends on Ford car year model.This emergency shut of switch is actually called Inertia switch.
That said, most Ford models have the Inertia Switch [which controls power to the fuel pump] behind the kick panel on the passenger side. The kick panel is the plastic panel just above the outer edge of the carpet, directly in front of the front inner edge of the passenger side, front door.

Hope this helps you.Thanks.
