WHERE DO YOU CHECK THE FUEL PRESSURE ON A 1991 DODGE STEALTH
I have a 1990 Mercedes 500sl and there is a suggested tire pressure sticker located on the inside of the fuel door.
where is the fuel pressure regulator on1991 lumina 3.1 /
Behind the rear seat.

A plugged up fuel filter, a faulty fuel pressure regulator or a faulty fuel pump.
Well on my 1991 Mercedes Benz 190e the fuel release door is automatic. All you have to do is make sure all the doors are unlocked with the master key and then, go to the fuel door and lightly press in on the left side of the fuel door and pull from the right and it should pop open.
Try replaceing the filter or the fuel pressure regulator.
Correct me if I am wrong but a fuel pump does not hold fuel pressure it maintains the fuel pressure needed for the vehicle to run. What holds the fuel pressure is the fuel injectors and believe it or not the fuel pressure not only regulates the fuel pressure but also holds it. If the regulator is bad your vehicle will not hold the pressure needed to run the fuel pulse dampener also plays a small roll in this question too
50 to 55 psi
at idle between 25-35 on acceleration it should get up to around 50psi. if it drops fuel pump is bad you can purchase one on eBay for around $80
A bad fuel pressure regulator or a clog in the fuel return line that leads back to the tank will cause this.
open your fuel filler cap door and Mercedes tire pressure recommendations are on a sticker on the fuel door. i personally go 2-4 more psi then recommended.
it should be around 4psi
Fuel filter, fuel pump, or pressure bypass/relief valve is not providing the correct, enough fuel pressure at the injectors.
Yes... The main fuel pump receives fuel under pressure from a primer pump located in the fuel tank.
65 pounds of feul pressure
The fuel pressure regulator on a 2002 S 430 Mercedes Benz is located in the fuel pump. This is a very important part of your car as it regulates the amount of fuel that your engine takes in.
