For the seat bottom, you just need to pull it up. The seat backs would have to be unbolted.

You probably disconnected the battery to install the new fuel pump. The alarm system will act in this manner after reconnecting the battery. Put the key in the door and lock the door. Then unlock the door. Try starting the vehicle now.

Hi,

Lets start with technical bulletin how to determine whether fuel pressure regulator is at fault or not :-

FUEL PUMP PRESSURE TEST - ALL ENGINES WITH PRESSURE TEST PORT

Use this test in conjunction with the Fuel Pump Capacity Test, Fuel Pressure Leak Down Test and Fuel Pump Amperage Test found elsewhere in this group.

Check Valve Operation: The electric fuel pump outlet contains a one-way check valve to prevent fuel flow back into the tank and to maintain fuel supply line pressure (engine warm) when pump is not operational. It is also used to keep the fuel supply line full of gasoline when pump is not operational. After the vehicle has cooled down, fuel pressure may drop to 0 psi (cold fluid contracts), but liquid gasoline will remain in fuel supply line between the check valve and fuel injectors. Fuel pressure that has dropped to 0 psi on a cooled down vehicle (engine off) is a normal condition. When the electric fuel pump is activated, fuel pressure should immediately (1 - 2 seconds) rise to specification.

All fuel systems are equipped with a fuel tank module mounted, combination fuel filter/fuel pressure regulator. The fuel pressure regulator is not controlled by engine vacuum.

WARNING: THE FUEL SYSTEM IS UNDER CONSTANT FUEL PRESSURE EVEN WITH THE ENGINE OFF. BEFORE DISCONNECTING FUEL LINE AT FUEL RAIL, THIS PRESSURE MUST BE RELEASED. REFER TO THE FUEL SYSTEM PRESSURE RELEASE PROCEDURE.

1. Remove protective cap at fuel rail test port. Connect the 0 - 414 kPa (0-60 psi) fuel pressure gauge (from gauge set 5069) to test port pressure fitting on fuel rail
2. Start and warm engine and note pressure gauge reading. Fuel pressure should be 339 kPa ± 34 kPa (49.2 psi ± 5 psi) at idle.
3. If engine runs, but pressure is below 44.2 psi, check for a kinked fuel supply line somewhere between fuel rail and fuel pump module. If line is not kinked, but specifications for either the Fuel Pump Capacity, Fuel Pump Amperage or Fuel Pressure Leak Down Tests were not met, replace fuel pump module assembly.
4. If operating pressure is above 54.2 psi, electric fuel pump is OK, but fuel pressure regulator is defective. Replace fuel filter/fuel pressure regulator. .
5. Install protective cap to fuel rail test port.

Now,

The fuel pressure regulator is part of the fuel pump, it is in the fuel tank.

On this vehicle the regulator is part of the pump and not serviceable separately so if the regulator is bad the whole pump assembly will need to be replaced.

Good Luck!!

Thanks!!

Good evening i have a 2011 grand Cherokee with a problem.everything works except for gas pump.when run volts direct to pump it works, but when the truck starts up by it self it wont.


I would look at three things: 1) fuel pump relay and 2)fuel pump regulator. It may have an electronic regulator that 'chops' the power to the pump to regulate pressure.
Third, there may be a sensor in the fuel line that reports pressure to the computer which it uses to regulate pressure. Apparently the pump is good, unless it is overdrawing current due to wear or bad brushes.
