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!!

An engine needs 3 things to run. Fuel, Air and spark. You've checked the spark so move onto the air and fuel system. I'm assuming you did a full service on the replacement engine after you fitted it? Even a dirty Air filter can cause bigger issue that you would expect. Have you checked to see if the engine is getting Fuel? If it is just turning over and not trying it might not be getting fuel to the cylinders. When you checked the plugs for a spark were they wet and smell of fuel when you first took them out? Have you had the vehicle scanned with an OBD2 scanner for trouble codes? These can give clues to what and where the problem might be. If you have to pay for the scan get prices at 4 or 5 different places as prices can be VERY different.

TO REPLACE A DISTRIBUTOR FIRST YOU HAVE TO GET ENGINE IN NUMBER 1 FIRING POSITION IN COMPRESSION STROKE.WITH ROTOR POINTING TO NUMBER 1 POSITION ON DISTRIBUTOR CAP BESURE TO PUT NUMBER ALL PLUGS WIRES AND NUMBER ON DISTRIBUTOR SO YOU WONT GET CONFUSE AND MARK THE DISTRIBUTOR BASE ALSO SO YOU CAN PUT IT BACK IN THE ORIGINAL POSITION.

Question moved from Computers to Jeep Grand Cherokee There is so much under there, it is impossible to tell. The most likely is a connector getting warm, but it could be so many things, even the radio, or the resistor on the heater blower.

you should have a purple wire on the anitheft moduel ground it and it should disarm the alarm

lock and unlock the passenger door with the key, if the alram still sounds or u have a no start u will need to have the system scanned there is a problem with it.

Open the door panel cover and grease or lubricate the window lifting mechanism. Apply rubber grease to the rubber rails.

Check the battery, it sounds like it's flat. Try charging the battery to see if it recovers, but if the battery is about 3 years old or more it is likely to have failed and replacement is the only viable solution.

FUEL PRESSURE REGULATOR IS AN INTEGRAL PART OF THE FUEL PUMP MODULE CANT BE REPLACED SEPARATELY.

You meant the fuel pressure regulator? It is located on the fuel rail and has vacuum attached to it. This is not the problem with your car tho. Check the ignition module, and the ignition coil.

Sounds to me like you have bad universal joint bearings in a CV joint.

Hello and welcome to FixYa . Locate the dial that controls the brightness of the dashboardlights. If the control is not immediately evident. Make sure the brightness control is turned on. If it is and the lights aren't working, the problem may be a bad fuse. Check the fuse that controls the dashboard lights Replace the fuse if necessary. If just one part of the instrument panel is not lighting up, then you have either a burned-out bulb or a wiring problem.

This should get you going. And you can always Ask Me.

You might check your fuel filter and hoses..could also might need carberator adjustment?

Hi.

Check the hood ajar safety switch that is located under the hood at one side, near the front. The switch can be tested using a VOM set on impedance to check if it does close and open. The switch can also be tested jumping and opening its contacts.

Start opening the hood and locating the switch. See the diagram below:

If it has no bleed screw then you need to loosen the flange nut(that holds the pipe to the slave cylinder). Pump the pedal a couple times then hold it down. Loosen the nut till the fluid comes out. Fasten again. Pump and hold. Loosen etc.
