It is just me doing the work and I would love anyones thoughts or suggestions before I try and figure out how to drop the gas tank to change the darn thing, plus they are pretty expensive! I really think its the valve on the pump. I am sorry that the last message was incomplete. There is a fuel pressure regulator on the pump. Is one better than the other? I'll just tell you that after doing everything under the sun possible with the entire fuel system, the plugs, wires, fuses, relays etc etc etc, I could still not get it to start. They seem to last around 250,000kms and then give up.

Mark the terminals if necessary so that you remember which terminal has power. Bench tested it at home and zero power. However, there is a Power Steering Pump Reservoir above the Ignition Coil in the minivan which is not shown in your diagram. If not then the pump and filter is the problem. Went to bed feeling defeated.

It's made of metal and has two lines entering it near the top. Came home one night in Nov. To identify an individual injector that may be leaking, you might need to remove all of them for professional testing and cleaning: Ultrasonic cleaning may or may not fix the problem and the money better spent on injector replacement. It will spray 10 onces at best. This includes the purge valve, line, and canister. With the key on, there should be two terminals that have power.

Troubleshooting a Bad Fuel Pump in a Dodge

If after about 30 minutes, it is started again, it runs for another 15 minutes and then stops and so on. Furthermore, if there was a test port, I wonder why the original Daimler Chrysler manual has not said a word about it. They make fuel pumps for Carquest and Napa,they will not cover a defective fuel pump 99. Then that glorious day that a tech came and did just what i told him. I do not want to break it. The one way valve should confirm pump or injectors! Check your fuel pump, and fuel lines.

The design was as bad as the design of the fuel tank and filter where I had to remove the tank to replace the fuel filter which could have been, quite easily, kept in the engine compartment as was the case with other vehicles that I have owned. Turn the key off and look under the hood on the fuel rail for the test port with a valve stem cap, remove cap and using a rag and small screwdriver cover the screwdriver while mashing down on the valve stem inside test port.

Kabeer Sayeed Thanks for your response. Connect a suitable fuel pressure gauge between fuel supply hose and engine fuel line assembly. I discovered that the fuel shut-off switch located in the trunk and attached to the left rear fender was loosing connection. Below are also removal instructions for your fuel pump. It turns over just fine but will not start. This indicates that the fuel pump turned on and the pressure did reach specifications. People keep telling me it is the fuel pump, but then why did it start up when I put that new relay in it? Now start the engine and let it stall.
