How to diagnose fuel injection problems on dodge 5.9


HII,
  1. Relieve the pressure in the fuel line before disconnecting it. To do so, you have to disable the electric fuel pump before you start the engine.To disable the fuel pump, do the following:
    1. With the engine off, remove the fuel pump fuse from the fuse box. (Your owner's manual should show you where it is.)
    2. Make sure that the parking brake is on and that the vehicle is in Park or Neutral, and then start the engine. It won't run very long after you start it up, but the pressure in the fuel lines will be reduced.
    3. Turn off the engine. With the fuel pump disabled, you're ready to disconnect the fuel lines from the filter.
  2. Look at the old filter and the new one before disconnecting anything.You should see an arrow stamped on both filters that shows in which direction the fuel flows through it. If the new one doesn't have an arrow on it, look to see in what direction the old filter is installed so that you can tell which end of the new filter goes where.
  3. Remove whatever is holding the old filter in place and remove it.
  4. Put the new filter on in the same position as the old filter.
  5. Replace whatever holds the filter in place, and make sure it's secure.
  6. Replace the fuse for the fuel pump in the fuse box. Make sure that the parking brake is on and that the vehicle is in Park or Neutral, and then start the engine and check for leaks around the filter.

Fuel pressure


Well most engines have a mechanical pump on the engine, but the E350 models used for motor homes and box vans also use an electric pump in the tank. The pressure rating is still 5-8 psi like the mechanical pumps.
Have you replaced the inline filter ?

My fuel pump on my 99 cougar v6 only runs for a half second then shuts off I've replaced the filter , the pressure regulator valve , the pump and it still does the same thing . could I have a ecm prob


Generally, the computer only runs the pump long enough to start the engine and build oil pressure. After that, the oil pressure switch keeps the pump on, most of the time by supplying a ground to the fuel pump relay. This is a built in safety thing, when the engine isn't running, the fuel pump shuts off. Most public libraries have Chilton's manuals, or you could pick up a Hayne's manual at a store like Autozone. These books can help you locate the relay and oil pressure switch, as well as provide wire colors for your specific vehicle.

Fuel Pump isnt running. will not start. Its not the collision reset. Simply no elec going to the pump at all. Ran fine yesterday.


Fuel Pump Relay can cause this, so can a bad ground or a dead pump. I would also check the fuse for the Fuel Pump.

Because the fuse is missing and hard to find I would look to see if someone by-passed the fuse and that be the problem. It should be fused.
