Question about Dodge Dakota

1 Answer

I have a 1995 Dodge Dakota. my problem seems to be with the fuel pump, or presure reg. As long as I keep at least 1/2 tank of fuel, it runs fine. But the more below 1/2 tank the more it starts to act like it's running out of fuel. I now have the pump out, and was looking for a view of the assy. I am wondering about a hose comming out 0f the top part of the actual filter. it only runs up about 5in.. That seems to be about 1/2 tank. do you suppose it is sucking air? If not what do you suggest?

Make sure you are with the tank half full, could be an error in the signal indicator of fuel, which would indicate a half tank when it might be less (or empty), with the option that the air entering system.

Keep in mind this information about the fuel injection system, so this is under a constant pressure. Before servicing any part of the fuel injection system, the system pressure must be released. Use a clean shop towel to catch any fuel spray and take precautions to avoid the risk of fire.
The MFI system uses an electric fuel pump mounted in the fuel tank. The fuel pump used in this system is a positive displacement, roller vane immersible pump with a permanent magnet electric motor.

For 1993-96 5.9L and 1994-96 3.9L/5.2L/8.0L models, as well as 1996 2.5L models with the "returnless'' fuel injection system, the fuel pump is referred to as the "fuel pump module''. For the returnless system, the fuel is drawn in through an opening tube in the bottom of a filter/regulator. The regulator portion is calibrated to maintain a fuel pressure of approximately 35-45 psi (241-310 kPa). The internal fuel filter is built into the assembly. The filter/regulator contains a diaphragm, calibrated springs and a fuel return valve. An internal check valve maintains some fuel pressure when the engine is not running to enable a satisfactory start-up. The internal diaphragm routes fuel in excess of 45 psi (310 kPa) back to the fuel tank. With this system, proper fuel pressure is controlled at the source, so there is no need for a separate return line from the engine to the tank as found in conventional fuel systems.

I suggest test following the next procedure... the fuel system test port is located on the fuel rail in the engine bay.

Fig. 3: A common fuel pressure test using a screw-ingauge rated to at least 60 psi (414 kPa)


1993-96 5.9L, 1994-96 3.9L/5.2L/8.0L and 1996 2.5L Models
see Figures 1, 2 and 3 (above)
With the engine at idle, the system fuel pressure should be within 35-45 psi (241-310 kPa).

  1. Uncap the pressure test port and screw in a fuel pressure gauge designed to read 0-60 psi (0-414 kPa), such as from set No. 5069. On the 8.0L engine, the test port is found at the front of the engine.
  2. Read the gauge. If within specifications, it will show 35-45 psi (241-310 kPa).
  3. If the pressure is 0 psi/kPa, you will need more extensive diagnosis using a DRBII or equivalent scan tool, and the appropriate Powertrain Diagnostics Procedures service manual. If the pressure is above 45 psi (310 kPa), the fuel pump is okay. Replace the fuel filter/fuel pressure regulator assembly.

Hope help with this.

2004 150 new fuel pump, enigine starts but dies, wait 5 mins. starts dies, unhooked fuel line very little gas


check the fuel presure reg but first check fuel ammount place fuel line un hooked in 1 galon glass jar turn ignition to run position container should fill quickly mesure fuel amount from single cycle call dealer ask what flow amount should be with single purge cycle
this will tell you if pump or filter are problem it will allow you to see if fuel filter is pooched and **** is bypassing also or if it is pluged

if results proper or close to dealer spec check fuel rail for bad fuel presure regualor if reg bad there will be little or no fuel presure even during purge cycle if flow high and finger cant hold presure if is usually fine and reg is bad pick up new reg from salvage it will cost 5 - 20 bucks and if a likely culprit

I have a 1995 dodge dakota v6 sport truck that starts skipping when it gets to a half or a quarter tank of gas?


Hi There. Let's see if we can help. If truck runs normally after filling the tank, next time it acts up and you add fuel, record how much fuel you added. You then need to determine how many gallons your tank holds. A quick phone call to your local Dodge dealers parts dept with the VIN number will usually get you that info. Next, refering back to your notes, if you have a 20 gallon tank, it acted up at 1/4 full, then you should have added approx 15 gallons! This simple test verifies that the fuel gauge is reporting fuel level correctly. If it is, then there is most probably an issue with the fuel pick-up tube or fuel pump strainer in the tank not extending to the bottom of the tank. Inspect the exterior bottom of the tank. Are there indications of damage to outside bottom of tank? Is it pushed up or deformed? Fuel tanks, especially on pickups, are prone to damage from running over something. If no visible damage is apparent, have you had the fuel pump replaced or did the problem arise after the fuel pump assembly was replaced?. Summary: If fuel gauge reads right and no visible damage to tank is apparent, then the tank needs to come down for removal and inspection of the fuel pump module. Good Luck!

1995 dodge van falls down when the fuel tank gets to 1/4 of fuel


sounds like a possible pluged fuel filter or a tired fuel pump. the pump is cooled by the gas. so if you work it at 1/4 tank or below it tends to get hot. but towing may make it hot anyway. check fuel pressure and the replace the fuel filter
