Engine Mechanical problem
1996 Dodge Caravan 6 cyl All Wheel Drive Automatic 102117 miles

i am looking for a diagram on the fuel pump. Anything I can find would be a big help. Our van will not start even with a jump. It sounds like there is no fuel getting to the engine. Could it be something besides the fuel pump?

Thanks for the donation

To better assist you, could you please list the 8th digit of your VIN and your engine size i.E. 3.0L, 3.3L etc.

It could be several things other than the fuel pump. You will need to test pressure at the fuel rail to see if you have proper pressure or any at all. If you do have proper fuel pressure, you will need to test spark at the plugs and wires.

Great, thanks for that info.

Below is a pressure test of your fuel system. Post the results of the test and I will follow up. Below are also removal instructions for your fuel pump. If you need further assistance, just let me know.





Release fuel system pressure.
Disconnect the fuel supply hose from the engine fuel line assembly. Connect a suitable fuel pressure gauge between fuel supply hose and engine fuel line assembly.
Using the DRB II tester, or equivalent, with the key in the RUN position, use "Actuate Outputs Test-Auto Shutdown Relay'' this will activate the fuel pump for 1.5 seconds to pressurize the system.
If the gauge reads 46-50 psi (317-345 kPa) fuel pressure is correct and no further testing is necessary. Remove all test equipment.
If pressure is not correct, record the pressure and continue with the test procedure.
If the fuel pressure is below specifications, install the fuel pressure gauge in the fuel supply line, between the fuel tank and fuel filter at the rear of the vehicle.
Repeat the test. If pressure is 5 psi (34 kPa) higher than recorded pressure replace the fuel filter. If no change in pressure is observed, gently squeeze the return hose. If the pressure increases replace the pressure regulator. If no change is observed check for a defective fuel pump or plugged filter sock.
The test (Step 8 ) should be performed when fuel tank is at least 1/2-3/4 full.

If the fuel pressure is above specifications, remove the fuel return line hose from the chassis line at fuel tank and connect a 3 ft. (91cm) piece of fuel hose to the return line. Position the other end in suitable container (2 gallons/7.5 liters or more). Repeat test and, if pressure is now correct, check in-tank return hose for kinking.
Replace the fuel tank assembly if the in-tank reservoir check valve or the aspirator jet is blocked.
If the pressure is still above specifications, remove fuel return hose from fuel pressure regulator. Connect a suitable hose to the fuel return line and place the other end in a suitable container. Repeat the test. If the pressure is now correct, check for restricted fuel line. If no change has occurred, replace the fuel pressure regulator.
