2000 Dodge Grand Caravan is getting no fuel to the fuel rail. The fuse is good and the relay also appears to be good. I don't hear the pump come on when turning on the ignition. Since the pump is in a full tank, I would like to know if there is anyway to make sure it is the pump?

The PCM /ECM won't energize the fuel pump relay while cranking the the engine ,unless it get's rpm signal from the crank sensor . Is there spark at the plug wires ?

Are you getting at least 12 volts to the harness on the pump and also is it grounded good? Have you checked the fuse for the fuel pump and the fuel pump relay? Is the ASD relay coming on when you turn the switch to run position? Several more things to check to solve your no start condition.

listen at your fuel tank to see if you can hear the fuel pump running
if it isn't check your fuses as well as your relay if these seem to be ok then it's probably the fuel pump

put a funnel in the gas nozzle have someone turn ignition on to almost start, but don't. You should hear pump running before you start your van if you don't hear the pump you know you have a defective pump if you hear the pump purchase a fuel filter try that if not possibly could the relay not sure where its at but could finds out for you.good luck

Hi:

I think you will find the FP relay under the hood in one of the two black power distribution boxes.

When you turn the ign key to run, you should hear the pump run for 3-5 seconds to prime the system, then stop. You might have someone lie down outside and see if they hear it.

Verify that relay and fuse for pump are good first, and then attaching a pressure gage to the fuel rail will confirm whether or not pump is working properly if at all.

Also, make sure that your battery is not the culprit before replacing the pump. Chrysler products are very sensitive to a flaky/dying battery.

The panel or the housing normally lists the names of the items that are controlled by the fuses. If that doesnt work, disconnect the battery terminals and you are good to go

hello i am trying to find where is the shut down relay loation on my 2000 caravan since it does not have the fuse box cover

possible bad fuel pump. check fuel pump relay under hood. drivers side fuse panel. swap fuel pump relay with another identical relay to rule out possible bad relay. listen for whining sound back by fuel tank. the fuel pump is in the fuel tank. Another option....you can also check the pressure in the fuel rail, but be careful not to squirt gas in your eyes or face.

Dear Ron, you have replaced fuel pump and fuel filter. You have checked the fuel pump relay. Still no fuel in rail. Try bypassing fuel relay with jumper from batt to fuel pump. If o/k then check computer for ground to relay. This system uses a relay that is operated by the computer that supplies a ground for the relay to operate. The wire color is green,16 gage. If the ground is not available then "no fuel" Check this with a test light. Key on and crank apply test light to ground wire and other end of light to ground. You should hear relay click and get fuel. If this checks out you will need to replace computer or get creative with rewiring the relay so it works without computer input. Good luck Moe

It would appear that the relay is located on the cross rail that runs across the front of the vehicle (in front of the radiator). I found out that it is riveted in place by a single rivet, so in order to replace mine, I will have to remove the rivet and use a self-tapping screw to secure a new one.
The fan relay is located in the fuse panel located under the hood beside the battery. It will be marked under the lid. Make sure you check the maxi fuse for the fan also.
