Fuel pump is not comming on there is no power to to pump is ther something that controles the fuel pump

wright you have changed the supply fuel system have you checked for a fuel filter or is the fuel getting to the engine if the filter is clean and fuel is getting through then ther is no fuel issue

re spark ie plugs / points / distributor or cap if not electro / leads / coils

ther is a wing inside the duct works usualy controled by a cable make sure it is hooked up

What year and model is it? I have seen this problem many times on the older Caravans. The fuel pump goes in at an angle and the bottom of the fuel pumps where the pick up is breaks off and will not get fuel at a 1/4 tank.
Hope this helps. Good luck.

If you are not getting fuel to injectors, and you have a new fuel pump that is getting power and you can hear it run for a few seconds with the key on - engine off, then you most likely have either a plugged fuel filter or faulty fuel pressure regulator.

You can go to autozone, com and register for a free account. Then login, choose vehicle year, make, model, engine size. Lastly, click on view repair manual. Now you have a free repair manual for your car.

If you do not have power to the pump, check that the safety switch for the fuel pump didn't go off. Should be down my passenger or driver kick panel.

A voltmeter measures voltage, so if your meter says there's no voltage, there's no power in the circuit at that point. Check your fuel pump fuse and electrical connection at the pump.

may be the fuel pump check for power going to the fuel pump if there is power then listen for the pump to come on when you turn the key to the on possition this will be a humming sound comming from the rear of the car

relay

HI. IF THER WAS A SHUT OFF THE MANUAL WOULD TELL YOU.I WOULD START BY LOOKING FOR A FUSE AND THEN THE FUEL RELAY OR A BAD WIRE AND I WOULD DO IT IN THAT ORDER. JIMBO

check to see if there is power to the pump. If there is then the pump is bad which is a common problem

Look for a bad fuse or relay. If both check out, most likely an ECM problem
