Activation.
Make sure you have voltage at the pump. If you do then the new pump is defective. If not, the fuse is blown or the fuel pump relay is bad. Where is relay?
yes, the purpose of the relay is to signal the pump to turn on and off, if its not working at all the fuel pump will not turn on.
You should check the fuel pump fuse to make sure is not blown. If the fuse is good the fuel pump relay may be defective. It is always simpler to replace the fuse and the relay before removing the fuel pump.
If the fuel pump is bad it will just quit pumping gas, the electric fuel pump always makes a little noise when running.
A 2005 PT Cruiser does have a fuel pump relay. They have a fuel pump relay rather than a fuel pump switch. The fuel pump relay is located in the fuse box.
Normally the fuel pump relay is separate from the AC. You can pull and switch positions of identical relays, depending on what you are trying to accomplish. If the fuel pump relay is working, and the rest of that circuit is okay, you will hear the fuel pump come on with a little whirring noise when the key is turned on.
The main relay and the fuel pump relay are the same. Take the fuel pump relay and swap it with the main relay and see if that will help you....
Blown fuse, defective fuel pump relay, or defective fuel pump.
If the relay is bad, then the fuel pump will not work.
Yes, the fuel pump relay turns on and off sending power to the fuel pump as needed. The best to test that relay is to just replace it with a new one. Also make sure and check the fuel pump fuse and replace the fuel filter as it might be clogged.
Yes, it is a fuel pump relay.
WHEN RAISEING THE HOOD THEIR WILL BE A FUSE BOX ON THE LEFT FRONT FENDER AND IT WILL SAY, ON TOP OF THE BOX FUEL PUMP RELAY, REMOVE COVER BUT CHANCES ARE THIS IS NOT YOUR PROBLEM YOU SHOULD CHECK CHECK FUEL PRESSURE BEFORE YOU DO ANYTHING, TURN KEY ON AND LISTEN FOR HUMM FROM FUEL PUMP IF NO NOISE CHANCES ARE IT IS THE FUEL PUMP HOPE THIS HELPED!! IF YOU DO HAVE NOISE IT IS MORE THAN LIKELY THE FILTER STOPPED UP.
