Hi! Welcome to JustAnswer. Thank you for contacting us for assistance with your vehicle. I'm Ron. I will be happy to assist you with your question. May I ask to whom I have the pleasure of speaking with today?

My name is, Melissa. Hello, Ron. And thank you.

Hello Melissa. Nice to see you today! I'm sorry to hear you are having this problem. I know this can be frustrating. Please give me one moment to type out some information for you. Sit tight one minute. I'll be right back !

The fuel pump is controlled by the fuel pump relay and the relay needs power to it from the fuse #23 (20 AMP) located in the underhood fuse panel to pin #3 at the relay as well as power from the PCM relay at pin #1. The place to start here is to very the fuse is in fact in place and has power in and out of it and if that checks okay, move to the relay and check for power at the relay on pins #1 and #3. If the relay shows power at both pins then it needs a ground from the PCM (computer) on pin #5 to energize and send power out to the fuel pump from the relay on pin #5. See the circuit wiring diagram for testing reference in the link below. See the fuel pump circuit in this link.

Ok. The fuse checks out good. And the relay we didn't check with a volt meter. But, it clicks when the key is turned.

Okay if it clicking thane that usually means it intergizing, so move to the inertia switch and check to see if you have battery voltage into the switch on the Dark/green wire and out of the switch to the pump on the pink/black wire while cranking the [engine](/topics-engine-ford/) over. Both wires should read battery voltage while cranking the engine over and of so then you should have battery voltage at the fuel pump connector on the same pink/black wire.

Ok. We're not where the truck is at the moment. But, we will be within an hour. So, I will get back to you, then. Do I have to unmount the inertia switch, to test it?

No, you can leave it plugged in and mounted and simply back probe the connector at the switch while cranking the engine over.

Ok. Thank you. I will let you know the results.

You're very welcome, Melissa, Glad I could be of some help today! I hope everything works out well for you! If there are any additional questions on this issue that should arise, please feel free to reply and ask! Have a great day and Im here if needed!

You have a great day, as well.����

Thank you and Merry Christmas as well!

Ron. Get this. My boyfriend gets in the truck and proceeds to check the switch. When he pulled back the carpet covering the bottom of the unit, he noticed the connector was not pushed in all the way. He pushed it in until it clicked. Now the fuel pump kicks on when the key is turned. And, I just started it. YAY!!! Thank you, \*\*\*\*\* \*\*\*\*\* help. I'm so glad I subscribed. Otherwise, my boyfriend wanted to bypass everything and wire the fuel pump, direct.�� Merry Christmas!!!

Great, so glad to hear all is well, Glad I was able to help you with this as well, and thank you. Have a very merry Christmas as well.
