Hello to all, I have just become a new member of the F150 owners and I have already started to mod up the 5.4. I have a 2004 F150 Lariat package, and I just purchased the Edge Evolution yesterday at 4 Wheel Parts here in Austin. I installed it exactly how the directions said, and it was very easy by the way, anyways when I plug it in with the key in the on position I get no display or nothing. I tried wiggling the cable around and still nothing, unplugged and and replugged it and still nothing. Then I went to the computer and updated it and that worked, the backlight came on when it was finished programming, so I know the module works, but what I want to know is, has anyone else out there had this problem and if so what did you do to fix it? Thanks for any info possible.

 

The fuse for the OBD port and the cig lighter are the same. Do you have power to the cig lighter??? That is the first thing to check. The fuse box is behind the kick panel on the passenger side.

 

Hey Ftruck05, thanks for the quick reply to my post, you hit it right on the nose. It was the fuse. I picked up a .50 cent fuse from Walmart and BAM I was in business. Thanks again.

 

I'm glad you got it workin' and all, but wouldn't it have been easier to just look in the user manual?

From page 43 - Troubleshooting:

"• NO DISPLAY WITH KEY ON – If you should get no display when turning the key on, check all of your fuses and make sure your battery is fully charged. Disconnect and reconnect the OBD-II cable to ensure the Evolution restarts properly. If the unit restarts but fails to stay on, or fails to turn on when the key is on, there is most likely a communications issue. Contact Edge Products Technical Support for further assistance."

RTFM

 

I did, but I did not think that a fuse would have been the problem seeing as how I just bought the truck two weeks ago. Plus I was looking for my manual on the truck to see where the fuse was. They are not labeled on the fuse box. Anyhow I appreciate your concern.

 

No problem man. Glad to help
