Customer Question
Hi, on cold mornings...

Hi, on cold mornings when I start my 2006 f-150 lariat, the radio, windows and gauges don’t work. When the truck warms up they come back on with a check engine light. I pulled the code and it is a fuel level sensor. I suspect it is the delayed accessory relay as all those parts are governed by it. Would cold weather effect it though?

Mechanic's Assistant: Does the light stay on, or does it blink?

Stays on

Mechanic's Assistant: Are you fixing your F150 yourself? What have you tried so far?

I’d like to fix it myself as I have little money and Xmas is round the corner! I just pulled the code.

Mechanic's Assistant: Anything else you want the mechanic to know before I connect you?

Just correlation with cold mornings and it remedying itself as the truck warms.

G​ood morning, I hope you are doing great. My name is***** am a Ford technician and I would be happy to help you out with this.

​Based off what you have described I as wwll am leaning towards an issue with the accessory delay circuit. It is one of the only things that all these items have in common. It absolutely could be affected by the cold, sometimes the relays will get weak, and if it is cold it may not have enough juice to fully close the relay contacts. I would recommend swapping that and re-testing the system

AlvinC answered a question about my Ford truck that only someone with an in-depth knowledge of his subject would have known what was going on.

Rich DUSA

Because of your expertise, you armed me with enough ammunition to win the battle with the dealer. They are installing a fuel filter and fuel pump at no charge to me.

I do know, after going though this with JustAnswer, that I can somewhat trust my mechanic but I will always contact you prior to going there.

BRNew Jersey
