No throttle no codes
I have a 2005 f350. Yesterday I was driving to the store. On the way I was slowing down for a red light then the light turned green and I went to give the truck throttle and nothing happened. Throttle all the way to the floor with no response. Pulled over turned the truck off and tried restarting and didnt want to start again. Set there for a minute tried starting again cranked right up no problem. I drove to the store and when I stopped in the parking spot truck rpm dropped to about 500-600 rough idle no throttle response again. I went in to the store came back out and check codes on my scan tool. Showed no codes. Started to the truck and it cranked right up. Drove to get fuel and filled the truck up and it’s been running fine ever since. I drove around the neighborhood for about 30 minutes with no issues. Any idea what could cause this?

What scan tool do you have?
Do you have a fuel pressure gauge (if not, you need one)?
What was your fuel tank level when you had the issues?
It could be a number of things and you are going to need information to narrow it down. Hopefully you can monitor engine parameters.

My fuel level was low. Less than a quarter of a tank. I have a sct x4 I use for monitoring and checking codes. And I do not have a fuel pressure guage but will put that on the to get list.
Drove the truck about 100 miles today with no issues what so ever.

Well Im thinking/hoping it may have been just been a low fuel issue. Ive been driving the truck for a couple days with no issues at all. The driveway at my house has a fairly decent grade and I park it facing up hill. When I left to go to the store the truck showed a quarter of a tank but now I'm thinking that was false and the truck was about empty due to being parked on a uphill slope and all the fuel going to the rear of the tank. Question is would low fuel cause fuel pressure to drop which in turn cause a dead throttle?

I dont know if the part is the same, but we have a 2001 f250 7.3 at work that does this occasionally.
The accelerator position sensor is failing, and it has been getting progressively worse.

Have you checked the fuel tank pick up tube yet? That is the first thing to do IMO.
It is the red plastic piece in the pic that falls out and causes you to lose suction w/ 1/4 tank level.
