Unknown Tune
I have a 2000 F350 i purchased that already has a tune on it but no one knows what the tune is or where the tuner is. I have a friend who can flash it back to stock. But his computer or my tire size programmer can see the key to on position and do not start. is there a fuse or relay that can cause this? The truck runs and starts fine. Any help would be greatly appreciated.

What exactly are you saying/asking here?
If it was flashed with a plug-in-play flash tuner, you probably will not be able to read the tune. I would say your best bet would be to flash back to stock so you know where you stand. If you are planning to install a chip, it will override any tune flashed on the PCM. If your friend is willing to flash to stock, I would do that regardless, that way you know where you are starting from.

Yeah that’s exactly what I want to do but none othe programmers are able to see the key on run position that is where my problem is that’s why I wanted to know if there might be a fuse or relay that might be bad,

The programmer powers up and can read codes it can get to the point of turn ignition off which I do and then when it says turn ignition on but that’s where the issue starts it doesn’t see the key on run position

If the "programmer" won't cycle during the event its most probably not comparable with the current Tune, coorupt data stream, or similar. Or, require uninterrupted Power during the process.
If he's attempting to re-flash the PCM to "OEM Programming" the file may be corrupt.

Not addressing your question, but here's something to think about if you flash the PCM back to stock. If your truck has injectors that need a custom tune in order to run, you'll be cutting your left arm off if you flash the PCM back to stock.

If you were to get set up to read the OBDII gauges and log the data, you could upload the log here and we could determine what injectors are in there.
OBDII tools link in my signature and a search for PID 3D in the thread title - that will give you a lot of info.
