Not starting, engine temp light on
I have an 84 6.9L F350 XLT. Its been sitting unused for 3 months. When I turn the key the glow plug light turns on for a few seconds then turns off but then every ten seconds or so it will turn on for another second; the light stops flashing after a minute or two. Then I crank it and the starter sounds fine but the engine temp light turns on the second I turn the key. I don't here the usual roar like the engine is engaging. I can't see any smoke coming out of the tailpipe.
A few things: I charged the batteries, the starter is only 6 months old, the engine is not hot.

No Smoke, No Fuel ...
Pull the Fuel Filter and fill it with clean diesel or something like Diesel Kleen through the outer small holes, not the large center one.
You might also want to check all the glow plugs ... See the Read first stickies at the top of this forum.
Why was it parked, was it running when it was?
How much fuel is in the tank?
-Enjoy

Thanks for the help.
It was running fine I just didn't use it for 3 months. The glow plugs are all good and the gas tank is half full. I put fresh fuel in the fuel filter, it was mostly empty. I'm told there is vapor coming out of the tailpipe but still no smoke and the tacometer isn't moving. I'm worried about the engine temp light coming on for seemingly no reason I can't find another post anywhere where someone had that happen.

The engine temp light has nothing to do with the starting problem.
In fact, the light coming on when cranking is normal; that's its self-test like many idiot lights in newer vehicles.
Keep on that fuel issue, you have air and plenty of it in your system.

Sounds like you need to bleed the fuel system, if the fuel filter was half full, that means you have s small air leak and the fuel is returning back to the tank. This is a common problem and affects nearly all the older trucks. There are 100's of posts on this issue. The truck probably will not start without bleeding the air out of the system

Lift pump
So I did need to bleed the system but that didn't help because the lift pump wasn't working. There was even fuel coming out of my bleeder valve but apparently it wasn't enough fuel to get the engine started.
