No start situation
1984 F250 4x4 Aspirated 6.9 liter
I'll start by saying the glow plug system on her had been re-wired into a manual hold-in type switch. I have since replaced all glowplugs due to the fact that the P.O. fired the truck with ether and burnt them up.(even the day he sold it to me without telling me. he let me believe it was easy to start.) I had to fish out small pieces from #2 and #7 with a magnet and a hook.
Injection pump is new.
Starter is new.
Batteries are good.
Fuel is all new and in a cleaned tank.
Test light indicates power to the glow plugs.
I still cannot get her to fire up even when it is 80 degrees outside?!?
The truck will start with ether as I stated above and it will fire right up after she has been driven a while as well, but basically no 1st start of the day or after sitting more than 3 hours without help so it has sat for about a month as I don't want to ruin it with the ether.
Help/Suggestions? Anyone know anyone or trust anyone locally in the 50315 area (Des Moines, Iowa)

Mine kinda does the same thing...
I know I have multiple air leaks on return lines and found a P.O. rigged up fuel line to the front tank...
all of which will be getting fixed after the tranny rebuild

If you have a working block heater, you should be able to plug it in for a few hours and it should start. If it does, it points towards the glow plugs as the possible problem.
If it still doesn't start, I would suspect air intrusion from leaking return lines.

If it will stay running then it is not a fuel prob and he said it fires even if it sat for over an hour. After three hours the block will have cooled down to nearly ambient so... It is more than likely a GP problem. It would start then die repeatedly till it bled itself of air and run on fuel rather than just firing right up. But just for fun, go out and crank it over with the pedal held to the floor and see if it smokes out the tail pipe. If it does then you are getting fuel. If it does not then you arent getting fuel and it is an odd little problem. My opinion, GP's. Can you describe how it is wired and how much power you are putting to the individual plugs? Test light will be essential as well as a multimeter.

I have removed the scotch locks and replaced with crimp connectors and will be testing for specifics (to each gp) in the next couple of days and get some updated pictures. I have recently offered a 1988 Dodge colt wagon to anyone who can help me get this figured out and my neighbors son may be willing to help me out. It is just finding the time now..

Transmission fluid and filter changed. Custom exhaust almost done. I listened to each cylinder with the stethescope and heard no awful noises so I must have gotten all the shattered pieces of glow plug removed.
