The flickering could be happening because your GP relay could be cycling and sucking all/whatever juice is available. If your batteries are low, that could bring the voltage down pretty quick. If the battery is really low, there might not be enough to trip the relay but will be drawing current. After things get below 8v, hardly anything will work.
Well I'm gonna take the batteries out tomorrow morning and bring them back. Where does the positive line connect to on the truck itself? Does it go to the alternator?
Nope, the more this thing keeps giving me problems, the more convinced I'm getting at not buying another ford again. I'm gonna get rid of this pig and get me a dodge with a cummins in it.
Baaaaa! buy a dodge and your problems will just begin,you will be asking somebody else about tranies ,frontends rearends,steering,can"t say anything bad about the engine .check batteries,then cables.and all connections,my ground cable on the engine side was bad .new cables are good but if the ground is bad they are useless,its a pain the a s s ,so good luck
Might be a starter that has been going junk for a while causing problems. With new batteries, cables and still having a battery drain problem.
I have seen bad starters cause trouble for months. Start one day and not the next. Start 3/4 days in a row, then nothing the next day. Start in the morning, drive to work but no start that night.
Just a quick observation along the lines of battery condition. If you have a VOM test the static voltage, should be 12.6v to 12.9v. If you just bought the batteries and they weren't fully charged you might have functional batteries that are simply low on charge. FWIW.

Don't give up too soon. If it is a battery, it has nothing to do with it Ford (at least this time). I know these trucks have their quirks but I look at the number of contractors using fords and it outnumbers/doubles the chevys and dodges combined. It might be the lesser of 3 evils but I think most owners are pretty happy, especially after owning one of the others.
Now guys, don't go trying to talk the young feller out of his dream of owning a Dodge. Let him go ahead and get one about the same age as his IDI (if he can find one that's still running and driveable, that is). Let him live with his dream for a while.
You might want to check the ground cables where they attach to the block (both lower front corners). Make sure they are tight. I'll second the ignition switch also, but if it won't start at the relay on the inner fender you've probably got something else going on.
I agree also that Dodges aren't a picnic. Wait till you get one of them and the front gear cover alignment dowel falls out. There's a fun fix.
