The car seldom starts until noon or later, after it has been in the sun for 5 or 6 hours, and sometimes not even then. Once it has started, it runs very well and I can turn it off or on without problems the rest of the day.The problem reappears the next morning: the car cranks well but the motor does not start.Temperatures here average 60-70 F. at night and 75-90 in daylight. This car has a dealer-installed alarm since 1994, which appears to work partially and could be causing starting problems. Can this alarm be eliminated without losing the ability to open doors remotely?
Run the fault codes to check for the problem
Most likely in the ambient temp sensor , baro sensor or MAF/VAF sensors

on both a 7.3l and 6.0l oil pressure is everything. Both engines use two oil pumps one for lubrication and one to fire the injectors. if your high pressure oil pump (inj pump) is weak it will take a long time for the truck to start. In order for the ficm to fire the injectors it wants to see at least 250 - 400 psi of ICP pressure. you will need a scanner to determine your high oil pressure at crank. Let me know how you make out.

this may sound funny but i had an old dodge car that did that exact thing....turns out that i had to replace or repair the ground straps and also the cables to the battery and starter....it was fine after that.

When it wont start one day poor gas or starter fluid into injectors if it starts up it could mean you need to replace fuel injectors.

This is due to the fact that it possibly hasn't gone for a check-up in quite a long time. There are only two things that can cause this kind of problem and they are
1. If the battery is low or the kick starter is bad. A very good way to determine if the battery or kick stater is good is to watch out for the sound that the engine produces while you keep trying to start the vehicle. If you notice any kind of slow winding of the engine gears(i.e sluggish sound instead of usual energetic sound). A bad kick starter would lead you to keep trying to start the engine and eventually make the battery to die.
secondly, there might be a problem to your fuel supply. It might not be supplying enough fuel into the combustion chamber (be it carburetor or injector) therefore limiting the supply of available fuel to start up the engine.
The best thing to do is to send it to a mechanic to run a complete diagnosis on the engine to know if there might be any other issues as this is a very old engine and requires delicate care.
Hope this solution was helpful to you? Please comment for more information
