It sounds like your batteries are rundown, and to start you need around 200 RPM cranking speed. Try and get a boost to your batteries by jumping with another truck, or change your batteries out for new ones.
If you haven't already, check your fuses. Replace any blown fuses and try again.
Have you ever changed the fuel filter? If it has been a while, try changing the fuel filter. If you decide to use ether to start the engine, be very careful. Spray a small amount on a rag and place it over the intake of the air cleaner. DO NOT REMOVE THE AIR CLEANER! On engines with glow plugs, if the ether flows into a cylinder with the intake valve open and hits the red-hot glow plug, you have a fire! If the engine starts with the starting fluid, you have a fuel problem.
Check each glow plug for continuity, either with an Ohm meter or a test light. Test the glow plug leads for continuity as they incorporate a fusible link.
On the 7.3's, it is common for the heater element to fail, which can cause a fuse to blow. Try unplugging the heater and the fuel bowl heater.

Have a load test done on the batter to check for failing cells. For diesels to start any thing less than a fully charged battery good battery is a waste of time as the engine needs fast RPM to heat the air to ignite the fuel and slow rpm's just doesn't cut it.
Are you waiting after turning ignition key on before actually moving key to start position? My diesel I turn key to 1st position;bells and lights;if engine is cold an amber light that looks like a lamp filiment comes on...wait until that light goes out before engaging the starter.
hi i have a 2004 2.5 turbo diesel ford ranger ,while driving on the highway a major power loss ocurred now feels like a 1.3 uno cant feel turbo engaging at all i removed the turbo and took it to a specialist he says its fine ,could it be the diesel pump or what else can it be
Charge the batteries. take a Reading to make sure that you are getting almost 14v to both batteries. If it is not charging then take the alternator back off and have them check it. you might have bought a bad one. There is a way to test the glow plus with out taking them out. ( Take a piece of wire long enough to reach all the glow plugs from the battery. unplug the glow plug wire.If you touch the end of the glow plug with the hot wire it should make a little spark. if no spark then the glow plug is bad. do this to each one, but one at a time)
