My truck started out idling to fast, then it would die out. It has completely died out while driving on the road. Over the weekend I got in my truck the idle went up real fast then it died.I tried to start my truck again and it cranks but won't start at all.I'm a Veteran and can't get to my VA appointments my truck is not reliable right now.
I've changed many parts. Fuel pump, Inertia switch, Battery, Solenoid, Distributor.I have even moved my EEC and Fuel Pump relay around and still nothing.I'm just not sure anymore what the problem could be.
I could use some help on trying to resolve the problem, can you help thanks.

I have to ask, how long since a tune-up? Are there any applicable trouble codes? If it cranks good but won't start, have a helper crank it while you check for spark at the spark plugs, if spark everywhere, use a gage and check proper fuel pressure and fuel injector pulse. Check and clean anything that has to do with idle air system, check maf and map where applicable. Sometimes a vacuum leak can cause problems.

Why wasn't the code test conclusive? If your eec iv, there other ways to check the codes. Diagnostic connector right front inner fender panel.
You can use a test light or analog volt meter. Hook it up, turn key just till dash lites come on, then the test light starts flashing or the meter needle starts sweeping. You count the flashes or sweeps to get the codes. It does take some practice to get used to reading the pulses, correctly. After you get used to it, you shouldn't have any problems.

If a fuel issue, use a gage and check proper fuel pressure, also check fuel injector pulse. Did you try checking codes like I suggested?
