If the problem is not fuel related, check your ICM. Also, If it is the 7.3L diesel, you want want to check the ICP sensor. I am not sure if the 94's had that system on it, but it wouldn't hurt to find out. I know on a 96 PSD that I worked on, it cranked over, but it would not catch. We hooked it up to a scantool and read the error codes. Then we found out that the ICP sensor was bad. We replaced it, and then it started. There was a system that the PSD's had that determined how hard to inject fuel based on oil pressure. The ICP sensor is what measures that. Other possible causes:

Bad ground

Bad-Corroded Wire or Bad Connection

ECM Malfunction

Malfuntioning Fuel Pump

Plugged air filter (rare)

The ac could be causing the problem. Turn the ac off, and watch the compressor clutch to see if it is not engaged. If it is then the compressor or clutch could be bogging the engine down.
