Have you had the trans cooler and lines checked? I believe on the 94 the cooler lines run into the rad, so there could be a blockage or your rad is not cooling properly

SOURCE: 94 GMC truck diesel starts,runs and then dies and will not start

I have the same problem and have trouble codes 35 and 36. I found out that there is a computer module that needs replaced as it sits low in a valley and gets hot and seperates. I am reseaching about the a/m fix that installs the new module away from heat.

SOURCE: 1997 Chevy K1500 Z71 Chevy fuel injector problem

Did you check fuel pressure to make sure you are getting proper fuel pressure? If it will start with starting fluid then it has to be either fuel related or electrical. Are you getting power to your fuel relay? When you turn the key on can you hear your fuel pump come on? I would not use anymore starting fluid at all to try and start it other wise you cause major problems.

Fuel Cut Solenoid: Testing and Inspection
An inoperative shutdown solenoid can cause a no-start condition. Disconnect solenoid harness connector and with ignition switch in the "ON"
position momentarily touch solenoid harness connector to solenoid connector. If a "click" sound is heard, the solenoid circuit is operating
properly. If "click" is not heard, the system should be diagnosed as follows:
1. With test lamp connected to ground and the ignition switch in the "ON" position, backprobe the shutdown harness connector. If the test lamp
does not light check for open circuit form the ignition switch to the solenoid.
2. If the test lamp lights, check the ground circuit between solenoid stud and injection pump cover to see if connectors are clean and tight. If the
connections are not clean and tight repair and retest.
3. If the ground circuit is "OK", remove the injection pump cover. Connect a jumper wire between solenoid ground connector and ground. With
the ignition switch in the "ON" position, momentarily touch shutdown solenoid harness connector to shutdown solenoid terminal. If solenoid
operates, check for internal injection pump problem.
4. If the solenoid will not operate, replace the shutdown solenoid.

SOURCE: 94 Chevy 1500 truck, seems to be getting fuel,

These sometimes have problems with the magnet on the distributor shaft loosing magnetism. This causes the pickup coil not to be able to produce a strong enough signal for the ignition module and the engine dies because of no spark.
