Using ether with an engine with glow plugs is a bad idea. Try cycling the glow plugs by letting the "wait to start" light go out, then turning the ignition switch to off and then back to run again. That will add more heat to the cylinders before you start. You might need to do that a couple of times. If that doesn't work, and you must still use ether, go easy with it. Too much at once can cause rings to crack, then it will need it all the time when you start cold. In the winter it will be almost impossible to start if it has been sitting for any length of time. The best way to give it an ether shot is with one person cranking the engine, and another giving very short, i.e. less than a second, shots of ether through the air intake. Another method is to douse a rag with ether then hold that over the intake as the other cranks the engine. If you are a solo operation, a gentle squirt, then run around and crank before it all evaporates. The major drawback with this method is you DO NOT want your glow plugs to activate when you turn the key, so wait for them to go out before the ether dose.
As for testing the glow plug system, the dealer can do that by hooking up to the diagnostic port, or any GM certified shop for that matter since the engine is the same as what went into the pickup and Suburbans from that time.
