Vehicle has been running very well and driven daily. Parked it over the weekend. Monday morning would not start. Engine turns over easily, but will not hit. When carburetor primed with gas or "Engine Start", engine starts for a moment and then dies.

What is wrong?

With the engine cranking, can you see an injector spray pattern? If no spray pattern, check for voltage at the injector plug/s. At one injector, the voltage wire is white, at the other it is red, goes hot when you turn the key on. The computer controls the injectors on the ground side. If no rpm signal, the computer won't ground the injectors. The rpm signal comes from the ignition module.
