Engine starts and runs for just a few seconds then dies. I replace fuel pump, regulator, crank senor, coil packs. Any advice would be great.

sounds like a fuel problem.... you replaced the fuel pump, how about the fuel filter???? also, check the fuel pressure... the 94 4.3 assuming its a vin # W has a fuel spider which usually cracks and leaks fuel into the intake manifold... however that usually only causes it to hesitate while accelerating.... also, if your looking where to test your fuel pressure, it is behind the upper intake, near your distributor cap.... let me know the results.

I changed the fuel filter and the fuel pressure was good.

being a 4 cyl, a bad injector can cause these not to start.... ive seen it before, but most times it starts, and sputters..... dont rule out the crank sensor you replaced... i know its new, but it may be defective.... did it run before you did all this work?
