Question about 1994 GMC Jimmy
U have not done the most basic test here, just replaced parts, u need to do a electronic engine control system fault code test, go to the link below and do the test and then post the results back on this thread. also perform a fuel pressure test, u will need to buy a fuel pressure test gauge, they hook up to the fuel rail test port on the tube that supplies the fuel injectors.

I would suspect the ignition module as being the problem since you already did the pump and have verified your geting fuel.
Are the plugs wet. ?? which would indicate an ignition module issue.
Are you getting spark all all. And is the spark gone after it stalls.
If you have no RPM signal when it dies you also could have a bad crank sensor but if this was the case your plugs would be dry and the car would not start and die. This condition points more to a ignition modukle issue.
Als wiggle the distributor shaft. The bearing on these tend to fail allowing alot of slop.

Do you have a chip on the key? if so you may have a security problem. very common for this error of gm to have problems with it's vats system. also the regulator would not cause only one injector not to spray. that inject is most likely clogged.
let me know if you have that chip and then we can go from there.

Check to see if there is fuel in the oil,this I believe has the spider type fuel system under the intake,if it has a broken fuel line,it will have fuel in the oil.The regulator if shut down,will cause this also.
