Question about 1994 GMC Sierra
The fuel pump is in line, replace it, it's cheap.. If it's still not getting power, then you gotta start tracing the wiring and looking for the electrical short.. Check the fuses too.. When it doubt, think cheapest first..

Did you check the fuel filter? It can be cleaned out manually. I just hold it to my mouth and blow but make sure the gunk-side is away from you.

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.

Try cleaning the throttle body and may be taking out the idle air control and cleaning that.With the time of fuel were forced to use nowadays gives us a lot of carbon build up.Have you also tried Cycling the ignition on and off a few times to see if that starts it faster.If thats the case theres still an issue with fuel..But clean all that other stuff first and see what you get..
