93 Chevy 350 V8 wont start

I have a 93 Chevy K2500 with a 350 v8 that won't start. At first i wasn't getting spark but I replaced the ignition coil and fixed that problem, but now i'm not getting any fuel out of my TBI. I replaced the fuel filter and fuel pump the other day and still not getting anything. Possible ECM or injector problem?

Test for injector pulse using a small bulb called a noid light. If none found, check for power supply at one side of the injector with the key on.
Use a fuel pressure gauge to test for correct fuel pressure, also noticing if the pressure holds when key is shut off.

Do you what the correct fuel pressure should be? And could a bad fuel pressure regulator cause the injectors not to fire?

9-13 PSI on a tee tap, not dead headed.
