I have a 1994 silverado 2wd with a 5.7 liter engine.

It sat for nearly a year with transmission issues which are now repaired. The butterflies in the throttle body were frozen so I replaced it with one found in salvage shop.

It started up and ran for about 10 minutes before stalling and not starting up since (at least not for more than a moment). Fuel is not spraying from injectors when trying to start, but is getting up to the throttle body itself (removed line and turned key to turn on pump to check)

things done:
-emptied fuel tank and lines
-replace fuel filter
-replace throttle position sensor
-replace IAC
-replace engine coolant temperature sensor
-tested ignition control sensor (at autozone) tested fine
-tested voltage at injectors (12)
-checked filters in injectors (clean)
-checked fuel pump, (operational)

What would be the next step in my seemingly never ending repair journey I have embarked on?

 

The next step I would do is check the fuel pressure to see if it is in spec. There has also been trouble with the injector wires breaking.

 

noid light test on the injectors proves that the wiring is ok.

I guess the next step will be to get a pressure tester on loan from the parts store.
