    Default 96 suburban engine died while driving on freeway

    Tried to start after pulling over, no success. I had it towed home and check for spark, ok. I checked to see if fuel pump was working, ok. I check little air valve looking thing on fuel line in engine compartment and got fuel to squirt on ignition. I checked air filter, ok. I took off cover to top of carb, and primed w/gas, engine started for a little while. Is there a simple fix to this problem.

    My guess would be a clogged fuel filter. When's the last time you changed it?

    He said when he checked the schrader valve on the fuel rail that fuel squirted out which means there is pressure and the truck should start. Sounds like the injectors are not firing.

    There may not be enough pressure for the injector to spray. Who knows, it may very well be a crank sensor causing no pulse to the injectors. Checking for codes would shed some light on it.

    Agreed, a check for codes should always be the first thing done.

    Check actual fuel pressure. Low pressure will produce a squirt at the schrader valve on the the fuel line but might not be enough to start or sustain running of the engine. As posted earlier replace your fuel filter if you haven't done so for a while. Dirty fuel filter can greatly reduce the fuel pump life as can operating the vehicle when your fuel level is below 1/4 tank.
