The ECU is not signaling the fuel system to operate. Check any fuses marked ECM or IGN. Let me know if you have more questions.

No fuel coming out of the line at the carb.


Sounds like you need to change the pump. If battery power doesn't make it work, it must have burned out. How old is the pump? It must be pretty old to still have a carburetor. Even throttle body injection that looks like a carburetor would make it pretty old?

No fuel to the injectors


Have you checked your fuel filter? It could be clogged. Has the truck sat for a long period of time? Is the fuel pump GM? Does it have enough fuel pressure? Are you sure it's not ignition related? Possibly an ignition module shorting out after it gets hot.

Cranks well but won't start.


Looks like you got spark, and gas in the throttle body made it fire: nice work.
Sounds like your fuel pump is out or the wiring is not turning it on. One way to be sure is to set a spare battery near the tank and hot wire the pump with jumper wires. Or if you have a voltmeter check for voltage at the fuel pump connector while the truck is cranking.. If the pump is working and getting gas to the engine, see if the injectors are pulsing. A good idea to check fuel pressure if the pump is working.

If the punp is bad it won't run at all. Check the throttle body injectors to see if fuel is coming out of both injectors. Sounds like one of the injectors is not working. If one is not working you can check to see if it is the injector or wiring by switching injector wires and see if the problem changed from one injector to the other.

1989 truck stalls when hot.


Have you chg. fuel filter? If so, best to do a fuel pressure test, sometimes( not always) when the pump gets warmed up they can loose a little pressure and thats all it takes just a few # under recamended p.s.i and the truck quits running, you may hear the pump run but its not putting out the correct pressure until it cools down and it starts working again, but after a while quit all together.
