When you pour fuel in the intake the truck runs but when the fuel is burned the engine stop. I seem that you fuel pump has a problem. first chack the fuse for the fuel pump if it is burned up replace if not check the fuel pump relay. take a volt meter and check the resistance of the relay if it is between 40 to 80 ohm it is ok then take two jumper wires and apply and ground to two terminals at a time on the relay if the make a buzzing sound, the relay is good. go to the fuel tank, have some one try starting the truck and listen to the fuel pump. if the pump is working you will hear sound coming for the tank. if not disconnect the two wires that fuel the pump with power and ground. use a jumper wires from the batter apply power and ground to the pump if it work then the pump is good, if not replace.

I have 1993 chevy 4.3 pickup that about every three years does the same thing it was the fuel pump relay located on passenger side of firewall under a plastic flap. I went to parts store told them my vehicle and got relay took 5 minutes runs fine again Semper Fi!
Fuel pressure is a little low. Will it start with a couple shots of carb spray in the throttle body? If it does and continues to run than the fuel pump is not providing enough pressure to to open the mechanical poppet valves on the end of the injectors. minimum fuel pressure is 58 psi. One PSI below spec is enough to make it not start.
Also check to make sure there is spark at each cylinder. just because there is spark at the ignition coil does not mean it is getting the the spark plugs. you may have a bad cap or a rotor that is burned through.
a 1997 c1500 doesnt have a carb it is fuel injected, you poured fuel into the throttle body. when you turn the key to the start position and you do not hear the fuel pump you could have a blown fuse. if not, all chevys have passlock a passive antitheft system that have locked the fuel system down. check some remote start companies on the internet you will find one with a wiring diagram, you can figure out the rest from there. its eas
hi, check the connections at the ecm,i think it's under pass front seat,i've had a couple of those years loose injector signal at ecm connector,if you have a test light you can unplug injectors and test across terminals ,it's a 12v signal at inj ,if lights flash on both while cranking try plugging in one at a time and see if either sprays, if one does and not the other, you would have a shorted injector
1993 s-10 should have a 4.3 engine. Your symptoms tell me your throttle body injector is clogged, and only allows so much fuel to pass through it. Therefore, on a idle there is not enough fuel coming through to keep the engine running, or to start it. If you replace the throttle body injector your issue should cease.
I hope this information helps you, and I wish you luck on your repair.
first of all make sure battery is fully charged auto zone will test batteries for free but if you can get it jumped and running while it is running take the positive side cable off the battery and if it dies then it is the alternator and also look at the condition of the drive belt but if you do all this and the truck does not start spray very little starter fluid in the throttle body if it starts ask yourself when was last time I changed the fuel filter and also have someone to be back by the gas tank to see if you can hear the pump and check out the fuel pump relay which is normally under the hood on the drivers side before changing the fuel pump
