I had a similar problem with an S-10 some time back, and I understand that the 88 C1500 has the same fuel pump setup. Two questions you must answer: First, did it run out of gas just before the problem started? Second, if you remove the air cleaner cover and pour just a little gas into the carb/throttle body, will the truck start and run until the gas is used up? If you answer 'yes' to the last, or to both questions, the problem may be in the electric fuel pump mounted in the gas tank. In my case, when my son was driving the truck, he would let the fuel level get really low before putting gas in the tank. Fine contaminant particles would build up on the fuel screen, and caused premature pump failure when some of the contaminant particles passed through a small hole in the screen and wrecked the pump impeller. Give it a look-see.

Chevy Tahoe 2000 Z71 won't start!


Just for the record, its a throttle body not a carb.
Sounds like the injectors are not getting power or a ground signal from the computer.
You would check them with a meter or low voltage test light.

Won't start up


Check to make sure you are getting fuel pressure. Can you hear the fuel pump come on? Will it start with carb cleaner being sprayed in the carb (watch for back fire)? If it will start with carb spray and you can not hear the pump its the pump. Try to get it to go like a old stuck starter. Have someone turn the key and use your fist to bang the fuel tank sometimes that will get it to go. Sounds like you need a pump.
