Fuel problem with 02 Chevy pickup v6

Could be no power to the fuel injectors, did you switch out the computers from the original cab? I think you have no power, pulse, at the fuel injectors.

Thank you.can. you tell me where I need to look for the computer and is there anything else that that I might need to know. Once again THANK. YOU

Usually along side of the glove box. Take the glove box out. But you should check for a pulse at a few of the injector connectors first. They use a noid light for this, not sure if a digital multi meter works or not, you would be looking at somewhere around 5 DCV. I would think putting a test light across the injector terminals would light up the test light, it would blink. And you would need someone turning the engine over for testing. There is no pulse unless it is being turned over, or running.
