Thank you for allowing me to assist you, my name is ***** ***** I will be happy to assist you with your concern today.

I would need the engine model number to which you have, however with what you have explained I at least have an idea that your working with an tbi system since the fuel injectors are in the throttle body. The first things are to do is check fuel pressure with a fuel pressure tester to confirm pressure and getting to the fuel rail, next is using a noide light to confirm injectors are being sent signal to fire, your checking pulse and ground on these if a noide light shows a problem.

This should at the very least if not find the problem will help us narrow it down and then preform further testing.

Thank you!
