It will not start. I can put fuel down throttle body it starts. It has fuel pressure, all fuses and relays are good. It is just not injecting fuel.

Good morning.

What is the fuel pressure?

Is the check engine light on?

Did you check for power to the injectors? They are supplied with battery voltage. The ground is controlled by the ECM. When the ECM sees a crank signal, it grounds the injectors to let fuel flow. You can use a Noid light to check and see if the ECM is toggling the ground on the injectors. You can get a Noid light at a parts store and the test is simple.
