Check for power to the Fuel Injectors. They should be hot anytime the key is on. The PCM provides the ground. If the injectors have power, then something is keeping the PCM from providing the ground, such as a PIP signal ect. If the injectors do not have power with key on, then there is either a blown fuse or bad wire in the circuit.
 
See #5 on this list.
 
Saw this here before and it was related to a wire behind the drivers kick panel. Not sure if it's your issue. Green with yellow stripe wire. This is someone else's photo from a previous thread.

The injectors have 12 volt on the red wire to all injectors.
