It sounds like you have removed the injectors. how can you tell an Injector is not working? Also is it one injector or all of them? If just one, it could be clogged here is how you can change it out.
Description:
The fuel injector driver receives an inject command signal from the Powertrain Control Module (PCM) and provides a current regulated output to the fuel solenoid that controls injection. It also returns an injection pulse width signal back to the PCM to inform it when the fuel solenoid has actually seated.
A scan tool will display the injection pulse width feedback in milliseconds. If the PCM detects an error in the fuel inject response time, a DTC 35 or DTC 36 will set.
Let's run the codes as well.
