Do you have power at the injectors? You should have 12 volts on one side of the injectors and then the PCM grounds the other side to control when it and how long it opens.

So let's test the injector and make sure it is pulsing like it should when you are cranking the engine. Here are some guides that will help with this:

When you crank the engine does it turn over and just not start? If not then you may have an issue with the ignition switch.

Let's find out about the injectors and go from there. Thanks
