Have you checked the “INJ A” fuse in the under dash fuse panel?
Is there power to the red & white wires at the injectors?
If there’s power; install a noid light to the injector harness plug & see if it flashes as you’re cranking the engine.
Is the ignition ok; as in a good spark?
Here’s a pic of a noid light kit. They’re more or less a very low amperage test light that will not hurt the computer; designed specially for testing injector pulse.
