If you have good spark and good fuel pressure and it starts on carb cleaner then the injector is not working or you are not getting injector pulse.
You need to start checking the injector pulse.
A scanner or noid light is the only to check for injector pulse.
Parts place will sell thm or rent them.
Good luck MT

In responce to your priviate message.
You need the injector noid light or a good scanner to check for injector pulse.
A test light will not do it and a may damage pcm.
Any parts place will have them. They are a little noid light that will blink if there is injector pulse.

You have to have the injector pulse and proper fuel pressure for the injector to squirt fuel.

No sense trying to diagnose fuel injection problems without one. Not very expensive considering the amount of time to be saved or $$ throwing parts at the problem. BAT Looks like a good source for tools. I bookmarked it.

We figured it out. We had spark but we switched ignition modules from our parts vehicle anyway. Problem solved. Thanks for the help!
