This is not difficult, well, too difficult.
1. Does the SES/ck eng light come on when the key is switched to the run/on position? If it doesn't, then you have a power problem to PCM,(been there).
2. Does the SES light go out during cranking? Light stays on-no CKP signal, light goes off-PCM getting CKP signal. No CKP, ck connector for oil contamination/leaking CKP.
If that cks out, ck fuel pressure, spark, and injector pwr/pulse. Main thing is to have some sort of pressure gauge, the other can be diagnosed with a DVOM/test light/noid light.
