Already changed the crank sensor and the module under the coil packs

I have great spark and fuel pressure is 40 lbs

I'm afraid to tell you that if you had already replaced the crank sensor, the ignition module and there are no codes, then most likely you are looking at a bad ecm/pcm.
Expert:  Mike S. replied 7 months ago.
Are you sure the ecm/pcm is powering up? Does the check engine light come on for bulb check?
Customer: replied 7 months ago.
Thasbwhat I was thinking knowing the ground for that circuit comes from the ecm I was afraid of that but thank you for your info . Have a good afternoon
