My car will crank but not start. I have replaced both fuel pumps. Engine oil pressure sensor. And put new spark plugs and coils. It wants to start but won't stay running.

It sounds like you may have low compression. How does the engine sound when cranking it over? Do you have a check engine light on? We need more information to help you, please go over this video to help us see what we are missing:

Can you please shoot a quick video with your phone so I can hear the engine crank over? That way I can tell for sure what's going on. You can upload it here with your response.

The engine sounds good when it turns over. It just won't stay running. And no check engine lights but I do have a lightning bolt on my dashboard. I will send a video of me cranking it shortly.
