Cranks all day but no start. No codes, no blown fuses, no bad wiring, new crank and cam sensors. All electronics work fine. No check engine light. Any insight would be greatly appreciated. We have hit above 90 and just to hot for me and my service dog to walk. Thanks in advance.

How old are the air and fuel filters? Is the fuel pump working and is pressure OK? Does live data show engine RPM while cranking? If you spray some starting fluid into the intake and crank, does the engine briefly fire up?
Air filter and cabin filter are fresh. I hear the fuel pump engage when I turn ignition. I don't have live data on my scanner. I haven't sprayed the starter fluid in the intake. It turned over and ran a short time then stopped.
The starting fluid is a quick and dirty way of determining where the problem may lie. If the engine will run briefly with starter fluid then you have spark and the problem is fuel delivery. If it doesn't run you have no spark. The RPM check in live data will tell you if the computer is receiving information from crank and cam sensors.
