Check for a bad crank sensor.

If the computer doesn’t see crankshaft rotation, the computer see’s no reason to operate the fuel/ignition systems.

Other possibilities besides the crank sensor

- System voltage problem. Ask your shop to verify the battery measures about 12.6 volts before the first start of the day, then 13.5-15.5 immediately after starting the engine.
- IGM 2 Relay
- Camshaft position sensor (intake side)
- Camshaft position sensor (exhaust side)
- Wiring harness/grounds
- ECM
- All the coil packs are faulty (seems unlikely)

you need to seriously consider replacing the crankshaft position sensor . . . even if there are no fault codes pointing to it

may I assume you’ve verified fuel pressure is correct?
