Crank No Start .
Have someone crank it while you spray starter fluid/ carb cleaner into throttle body, if it starts then you have a fuel issue, if it doesn’t try to start it’s not fuel, then probably electrical, plug a code reader and scan to get some ideas of what to chase after, either immobilizer (not sure if immobilization in the LC cuts off electricity or fuel..) or crank sensor, ignition or…
If it starts for a few seconds with carb cleaner then you can check pressure, I believe you can rent a fuel pressure tester from the auto parts stores, or get one from HF for cheap. Careful with fuel spraying all over when you disconnect a line from the fuel rails plug in tester, I believe you should see around 50psi or so, and the pressure should stay there steady. If not enough pressure, or the pressure goes down quickly after cranking, the pump is the culprit.
If fuel pressure ok and it does start with carb cleaner, you can chase after pump intermittent electrics (like relay) or might have big vacuum leaks.
Keep us posted.
