My suburban fires right off but will not stay running, it has 60 lbs of fuel line pressure with the switch on and maintains 55 lbs of pressure when key is off. Been running fine started it this morning to put my windows up and after that it did this. No codes being created, just fires and dies

The oil pressure sending unit should be located behind the distributor way in the back angled away from the engine, fuel filter been changed?

i do believe it will not start with out it if you can hook up a scan tool to it crank the engine and look at rpms while cranking should read about two hundred forty rpms thats what fires the injectors the cam sensor tells the computer what cylinder is ready to fire next also scanner will set the cam timming.
