Q: Cranks but not start on 1997 Chevrolet Suburban 1500

Rookie cbe0621eac06868b3efe0d8d1d3611e23c60d3114864ea2ec19a68cfbd3eebab
This problem just started. Parked at store, 2 hours later will not start. Had a code P1345, cleard and not returned. Replaced fuel pump and filter. No help. Fuel pressure is 55-60. Good spark. Will start and run if fuel is poured into TB opening. While running this way if throttle is pressed engine will die as if out of fuel.

fuel pressure for cold start must be no less than 62lbs. vehicle will run at 45psi after engine is warm. check pressure regulator. if reg. holds steady, most likely fuel pump is weak.
