CHEVROLET SUBURBAN ENGINE PROBLEM

2004 Chevrolet Suburban

I just rebuilt the engine and when I cranked the car the oil pump wasn't pumping oil. Have I ruined this rebuilt engine now and do I have any alternatives besides redoing everything I just rebuilt? It sounds terrible when I crank it (lifters, etc)

Thanks

You need to get oil pressure before you start the engine or it will sound bad. Once you get pressure, it may be fine. NOTE: Do not continue to run the engine without oil pressure.
