99Whistlindixie

Looking for input, recently replaced my vp on my 99 1 ton ramp truck. Sat for year as I was out of town most of the time working . I also replaced the timing cover gasket and seal and installed a wear sleeve on crank . While I was cranking to bleed fuel system I noticed checkgauges light on and no oil pressure while cranking which I could not remember if was always like that or not . So I pulled filter and cranked . No oil pressure , then pulled the relief valve out and cranked . No pressure there . Now have it torn back down and pulled the oil pump to check for damage . Nothing noticeable. Not sure where else to check . Thinking I will replace pump and pull pan and check pick up , really hate to throw parts at it. Any help appreciated
