Crankshaft position sensor AND it's connector. Easy, fairly cheap and frequently the issue on the 2003 Express. There is a known issue with the wiring harness and these connectors (cam sensor, crank position sensor and ABS) used on this particular year. Other known issues include ABS problems.

What is standard running fuel pressure on 4.3L v6?


Nothing wrong with fuel pressure should be fine. Pressure should not bleed off when vehicle not running that is probably why you have to crank for a while before it starts. I would check all fuel line connections from tank forward as you have a pressure "leak" somewhere along the line to loose fuel pressure.
