2003 Silverado Fuel Pump

[75sierraclassic]

Over the past 6 months, maybe 4 times, my truck hasn't started. On the first key turn, Engine turns over but doesn't fire. Second key turn, sometimes it starts. If not on second, then third time it starts. Worried that the fuel pump needs replacement (170,000 miles). Thinking its gonna need it soon anyway so why not replace it before I get stranded somewhere.

Whats the easiest way to do it? Drop the tank or just take the bed off? Is the pump and sender in the tank? Should I replace sender also or just replace the pump?
