No, not yet. The problem could very well be an unreliable electrical connection, (and since you didn't say it began working *when* you kicked it) a bad tank selector switch, or the fuel pump relay. The pump itself may be fine.
Checking the relay is simple. And assuming the fuel pump is situated similar to other in-tank pumps, the replacement job is a serious undertaking for someone unfamiliar with it.
Also (and I'm referring to the the arrangement in an older truck; you need to look up the connections for your year and engine), you should be able to jump two leads (connector 2 & 6) in the test connector to make the fuel pump turn on and *not* turn off after a brief interval.
