Does it just go between 2000 and 3000 or does it go above and below, i.e, if you rev the engine is it possible to go above 3000 rpm or does it just stick there? Does it drop below 2000 rpm when you engage the tranny and prepare to move on. I guess what I am saying is that if neither of the above occur, then your tach head is either incorrectly wired or it's fried. Is the seven volt reading with the engine running or with the key on w/o running engine. Need more info.. BTW, what is your idle speed set at???
