Hard starting 87 TBI Suburban

My 87 suburban with a 350 TBI has an odd problem I can't nail down.

If I get in, turn the key, and crank it won't start for a good 5 seconds.

BUT if I get in, and only turn the key to the crank position for a second, wait a second, then do it again it starts instantly.
It seems like the pump isn't priming unless its cranking?

Any ideas?

Sounds like a fuel pump that's getting weak.

Yep that's the same thing I was thinking. Did you listen for the pump priming when you turn the key yet?
