Any Corvette guys out there lend a hand?

I have an `88 Vette here that will not run for crap. It seems to be fuel pressure. But here`s the strange part, I have pressure at the fuel rail, but there just seems to be air in there, not much fuel at all. Does anyone know were the fuel pump is on this unit, how to get to it, and what would cause the pump to just pump air??
The guy stopped at the station and put $20.00 in on his way over to my shop so it shouldn`t be out of gas. Thanks for any responses.

The fuel pump is accessed through the fuel filler door/cover.

It sounds to me that it is the fuel pump especially if there is more air in the line than fuel. The pump is supposed to provide enough pressure to prime the line full of fuel before start up.

anyhow how new is your fuel pressure regulator? it could be allowing air into the line.

The fuel regulator would leak fuel to the outside before it let air in, wouldn`t it?
Thanks 6QTS11OZ, I prolly would have gone from the wrong dirrection and pulled the spare tire and tank down.

I`ve only got 28 lbs fuel pressure with a TPI system when it`s running so I`ll put the pump in.
