Hi All

I've got a 79 Trans Van (the B300 I believe), and it just recently started giving me fits. It'll crank and crank and crank until it starts to sounds sluggish, but never turn over. I got some of that carburetor spray, gave it a little blast, and it fired up for a second and died out.

I'm thinking it's the fuel pump, but I'm wondering if anyone has experienced something similar before I go replacing parts.
