For initial prime, you have to check fuel pump relay and wiring circuits. The control/coil side of relay gets voltage from pcm, green wire with white tracer. The ground for control side of relay, should be a chassis ground. Voltage for load side of relay is fuse protected.
This vehicle has an oil pressure switch in fuel pump circuit, just a redundant power supply to the fuel pump. Even w/o the relay the vehicle should start and run, once the oil pressure builds up and that switch closes, the fuel pump will get voltage. There won't be any initial prime w/o the relay.
93 chevy astro van rear door linkage not working
What has happened is that the link rod connector, a plastic piece, has broken, and the rod is indeed flopping around in there. These are always fun, as they never break after the door is already open; it is always the act of opening the door which breaks them. The parts are cheap, less than $5, but getting to them...not so great.
To further assist you, I need to know which rear-door configuration your van has. Please respond if you still have the vehicle and the problem.
