1988 no start

After sitting for the last 6 months I decided to start the Vet. Put a new battery in and went to cranking. Seemed like no fuel. Car ran fine when parked. I pulled the air filter out and could get it to fire when shooting gas into the intake. I started looking for a fuel pump reset but couldn't find one. The 10 amp fuse tested good. Cant seem to figure this one out. Anyone with any ideas on how to proceed? Is there a pump reset on this car?
thanks

No fuel pump inertia switch there is a prime connector. The fuel pump connections are under bucket at fuel filler.

So is there anything I can check short of pump replacement?

Check fuel pressure and put a noid light on the injector harness. Before that, check injector fuses.

I have traced the wiring to the back filler can. Three wire harness. When I check for power one wire is hot when cranking. The other two wires have no power. Is this what I should find back there? I am assuming the hot wire is to power the fuel pump when cranking and the other two might be fuel gauge and ground?
thanks

What filter can? The system is hot and grounded by the ECM when it wants to pulse the injectors

you can have pressure at the rail, but the injectors must be "enabled"
