Sounds like it could be the Idle Air control valve. Also could be leaking air into the fuel injection somewhere.

How do I change the fuel pump in the engine on a 1990 Chevy Caprice Classic wagon


The fuel pump is in the fuel tank. You must drop the tank to access the pump. Make sure you drain as much fuel as possible before you drop it completely, it will be much easier to handle.

No power tp the fuel pump, injectors not pulsing, no fuel.


Check out your oil sending unit, fuel pump and relay, check for power (might be a fuse), the ignition control module (which if you remove it, can be tested for free at AUTO-ZONE), any related wiring, pick-up coil (inside the distributor), and possibly the ignition switch. If I can be any more help just as away.

Also do not let tank run low because fuel in tank keeps in tank pump cool. This is why the pump is in the tank.
