CHECK FUEL PUMP

pickup in tank sounds like it has a hole in it halfway down

Sounds like you lost a fuel pump, although they usually don't quit while being driven. Have it towed and get a fuel pressure check. That vehicle has to have very close to 60 psi fuel pressure to run. Have a new fuel filter installed also. Plugged fuel filters are the most common cause of fuel pump failure.

check you fuel filter.

after seven years sitting even with fuel stabilizer i would recommend cleaning or rebuilding the carb

make sure your fuel filtre okay and breather on fuel tank

look more into your ignition module and crank sensor the module is the most common problem

1993 s-10 should have a 4.3 engine. Your symptoms tell me your throttle body injector is clogged, and only allows so much fuel to pass through it. Therefore, on a idle there is not enough fuel coming through to keep the engine running, or to start it. If you replace the throttle body injector your issue should cease.

I hope this information helps you, and I wish you luck on your repair.

If vehicle was left outside or in an unheated garage, there is a strong possibility that condensation has contaminated your fuel. Easiest way to check is to remove fuel filter and pour contents into a glass jar. If you see two different layers of liquid in the jar, the bottom part is water. Replace with new filter and drop the tank. Remove sending unit. pour contents into a large container and clean out inside with clean dry rags. Remember, fuel is dangerous to work with and fumes travel pretty far on the ground. So, no open flames electrical stuff, cigarettes etc for a good perimeter around work area. Generally, you can re-use top 3/4 of fuel you removed by syphon. Don't use remainder in your vehicle. Part can be used for lawnmower etc as long as you only take the part above the water line.
