Your fuel pump is sticking and not pumping, this is common if you run the fuel down to less than 1/4 full, the fuel pump needs the gas to cool itself, below a 1/4 tank the pump is not getting cooled and after repeatably running low on fuel it overheats and fails. Running the car near 1/2 tank extends the pump life to many years more than running tank below a 1/4 full..

Assuming it is a fuel problem I checked at the carb. to be sure no gas was being pumped through the filter located under the power steering pump then the fuse on my 87 s10 was the ECM fuse.then check for the relay to click and the had to replace the oil pressure sending unit and mine started right up..the oil pressure must be about 4 lbs for the Pump tp operate...I loosened the fuel line to ck. for fuel but thats living dangerously...a pressure guage would be on the safe side......

Turn your key to the "on" position and listen...you should be able to hear the fuel pump running. If not, I would like to say to check a relay, but the hard starting was probably an indication that the pump was going bad and it most likely went. If the pump is running, I would replace the fuel filter or get a fuel pressure test at the fuel rail. Hope this helped, sorry for your troubles, and I hope you find a resolution to your problem that is not too painful.

It sounds like there is a problem with the Idle Air Control (IAC) valve. Its job is to open and let air into the manifold when the throttle is closed at idle. If it does not open, the engine dies at idle. The IAC is mounted on the throttle body. Possibly the valve is clogged or stuck, in which case it could be ok again if it is removed and cleaned. Or it is broken, and needs to be replaced. Or, there is a problem with its electrical connection, that needs to be traced. Good luck, let me know if you have any questions.
