i would check the idle air control solenoid first. simply unplug it then remove the unit and inspect the air passage for any blockage and carbon buildup. Clean it if its dirty then test it out. If the IAC is good then you should look at the throttle position sensor.

1991 subaru legacy, the engine cranks over but will not start


Is the check engine light on? If so, rent a scanner, read out any code(s), and pursue to repairs. If no spark or fuel, suspect either the camshaft or crankshaft sensor to be defective (should show up on the above scan).
