Question 96 gmc service engine light

Have a 1996 gmc 1500 x-cab PU 4.3 litre engine. ever since i ran out of gas the "service engine" light has been on. How do i get it off? I would think it has something to do with the engine stumbling while it ran out of gas. Any suggestions would be appreciated.

You need a scanner or code reader to check OBDII codes.

Running out of gas is bad business on a fuel injected vehicle. You might have wiped out the fuel pump by starving it for fuel which removes the cooling and lubrication the fuel provides the pump.

Check your fuel pressure with a reliable gauge and see what you have.

Running out of gas can cause a P0300 "random misfire" code.

The light will go out by itself after a few drive cycles if that's the problem.

If it runs ok, drive it for a few days & see if the light goes out. If it doesn't go out after a few days, or if you have an engine performance problem, head to Autozone & ask them to retrieve the codes from the PCM. This is a free service. Post the codes here & we'll help you figure out the problem.
