The answer I'm giving is based on my 1994 GMC Jimmy, which is still the "square" body style. The fuel tank holds 20 gallons as far as I know.
If your engine light has come on for your 1993 GMC Jimmy, you need to take you car in for service. You should make sure that you have enough oil in your car.
It wont shift because its leaking fluid.
It could be that your EGR valve has failed or has a piece of carbon stuck in it .
