Why would a 1989 escort not be getting fuel?
A 1989 Ford Escort would not be getting fuel if the fuel pump has failed or the filter is clogged. A local mechanic or dealership can diagnose and repair the problem.
Why would the fuel cutout light come on on your 1989 Ford Escort GT and how do you go about fixing it?
Does the car start? because if it doesn't... then your fuel cutoff has been tripped, likely by the car getting hit closer to the gas tank and tripping the cutoff valve. if it's anything like the cutoff in a '91 escort, you should be able to take off the small panel access in the trunk/hatch and reset the switch, if it's the same, it's pretty easy
You can't and you shouldn't. The MAF signals the computer how much air is going to the engine. The computer adjusts the amount of fuel going through the injectors. If you were to by pass it, you would either be getting no fuel at all or be getting the maximum amount of fuel. Either way it would be bad for the engine.
