Where is the fuel filter located on a 1993 Chevy Cavalier?

Start with filter, if not that then the fuel delivery system, fuel pump (proper pressure or no pressure), throttle body or fuel rail injectors( faild, dirty or blocked.)

gas tank

if it is a v6 it is on the front of the motor passenger side.

1993 Chevrolet Cavalier 2.2L SFI OHV 4cyl...
- The Fuel Filter is located: Under vehicle, center, below rear seating area, rear passenger side of fuel tank, mounted in fuel line
- The Fuel Pump is located: Inside the tank
- The Relay - Fuel Pump is located: Under hood, passenger side, rear side of strut tower, mounted on fenderwell

Hope helps (remember to rate this answer).

It should be on the side where the gas tank is running along the fram of the car. You should see a small stanless steel or copper line running along the fram under the car near the rear of the car. Follow it until you see the filter.

the fuel filter is neer the gas tank.....

It should be right under the drivers side door, behind the rocker panel.

should be located somewhere under the vehicle near oil pan

Spray aerosol carb cleaner into the throttle body while an assistant tries to start the engine. If it runs for a few seconds then quits, you are not getting fuel into the engine. Check the fuses. You might have blown the fuse for the fuel injectors (possible if you removed any of the injector harnesses) or the fuel pump relay.

If you have one it looks like an A/C charge port. the rail isn't very big if you don't see it it's not there!
