You can check the trouble codes for your 94 Ford Escort LX without the use of a code scanner. The 94 Ford Escort LX comes equipped with the first generation On-Board Diagnostics (OBD) computer. This computer receives and stores trouble codes sent to it from sensors positioned throughout the vehicle. These trouble codes are sent when the sensors detect a malfunction in the Escort. You should always read the codes first to diagnose the trouble, then fix the vehicle before resetting the OBD computer. The computer communicates with you via warning and service lights that appear on the instrument panel. If you ignore these lights you may risk further damage to your Ford.

Instructions

1

Put the key into the ignition and turn it to the "on" position but dont start the engine. Pop open the hood and prop it up with the safety bar.

2

Find the six-pin receptor Self-Test Output (STO). Next to that output is the small, one-receptor Self-Test Input (STI).

3

Examine the STO and find the two outlets on the bottom. The outlet on the left, as you are facing it, is the ground outlet. Use the jumper wire to connect this ground outlet to the STI.

4

Sit in the drivers seat and turn the key to the "Run" position. Watch the instrument panel while the "Check Engine" light flashes and count the number of flashes. This is the first number in the code. Write it down on a piece of paper. There will be a couple of second pause then the "Check Engine" light will flash again. Count the number of times it flashes. This is the second digit in the code. Write down this number. If there are more codes to follow, they will be separated by a four-second pause.

5

Look up the meaning of the codes in any 1994 Ford Escort LX repair manual.

The fan belt on the 1994 Chevrolet Blazer not only turns the radiator fan, it also runs the alternator, water pump and other accessories located on the engine. This type of belt is called a serpentine belt because it resembles a snake by wrapping around so many pulleys on the engine. Over time, the belt can experience dry rot and cracking, despite being lined with steel braiding. Replace the belt, if it appears worn, to avoid getting stranded on the road.

Instructions

1

Map out the serpentine fan belt, noting how the belt wraps around each pulley. The serpentine fan belt is located between the engine belt and the radiator fan. Sketch out a diagram on a piece of paper. A diagram is also printed on the underside of the engine hood or on the fan shroud, but it may be missing.

2

Locate the tensioner pulley. On the 3.8-liter engine, the pulley is located between the alternator and the power steering pump. On the 2.8-liter engine, the pulley is located between the alternator and the air conditioner pump. The pulley has a square hole in the center of it. The diagram on the underside of the hood also shows the location of the tensioner pulley.

3

Place a 3/8-inch ratchet drive into the square hole and set the ratchet setting counterclockwise.

4

Pull up on the handle to release pressure on the serpentine belt then slide the bottom of the belt off the tensioner pulley.

5

Remove the belt from the rest of the pulleys then place the new belt onto the pulleys. Follow the belt routing diagram to ensure each pulley turns in the correct direction.

6

Pull up on the handle of the ratchet and slide the belt under the pulley. When you release the ratchet, the tension pulley applies tension to the belt.

You can get the engine codes from your 1994 Mercury Sable right from home using an OBD I scan tool. This tool can be found at any auto parts retailer. When you see the "Check Engine" light illuminate on your instrument cluster, this is an indication that an error code has been sent to the vehicles On-Board Diagnostics computer. Never ignore a "Check Engine" light, or you may risk further damage to your vehicle. This same scan tool can also be used to reset the computer, and turn off the warning light after you have retrieved the codes and made the repairs.

Instructions

1

Plug the OBD I scan tool into the diagnostic port under the steering column just to the left side of the fuse panel. Check to see that the connection is tight and secure, but dont force the cable into the port, or you may risk damaging the pins.

2

Put the key into the ignition, and turn it to the "On" position. Wait for the scan tool to interface with the computer, and then display "OK" on the face of the tool.

3

Turn off the ignition, and unplug the tool.

4

Locate the "menu" on the OBD I scan tool, and scroll through it to find the "Stored Engine Codes" command. Select this, and write down the codes that the tool stored. Look up the codes on the scan tools manual.

The Dodge Shadow was a compact car manufactured by Chrysler Corporation from 1987 to 1994. The 1994 version had a 4-cylinder 2.2-liter engine with throttle body injection. This early form of fuel injection used a relatively low fuel pressure of 15 pounds per square inch. The fuel pump in the 1994 Dodge Shadow is attached to the fuel tank, so the majority of the work in the installation of a fuel pump involves the removal of the fuel tank.

Instructions

1

Remove the filler cap for the fuel tank to relieve the pressure in the fuel system. Disconnect the cable for the negative battery terminal with a socket wrench to avoid unintentionally starting the engine.

2

Loosen the lug nuts on the right rear wheel with a socket wrench. Raise and support the the vehicle on jack stands. Remove the cap from the drain tube on the rear of the fuel tank and connect a siphon hose to the drain tube. Drain the fuel from the fuel tank into a gasoline container. Remove the filler tube for the fuel tank with a socket wrench. Remove the right rear wheel.

3

Detach the electrical wiring for the fuel pump and fuel sending unit. Disconnect the fuel lines for the fuel tank and support the fuel tank with a transmission jack. Loosen the mounting straps for the fuel tank and lower the fuel tank slightly with the transmission jack. Disconnect the hose on the pressure relief valve and remove the filler tube from the fuel tank. Remove the mounting straps for the fuel tank and lower the fuel tank with the transmission jack.

4

Release the quick-connect fittings for the fuel lines of the fuel sender unit and disconnect the fuel lines. Remove the mounting bolts for the fuel sender unit with a socket wrench and pull the fuel sender unit from the fuel tank. Detach the electrical wiring from the fuel pump.

5

Remove the nut for the lower support bracket of the fuel pump. Disconnect the lower support bracket and gasket for the fuel pump. Release the clamp for the inlet hose of the fuel pump and detach the hose. Detach the fuel pump from the fuel sender unit.

6

Install the new fuel pump by reversing Steps 2 to 5. Fill the fuel tank and connect the cable to the batterys negative terminal with a socket wrench. Start the engine and check for fuel leaks.
