How to Replace the Fuel Pump in a 97 Lumina Car
The Chevrolet Lumina is a series of coupes, minivans and sedans manufactured from 1990 to 2001. The replacement fuel pump for these vehicles depends on the engine, which may be a six-cylinder 3.4 L engine or a 3.1 L engine. All versions of the 1997 Lumina have sequential fuel injection, meaning that the electric fuel pump on these vehicles uses high pressure to deliver fuel to the fuel injectors. You can access the fuel pump on most 1997 Luminas through a removable access panel in the trunk.

Disconnect the negative battery cable with a socket wrench, and remove the engine cover. Relieve the pressure in the fuel tank by loosening the filler cap for the fuel tank. Remove the cap for the fuel pressure port on the fuel rail, and connect special tool J 34730-1A to the fuel pressure port. Place the bleed hose for this special tool into a gasoline container. Open the valve on the special tool to bleed the fuel in the fuel system into the gasoline container.
2Drain the fuel tank to 1/4 of its capacity, and remove the jack, spare tire and spare tire cover from the trunk. Take out the trunk liner, and unfasten the retaining nuts for the access panel with a socket wrench. Remove the panel, and disconnect the electrical connector for the fuel pump.
3Clean the fuel sender assembly with a shop rag, and disconnect the quick-connect fittings from the fuel sender assembly. Remove the retaining snap ring on the fuel sender assembly with a socket wrench, so that the fuel sender assembly springs up. Remove the fuel sender assembly without handling the fuel pipes. Discard the old O-ring and clean the sealing surfaces for the O-ring.
4Place the new O-ring on the fuel tank and install the new fuel sender assembly onto the fuel tank. Avoid folding the fuel strainer and ensure that the fuel strainer does not impede the movement of the float arm for the fuel gauge after the installation is complete.
5Replace the retaining snap ring for the fuel sender assembly, and turn the snap ring clockwise with a socket wrench until it fully seats with the fuel tanks tab slots. Attach the electrical connector and quick-connect fittings to the fuel sender assembly. Connect the cable for the negative terminal on the battery, and fasten the filler cap for the fuel tank.
6Turn the ignition switch for 2 seconds, then turn it off for 10 seconds. Turn the ignition back on and check for leaks in the fuel system. Replace the access cover in the trunk and tighten the retaining nuts to 96 inch-pounds. Replace the trunk liner, jack, spare tire and spare tire cover.

Installing a Fuel Pump on a 97 Chrysler Sebring LXi
Like the first generation of Sebring Convertibles, the 1997 Chrysler Sebring LXI has a Mitsubishi 2.5L V6 engine with fuel injection. The fuel-injection system operates under very high pressure supplied from the gas tank by the fuel pump. Replacing the fuel pump on the LXI is a different procedure than other Sebring models, but fortunately, is well within the capabilities of even a novice mechanic.

Relieve fuel tank pressure by opening the gas filler cap. Inside the car, pull upward on the rear seat cushion to disengage it from its retaining hooks and remove the cushion from the vehicle. Of the two access panels underneath the cushion, remove the one on the right.
2Disconnect the wiring harness that attaches to the fuel pump. Turn the ignition and allow the engine to run until it dies from a lack of fuel system pressure. This permits safe removal of the fuel pump. Once the fuel pressure has been released, disconnect the negative battery cable.
3Remove the hose connecting the fuel pump to the fuel rail. Remove the mounting bolts holding the fuel pump in place and lift the pump out of the fuel tank. Wrap the pump in shop towels to catch remaining gasoline and relocate the pump to a well-ventilated area.any
4Place the new fuel pump into the fuel tank by carefully aligning the pump with the slots in the tank until the pump is securely seated. Reinstall the mounting bolts (22 inch-pounds of torque) and reconnect the hose leading to the fuel rail. Reinstall the access panel and seat cushion.
5Make sure that the gas filler cap has been reinstalled and reconnect the negative battery terminal. Turn the ignition to the "On" position for a few seconds to allow the fuel system to build pressure, then start the engine to confirm proper operation.

How to Reset the Codes for a 97 Mitsubishi Galant Radio
When voltage is interrupted to the radio in a 1997 Mitsubishi Galant, it locks up and prevents the driver from using any of the radio functions. The voltage can be interrupted for a number of reasons, such as a dead battery or disconnecting the battery to perform a repair on another component. In order to get the radio out of its locked state, youll need to enter a correct security code. If you enter an incorrect code more than three times, the radio will freeze for one hour. During this frozen state, it wont accept any additional attempts at inputting a code.
Instructions

Turn the ignition on and sit in the drivers seat. Press the power button on the radio.
2Look down at your security code card. Use numbers 1-4 on the front of the radio faceplate to enter your security code.
3Listen for a beep confirming that your code was accurately entered. If your code was not entered correctly, ERR will display on the radio screen; you will have 2 more attempts to enter the code before the radio freezes.
4Test all functions on the radio to confirm that it works properly.

How to Reset Airbag Lights in 97 Jeep Wranglers
The airbag light, or SRS (Supplemental Restraint System) light, will illuminate on the instrument cluster of your 1997 Jeep Wrangler when there is a malfunction in the airbag system. Have your vehicle towed to your mechanic to have it checked out and repaired before attempting to drive it again, and before you reset the light. Once the issue has been addressed you can reset the light yourself to save time and money. You must purchase a code scanner to get the job done. An auto parts store may let you borrow its scanner for free.
Instructions
- 1
Place the key into the ignition and turn on the vehicle, but dont let the engine turn over.
2Find the diagnostic port under the steering wheel. This port will be the same size and shape as the connective end of your code scanner. Carefully plug the scanner into the diagnostic port, taking care not to force the plug in. If you force it, the pins inside could be damaged. The vehicles battery will power on the scanner.
3Use the arrow keys on the scanners keypad to scroll through the menu options. Find the "delete" or "reset" option and select it. This will turn the SRS light off. Unplug the scanner and turn off the vehicle.
4Wait 60 seconds, then turn the engine on. Observe the instrument cluster to verify that the airbag light is off.
