How to Install a Fuel Pump Module on a 98 S 10

The Chevrolet S-10 is a compact pickup truck that General Motors manufactured from 1982 to 2004 in the United States. It had a 6-cylinder 4.3-liter engine with sequential fuel injection, which requires a high-pressure electric fuel pump. The fuel pump in a 1998 Chevrolet S-10 is attached to the fuel tank. This requires you to remove the fuel tank before you can install the fuel pump.

Instructions

Disconnect the cable from the batterys negative terminal with a socket wrench to prevent starting the engine accidentally. Open the fuel tanks filler cap to relieve the pressure in the fuel tank.

Siphon the fuel through the filler tube with a hose and drain the fuel into a gasoline container. Raise the rear of the truck with a jack and support it on jack stands. Remove the plastic tank from the fuel tank with a socket wrench. Release the clamp for the fuel tanks filler hose and disconnect the filler hose.

Disconnect the electrical wiring and fuel lines from the fuel tank. Support the fuel tank with a floor jack and remove the fuel tank straps with a socket wrench. Lower the fuel tank slightly with the floor jack. Detach the electrical connections and fuel lines from the fuel sending unit. Lower the fuel tank completely with the floor jack and move it to your work area.

Turn the locking ring for the fuel sending unit counterclockwise with tool No. J-24187. Remove the locking ring from the fuel sending unit and lift the fuel sending unit out of the fuel tank. Discard the O-ring for the fuel sender unit. Pull the fuel pump into the mounting tube as you pull it away from the bottom support. Pull the fuel pump out of the rubber connector once it clears the bottom support.

Install the new fuel pump and O-ring by performing steps one through four in reverse order. Start the engine and check for fuel leaks.

How to Find an F150 Airbag Control Module

A Ford F150s air bag control module is in the trucks Supplemental Restraint Systems central computer. The module governs all the air bags within the truck, and it also interacts with the system for signs of problems. If a problem is sensed with any of the air bags, the SRS warning light will activate on the F150s dashboard. Locating the module is fairly simple; however, the SRS system is complex and most repairs should be deferred to a trained professional.

Instructions

Ensure the Ford F150 is completely off. Pop the hood and remove the negative cable from the negative post on the F150s battery. Wait five minutes, so that any remaining power within the truck drains out. This is an absolutely necessary precaution. Anytime you work in the vicinity of the dashboard or any air bag components, the SRS system must be disabled. This will keep the air bags from accidental deployment.

Open the passenger-side door and locate the right kick panel. It will be the the right side of the passengers side leg-space.

Loosen the right kick panel. Depending on the model and year of F150 truck, you should be able to pry it off with a trim tab or a flat head screwdriver wrapped in tape. There may be retaining clips behind the panel. In order to avoid any damage to the panel, lever it off slowly. If you meet any signs of resistance, stop and investigate the obstruction.

Remove the right kick panel. The air bag control modue will be behind it.

How to Replace a BMW 330I ECM Module

The BMW 330i is a compact executive car that was in production from 2000 to 2007. It had nn anti-lock braking system, or ABS, as a standard feature. The ABS had an electronic brake control module, or EBCM, that controlled the hydraulic pressure to each brake caliper. This gave the car improved braking. The procedure for replacing the EBCM is generally the same for all versions of the BMW 330i.

Instructions

Remove the cable from the negative terminal of the battery with a socket wrench. This prevents anyone from starting the engine during the EBCM replacement procedure.

Remove the cover for the hydraulic control unit, or HCU, on the right side of the engine compartment. The HCU is a cube-shaped component with hydraulic brake lines connected to it. The EBCM is a smaller, narrow component on top of the HCU.

Release the clamp on the EBCM. Pull off the right side of the multiple plug from the EBCM, and disconnect the left side of the plug from the EBCM. Disconnect the mounting bolts from the EBCM with a socket wrench, and remove the EBCM from the vehicle.

Install the new EBCM to the HCU, and fasten the mounting bolts for the EBCM with a socket wrench. Connect both halves of the multiple plug to the EBCM.

Attach the clamp on the EBCM, and replace the cover for the HCU. Attach the cable for the negative battery terminal with a socket wrench.
