You will need a lift or really tall jack stands to do it on the ground, a almost empty gas tank is ideal since your body strength is limited laying on your back with a hard to manage 200 lbs of full gas tank over your face, a pump jack and a 2x4 to put on the pump jack head to help even the load upon removal. Remove the tank straps with the jack in place on the tank and the vehicle in the raised position Once tank is coming down use a flashlight to see the top of the tank At this point there are special tools needed to do the job, spray some wd40 on the connectors both fuel and electrical because the years of road grime have loaded up inside the connectors and this will help aid in the removal . Also on some electrical connectors there are red safety tabs that pull out to allow the connected to be released. You will need fuel disconnect tools, multi color plastic tools in various line sizes to realese the fuel line from the pump one blue one yellow Once lines are off and connectors are off. You l need to remove the fuel inlet hose (where the gas goes in) and the vent to evap canister hose. Now depending on the fuel pump there are a few different styles of pump fasteners, the most common on gm products is the metal ring that you will need a hammer and either a flat head screw driver or long punch tool to release, the wd40 will have soaked into this ring also by now helping you tap the ring off in a counter clockwise motion. Be careful not to drop dirt into the tank, the best thing to do is to blow compressed air over the area to blow the dirt away but some don't have a compressor laying around to do this. Slowly pull out pump and make sure the gas don't pour all over your work area. Inspect the new pump and match them up to be positive the connectors match and that the fuel level sensors are not in a bind and free in motion before reinstallation . My personal opinion is to take it to a shop and save the headache and expense of buying tools you may never use again, but some tools can be rented from auto parts stores. Good luck

Gas guage falls and rises

This problem is causes by a defective fuel level sending unit, The sending unit is located inside the gas tank and the gas tank must be removed from the car and the fuel pump module (contains level sensor) replaced to correct the problem. This job requires a hydraulic floor jack, safety stands to hold the car in the air safely and a very good set of common hand tools plus a special tool to remove the fuel lines from the tank. Time to complete is about 4 hours on the ground.

How to change the02 sensors on a 2003 buick rendevzous

The O2 sensor on your Buick is located on the rear (under windshield cowl side of your exhaust manifold...You might be able to spray injector cleaner on it after removal...use PB Blaster to lubricate before removing the nut...also have you tried running some gas tank fuel injector cleaner in your gas tank recently? Sometimes this will help the sensor to work properly. To clear your "check engine light" you need to disconnect the positive side of your battery cable for about 15 minutes, then reconnect...the light should stay off if all is OK...Hope this helps.

Cruise control keep accelerating when switch was turned off and brake had been applied on 03 buick rondevous

if your cruise control is vacuum controlled then theres a fault with the unit. if its ECM controlled youll have to take it to a dealer/mechanic and have it hooked up to a service computer (not a scan tool)
