Automotive Fuel Problems

FOR IMMEDIATE RELEASE
Lees Summit, Missouri, United States of America (Free-Press-Release.com) February 16, 2012 --

Automotive fuel systems can be a daunting task for the average person but some simple how to info can go a long way to get it fixed the first time. The first thing to check is do you have gas in the tank? If you do you need to check if the pump is working. The easiest way is to have someone cycle the ignition switch on and and take the gas cap off and see if you can hear the pump making noise. Another way is to just get a fuel pressure tester and just screw it on the fuel rail and turn the key on and see what PSI you have. If you have almost no pressure your pump isn’t working but it could still be a relay. Most fuel pumps go out around 100k miles on domestic cars and longer on imports. If you have good fuel pressure your pump is obviously working which means the relay is too so it could be the fuel injector isn’t firing and that usually means its a bad cam and/or crank sensor. Fuel pumps are pretty easy to replace, just drain or siphon the tank then take of the 2 straps holding the tank up while supporting it with a jack. when the tank is empty it doesn’t weigh very much. Lower it down and disconnect the fuel lines, wiring harness, and the filler neck and just lower down and remove. Most pumps are held in the tank with a lock ring just remove the ring and the pump and replace. If you can get to the main plug on the pump without removing the tank you can check for voltage there to see if your getting power to the pump. If there is power at the pump and the pump doesn’t work the pump is bad. Remember fuel is very flammable.
