SOURCE: 1999 Chevrolet Silverado 1500 Fuel Pump

check the connector to the fuel pump for corrosion or loose pins, the fuel pumps of newer cars and trucks are designed to last at least 100,000 miles, when the new pumps quit did u verify they had power to them?

SOURCE: where is the fuel pump shutoff switch located on a 1996 chevy silverado 1500 located

Should be on the passenger side kickplate below the glovebox and to the right. You may have to remove the plastic panel to access it or look for a small hole in it and feel around for the button

SOUNDS LIKE A POWER STEERING PUMP NOISE, IF THAT IS NOT IT THEN IT IS THE FRONT PRESSURE PUMP IN THE TRANSMISSION.

2000 Silverado 1400 with new alternator. Squeaking when accelerate and decelerate. Goes away at 10-15 mph. Could it be something was not tightened with new alternator?


You may have a problem with the belt tenisiner they do ware out .But first try this take a bare of soup and with the engine running touch it to the side of the belt a lot of times this will stop the squeaking and olny takes a munite .But also check to see if the belt is running true and its not wobbleing from side to side if it is then its a n alignment issue witch means the pulleys are not lining up correctly

2005 silverado z71 5.3. Under normal acceleration all lights will pulse rapidly (at least once a second or faster). Checked alt output at idle- 15.3/15.5 Didnt have a second person to throttle it to check...


Yes,it is,the alternator is charging to much,this can lead to other component failures.Have the alternator changed,not just the regulator in the alternator,if a diode has burned threw,it can,and most likely is,putting out some ac voltage,witch is very bad for the ignition system,and it will put ac voltage in the battery.The pulsing is from ac voltage,not just a dc overcharge.The alternator should be 13.65 volts,to 14.25 volts,at the battery.Most of the time,when there is a pulse,in the lighting,and the alternator is charging around 15 volts,there is ac volts present.so this means,the battery would need to be changed also,to prevent any other problems.I hope this was helpful,and if so,please let us know,thank you.

How do you get the alternator back on 2003 2500


The belt tension is automatically adjusted with the tennsioner pulley. As far as putting it back on, I am not sure what you mean, you just need to bolt it back up and pull the belt over the pulley.

Engine whines when put into gear. When you take


Sounds like you have a planetary gear whine. This is internal to the transmission and only engages when in gear. The only correction is t minimul, a soft rebuild of the transmission.
