Question about 2000 Chevrolet Silverado

1 Answer

Fuel pump? Truck is sometimes slow starting. Gas needle goes to empty and back up again occasionally. Could these both be caused by a bad sending unit plug? Or is it more likely the fuel pump?

    Should the pressure drop after starting the truck? It is 58 lbs when the key is turned, and it drops to about 50 lb when truck starts. Is this normal? If I wait till dinging stops, the truck usually starts fine. If I start it before dinging stops, it starts hard and gives a gas smell and runs like it has too little or too much gas for a minute or so, then it's ok.
    Thanks for any suggestions :>

This sounds very typical of the final days of the fuel pump.

Erratic fuel gauge.


Could be a faulty sending unit in the tank or the gauge on the dash.

Why does my gas gauge needle never go below 3-4 tank?


I would guess the fuel level sending unit is malfunctioning, deposits sometimes build up on the resistor pack, or there is and open circuit in the resister pack, does the fuel gauge needle do a full sweep from empty to full and back when the ignition key is turn to the run position? This is a cluster self check mode, if it fully sweeps than the cluster is ok, I would suspect it needs a fuel level sending unit which is located in the fuel tank as part of the fuel pump modual but usually can be serviced separately

Put in new fuel pump and sending unit. but my gas gauge doesnt always work. sometimes is does and sometimes it doesnt


if it worked for a short period of time after doing the pump/sending unit the check the connections going to the pump/sending unit they would have been moved around doing the pump

Gas gauge goes to empty and then full after fillup


very well sounds like the sending unit in the tank. Try running some octane booster and fuel injection cleaner in tank of the truck to loosen any deposits on the float.

When my 1996 Jimmy gets to a half a tank the gas gauge goes crazy and will go to empty then back to half. I acts like it is running out of gas. It also has a rough idle. What could be causing this...


The wire harness to the fuel pump sending unit may be going bad which is common to happen. The harness is around $15.00 and it runs from the frame to the top of the gas tank. The other thing to is the fuel pump sending unit may be going bad and the float in side that measures the amount of gas, has gone bad and the unit may need to be replaced. As for the rough idle, it cold be related to the fuel pump starting to go bad and the fuel pressure is just marginal to keeping the engine running. The fuel pressure during cold start should be 62-65 PSI and should drop about 5 PSI when the engine is running. The other thing to that would casue a rough idle, would be time for a tune up, "spark plugs, wires and distributor cap and rotor, fuel filter"

2001 chevy silverado 4.8 gas gauge not working properly


Fairly common problem with GM vehicles. The sending unit in your tank has a small circuit board that an arm is attached to which moves up and down according to your fuel level. This circuit board and arm are not making good contact. Unfortunately the only good solution is to replace this part.

Gas gauge stuck on empty


Adam, I like your solution, but this is easier:
1. Get a strong magnet
2. Use the magnet to move the needle into the top half of gage (don't take anything apart)
3. Test it by turning the car on.
