Question about 2000 Chevrolet Silverado 1500

1 Answer

I ran out of gas on my chevy silverado 1500 v6 and tried to restart it, and burned out my fuel pump. I replaced my fuel pump but it still won't start. I tested it, and gas is getting up to the point where it would be distributed to my injectors, but gas is not being injected on to my spark plugs. I also borrowed a scanner and when I plugged it in to the computer it said a bad ignition module. Could that be the problem? It keeps rotating but won't start.

    Ya, it wouldn't have burned the fuel pump out but like an idiot I tried to restart it. So I replaced it, and I also have a chilton book that I was able to reference for the code. I replaced the ignition module and the truck started. The only problem now is that my truck feels like it is lacking in power. A couple of other codes it threw out was a few bad upstream oxygen sensors. Would that limit the fuel being sent to the fuel injectors?

I doubt running out of gas burned up the pump. A scanner doesnt say anything, it puts out a trouble code, what is the code. do you have spark at the spark plugs? if not check the Crankshaft position sensor. What is the fuel pressure?

    Well...you need to start with the most obvious ,and thats getting the oxygen sensor reading right. Was the code for BAD sensors or LEAN, if lean you really need to check fuel pressure. If they are bad, replace them, but it should run OK cold until the sensors get hot enough for "closed loop" they have heaters in then to speed up the process. But start with the Oxygen sensor problem first, you have to start somewhere.

Well it could be numerous if things but you want suggestions...So here's mine..Your gas tank might be vapor locked...This is caused from over filling your gas tank with gas over the years..Its when the pressure in your gas tank becomes greater than your fuel pump. It wont start until the pressure in your gas tank becomes lower then you fuel pump...Sounds crazy...This got me once...I didn't understand it...A lot of people (including me) Go to the gas station and get that extra 50 cent after the gas nozzle clicks off...over time that extra gas will run down the vapor lines intended to burn fumes....Like when you fill a gas can to cut your grass...If you sake the gas can it builds pressure and bows up. But with time that pressure will go away...Well saying that...Your gas tank needs to vent to....So your car burns not only gas but fumes...If you keep over filling your car with the extra gas it cloggs up your vapor canister intended for fumes or vapors...The gas will will go into that canister and clogg up the charcoal that's inside it. (Breaks it down) then the vapors can't get to your carburetor where it supposed to burns it. So what happens is the pressure in the gas tank becomes greater than your fuel pump and then car won't start..Are you with me? Lol Its crazy..Putting a different gas cap can cause the same thing...Simple test...When you open your gas cap to get gas.. Do you heat air sucking in.. Yes you can hear it....A lot of times loosening the cap let's the pressure out and the car will start right up.....Thus might not be your problem but worth telling at the gas pumps to other people..... Just trying to help

1999 chevy silverado ran out of gas


After you have the battery charged, you may want to check the fuel pump relay and see if the pump is getting power.
Its possible the pump is cooked from not having gas in the tank.
The liquid gas cools and lubes the electric pump.

I ran ouy of gas in 1999 chevy i put gas back in it and know it won't start


You may have siezed the fuel pump. Fuel is used as a lubricant for the fuel pump. When you run out of gas and continue to crank the engine the fuel pump siezes from lack of lubrication. Sometimes you can get lucky by banging on the fuel tank while someone else turns the key to the run position (Not cranking the engine). keep slapping your hand against the fuel tank. This may free up the fuel pump. when you hear the fuel pump hum again then all is good. Also check your fuses, maybe you jsut burned up the fuel pump fuse.

Having problems with 2002 chevy silverado 1500 won't stay running. cut out going down hiway then died will run a while then die is this the fuel pump


Start with the simple and replace the fuel filter first. If it was the fuel pump, and being electric. It would have not restarted again if the pump has gone bad. The fuel filter should be replaced every 1,500 miles or once a year to ensure that your fuel system is running 100% and will not burn out your fuel pump early due to extra heat generated from working harder then is should. Good luck and keep me posted.

Chevy Trucks, Blazers, S10 pickup and the like will vapor lock ecspecially the 2000 models. Do not tighten the gas cap past 1 click. There is a tube that runs from the top of the tank down and this gets hot and collapses or burns in half. We just bought a reinforced rubber tube cut it to lengh and use it instead of part and it's worked grat for 2 years so far.
