fuel pump??

i am thinking my fuel pump went out? I started the truck after about 10 seconds then the "oil pressure low" warning light went on, truck died and now it will not start. Usually when you turn the key you can hear the whine of the fuel pump, but now, it does not do anything.

there is plenty of oil in the engine, and the "low fuel" warning light is now on and and fuel gage does not register any fuel and i know its full.

any suggestions are greatly appreciated, oh and i just turn 100,000 miles on an '01 if that helps

Try searching the Tahoe and Suburban site. Theirs lots of talk on fuel pumps, fuel filters and fuses and that might help you. Dave

I have ggod news and bad news. The good news,I know what the problem is. The bad, it is expensive. This is a common problem. Chevy switched from a float style fuel guage to an electronic sensor. Now the fuel that the US has been shipping in lately has a higher than usual sulfur percentage. The sulfur is eating away at the sensor causing eratic guage readings. This peice can not be replaced alone. You must drop the fuel tank and replace the whole unit. The other problem is that you will be replacing it with another bad part. Chevy has yet to release the new style pump. If you were under warranty is would be covered. If you only had the eratic guage you might be able to live with and track you fuel with your odometer but it sounds like you need the whole new unit. If you take it to a dealer tell them you know this is a commoon problem and that you know there is no perminant fix yet and they may drop the labor rate a little for you. Good Luck

You say it's the fuel pump, but I have experienced the erradic fuel readings wihtout it impacting the ability to start my truck. That sensor was replaced a year ago.

I also had a recent experience where my Tahoe would not start the other day. It was on a steep incline. I knew I was low on gas and wondered if the fuel intake was on the rear side of the vehicle, as I was pointing head-first down hill. Once a tow truck got me on level ground, the Tahoe started like a charm and read 1/8 of a tank (I've ran it far below E before. However, I also noticed that the security light was on after I started the car. Is the security system somehow tied into whether a car will start (some sort of theft deterrant if towed)? Where is the fuel intake on that tank itself? I would appreciate your thoughts.

At least you weren't driving like I was when it died! I was driving and the vehicle completely died. My steering column locked and it wouldn't turn over. The dealer replaced the fuel pump and I was informed that it was a common problem. My pump went out about 65K miles. The car was so dead I couldn't even reset the door locks.

I was researching fuel pump problem at the library which has full GM shop manuals on my 1997 Tahoe 5.7l.

There was some mention about the oil pressure switch being a backup for a failed pump relay (located in under hood fuse box).

As I recall it acts as bypass when oil pressure is 4 psi or greater.

Of course this assumes engine is running in the first place.
