Question Fuel pump or bad tank of gas?

Didnt realize it was so LONG till I wrote it! SORRY!

OK, Here goes. This is on my '99 LS1 Z28 btw.

I was out running a few errands yesterday and stopped to get some gas because I was near 1/4 tank left and dont like to go below that mark. I put 10 dollars worth of gas(Premium-91)in and went on my way. I ended up drivin about 10-15 miles in stop and go city traffic before heading for the highway to head back home. As I'm waitin at a stop light to turn onto the onramp to get on the highway, I noticed my car idleing a little funny, slightly shaking(best way to describe it) a little bit. Looked at my gauges and all of them were normal. Light turn greens(at this intersection you make a left to get on the onramp) and I gradually go through the intersection making the left turn and punch it to get up to speed. But, as soon as I punched(pedal was damn near on the floor) it my car hesitated a few seconds before responding(It's an A4 so I'm used to some hesitation when I innitially punch it, but not like this), I was like what the ****? I let off the gas and gradually ease into it, gaining speed gradually until I get up to the speed limit(65mph). I set the cruise, continue for a few more miles until my exit is coming up. As I'm approaching my exit, on the right, there is a car I need to pass to get over. I goosed it to gain speed to attempt to pass them, but same hesitation. So I slowed down and got behind them and got over.

A few miles down the road I start hearing a humming/whining coming from the rear of my car but am not sure if its my car or the semi behind me. I assume its the semi behind me and dont pay attention to it. I take my exit and come up on a stop light. As I'm stopped, I open my door and poke my ear out the door and listen, and sure enough it's coming from the rear of my car. Right above my muffler.

I swing by my mechanics shop on the way home and tell him the symptoms and he comes out and listens to it and runs it for codes, but finds none. He says sounds like the fuel pump is going out. Tells me I could also get a new fuel filter to see if that helps with anything. So I go get a new fuel filter and have it put on, and take the long way home to mess with my car/listen to it. I was just cruisin along a few different times at a few different speeds, 35mph, 45mph, and 55mph, and at each one of those speeds I punched it to see the outcome. Everytime I punched it at all three speeds my car threw me back and accelerated like normal. So I'm kind of stumped. It seems like the new fuel filter took care of the 'hesitation' problem, but the humming/whining from the rear is still there. I was also curious, could this be the result of a bad tank of gas and thats it? I am changing gas stations that I go to from now on and half half a tank and want to drive and get rid of the gas to put new gas in, but dont want to take risk of getting stranded somewhere. It starts right up just fine everytime but with my luck....

Anyone else experienced these symptoms?


SORRY SO LONG!


Thanks for replies/suggestions/comments.

No need to apologize for what, in your mind, was a long story. It wasn't. And besides, thats what we're here for!

Reading your post, it seems to me that it may have been a dirty/clogged fuel filter.

That being said, I'd get to a nice, clean, gas station, preferably a Sunoco where you can fill up on 93 octane, and see how the car performs for the rest of this week.

If the "whining" from the rear persists, I'd look into replacing the fuel pump for peace of mind.

I hope that helped?

(PS Don't hesitate to ask questions!)

Thank you for the response. I'm hoping/wanting to lean towards the dirty/clogged fuel filter was the main cause like you mentioned. Basically because of the major price difference between a fuel filter and a fuel pump. lol

I've always got 91 octance(highest octane available in OK, that I know of) gas from QT here, locally. I also didnt realize, until yesterday, that it contained 10% ethenal which is why I assume/hope it was just a bad tank of gas. I'm definiatly not putting anymore of that crap in my car.

The only reason I assume its the fuel pump and not the filter is because it was still whining/humming even after I had a new fuel filter put on.

Your reply did help, as always. Thank you.

Thats what I was afraid of, it ultimately resulting in the fuel pump going out. They're not cheap.

Thank you for the response.

Yea. I called my local Auto Zone, Advanced Auto, and O'Reilys yesterday and between the three stores, prices range from $350-$400.

Wait till see the labor cost.

If it is still humming after changing the filter my guess would be the pump is on it's way out. That's my .02.

I thought about that yesterday after I got the prices from the parts store. But I dont know if I want a used one that will crap out on me(I assume, being used) before a brand new one one.

I was thinking about the labor costs also, as you mentioned. I was also thinking about replacing it myself to save a little bit of money, but that requires removing quite a bit of shit. I know there is a trap door method I could do, but I really dont want to cut into my car even though it wont be visible. So, I donno yet.

It never fails though, when I'm in between jobs as I currently am, something always craps out on my car. But whenever I'm working none of this shit pops up out of the blue. Oh well, nothin I can do but suck it up and get it fixed. Probally be without a car for a week or so in the meantime.

almost all regular gasoline these days has up to 10% ethanol. if you can find a gas station that doesnt have it, be prepared to spend a little more for "pure" gasoline

why run the risks of swapping one from a junk yard that might go out on you the next day?

I dont know where everyone is looking for fuel pumps, but you can get them for right around $100.00 hell, I paid 65 shipped for mine (sale price)

ah.... one for 70.00

the only ones that should cost more than that are the ones that come with a new full wiring harness

There is a gas station right up the road from my house across the street from QT that has gas with no ethanol. Had I known that QT gas has 10% ethanol I would have stopped going there along time ago.

Check out this link to see where everyone is finding fuel pumps for $400. I know you can get just the 'fuel pump' for $100 but why not change the whole assembly if your going to get it done in the first place? Doesnt make sense to keep the 'old' assembly/strainer etc. and replace just the 'pump'.


http://www.autozone.com/R,5332668/ve...ductDetail.htm




*EDIT* My dad just got a quote from our mechanic to have it replaced. $725 for parts+labor.

Looks like I will be driving my g/f's old jeep for awhile. :(




This thread is pretty much dead as far as info I was looking for. Thanks to everyone who chimed in with experiences, suggestions and comments.

Your silly.

They are two totally different parts, obviously.

On one hand, you have your tires/rims which are easily accessible and easy to remove.

On the other hand, you have the fuel pump, which is not nearly as accessible and easy to remove.

For example, lets say I just buy and replace the pump only, but I'm still having issues regarding the same problem. I would be ****ing pissed at myself that I didnt go ahead and get the whole assembly. I dont have the money to just throw around and if this were the case, waste, just to go back in and replace the whole assembly like I should have done in the first place.

Get down and dirty, stick your ear up close to the bottom of the tank...Hear/feel it? Take the cap off, stick a long screwdriver down the hole and put your ear on the end of the screwdriver, what do you hear? Pulling the tank isn't hard, just drain it first Pump replacement is ez too.


Do you have a fuel pressure test gauge? Does the LS1 fuel rail have the fitting like the TPI's did?

I can hear it when I lean down and am back about 2 inches from my gas door. It's like a humming/whinning sound. Hard to tell exactly because of my exhaust how loud it is.

No, I dont have, but need to get a fuel pressure test gauge.

I have no idea regarding your question about the LS1 fuel rail fittings vs the TPI's.

Well, I went to get a couple donuts and took the long way to kind of mess with my car, stop, go, stay at a steady speed, then punch it and see what happens.

First thing I noticed is when I started my car, I did not hear my fuel pump whining/humming. Second, while I was cruising at a steady speed then punching it a few times, it never hesitated. It threw me back in the seat every time. No hesitation whatsoever like it was doing the other day. I'm confused. Is my pump going bad or just a fluke/coincidence that is was making a noise yesterday?

your fuel pump should whine a little regardless.

At this point, just enjoy the car. You changed the filter, and put a tank of fresh gasoline in it, which seems to have it running better. So, IMO, theres no point going ahead and changing the pump at this point.

And like the others have suggested, if you eventually choose to get a new fuel pump, buy new. I only suggested a scrap yard in the chance you found a low mileage, decent Camaro, which met an unfortunate demise.

I did change the filter, as I mentioned.

I still havent put a fresh tank of gas in it. I still have half a tank of gas from the last time I put $10 in it. Don't really have much drivin to do at the moment and don't really feel like driving just to 'waste' gas.

But like you mentioned, I will enjoy my car! I enjoy my car everytime I drive it. How can you not enjoy these cars when you get behind the will?

Did you pull codes? Could be vacuum, EGR, Distributor. Unless your pump fails a pressure test then don't replace it.
