Fuel Problem with 2000 Chevy Impala?
I'm having problems with my wife's 2000 Chevy Impala. For a few weeks the car has been sputtering or idling weak, and the other day it finally broke down. The engine will turn over but it dies as soon as it cranks up. Acts like the car is out of gas. However, if I give the car gas while I'm trying to crank it and hold the gas down after it turns over, it will spit and sputter, but stay on for a second.
I left the car alone for a few hours and came back and it cranked right up and I drove it about a mile or two with no problems. It's been driven a couple times since then, and today it broke down again. I replaced the fuel filter on the car. It took me about an hour and a half. I cranked the car up and seemed to be running fine, but it may have just been because it sat for an hour and a half. On the way home, it stalled while I was driving down the road and would not crank back up.
So I've eliminated the filter as the problem, unfortunately. I also checked the air filter to see if I had a problem there and it was fine..
Wondering if there are any other possible solutions. I've read that when the fuel pump is going out, letting it sit for a few hours and cooling down will make it start working again for a while. That is one option. Or, I've also read the fuel pump regulator could be the culprit.
I'm no mechanics, so I don't know a lot about diagnosing these problems. Any help would be great.. Thanks guys.
Plugs and wires were changed about 4 months ago..
No check engine light or anything. Car just acts like it's out of gas. (It's not lol) But it spits and sputters like it is unless I let it sit for an hour or two, and then it runs fine for a while, which is what lead me to believe it was a problem with fuel getting to the engine.
I'm 90% sure it's either the pump or the regulator. Just wondering if there were any other possibilities..

Fuel pumps can create this kind of headache as well as crank/cam sensors. If possible, have the car scanned for history codes to see if something is repeating. If the car runs normally when running, ignore plugs/wires and look at the fuel delivery system. Something you can try is when it will not start, bang hard on the fuel tank. If it starts right up, fuel pump is seizing up when warm.

do u get like a check ingine or service engine soon light in the dash just idling could a sensor like a throttle positioning sensor which detects where position of the throtle or how deep u have the gas pedals down when driving or the idle control sensor which dictates what should be the normal idle rpms it should stay at but fuel pump is a possibility spark plugs not so much

you need to run a test on the fuel pump but before you do that bleed the air out of the fuel lines.when you replaced the fuel filter you got air in the lines and it might be restricting the flow of fuel. you should have a small cap on the fuel rail under the hood.take the cap off, turn the key on and push the valve in it but watch your face.that should take the air out.

Without a diagnostics I'd say change the plugs and wires. The car is 10 years old.
