Some time when i start my car the engine will make a humming sound. and some time when i am driving the engine will make the same noise.

Turn off the airconditioning to see if that helps. If it does, then it is likely the airconditioning compressor.

Remove the water pump drive belt. Feel the water pump for free play. If excessive, then replace the pump. You can try spinning it too to see if it's noisy.

WIth the drive belts off, start the car for a few seconds. Twenty seconds tops should do it. Not too long as it will overheat.
Is the noise still present. If not, then check all pump bearings, pulley bearings, tensioner bearings, water pump etc as the noise is one of those things.

I was driving my Murano around town delivering papers for 4 hours, I stopped to get my mail, and turned the car off. Got back in and now the car wont start. It will try and be very boggy for about 10 sec....

Let it sit for about 45 minutes before trying to start it again. If after this time, it starts back up, then you are probably having a fuel pump related issue.

Car cranks fine, replaced the fuel relay, camshaft positioning sensor, and a brand new coil and battery. car still turns over perfectly fine, but doesn't start

Turn the key to auxiliry but dont start it. Listen around the feul tak area to hear a humming sound. If you do,then fiel pump is fine. If not then replace fuel pump. If you do,then check timing belt

97 lumina, 3.1. Starts runs smooth, drive for 30

I just recently have been fighting the same problem with the same make/model/year vehicle. For myself, I would drive off and on through the day and it would run fine. Then suddenly after a start it would run rough and die. I would have to wait 20 to 60 mins before it would start again. I had it checked and fuel pump was only putting out around 19 psi. It should be around 41 psi. Had fuel pump replaced and no more problems. Furthermore, now it runs so much better. It's funny how over time I didn't notice how the performance was slowly degrading. Unfortunaley fuel pumps for this car run around $300.

Starts fine & stops in 3-5 minutes or driving in 1-3 miles.

Did you replaced your whole distributor or just the cap and the rotor? Have you check the pressure on you fuel line it could be your fuel pump.

I have a 99 jeep grand cherokee and i put gas in it and drove a 1/2 mile and it stopped accelerating and would not start for 20 minutes now it will start but could this be the fuel pump? All of the...

Cant say if its the fuel pump but how a filter works is when the flow stops the sediment will settle off the filter. If enough sediment is in the filter you will fell power loss after driving for awile.Now if you werent having issues before this doing freeway speeds or gunning it around town I wouldnt suspect a filter from just driving around town. If it were a filter on a vehicle your age it would set a check engine light for running lean,
Now its pretty typical for a fuel pump to stop then work later when it cools off.
If your still experimenting look at the fuel pump realy under the hood in the fuse box and if you have a lookalike like a the horn or ac relay then swith one with the fuel pum relay.
