Iwas the air filter piping removed ?- loose piping or unplugged sensor in plastic pipe could cause problem - water pump is on other end of motor - was air bled from water system - bleed screw on thermostat housing

My floater in my fuel pump was not working , also it would stall on me , so I changed it , but I didnt changed the fuel filter and its doing the same thing

Stall at highers speeds, yes the fuel filter. I replace them with every pump. Parts stores don't warranty the pump without a new filter. If it stalls at idle, then the air filter, vacuum lines, clean the throttle body and idle air control motor.

I have a 1994 k1500 silverado with 5.7L engine. Its been stalling, so I replaced fuel pump, but It is still stalling out on me, do I need to replace the fuel sending unit also?

the fuel sender unit
is for the gauge to read quantity in tank and is usually incorperated in the pump unit ,when it stalls does it start straight away again ?its more likely to be related to air/fuel , spark ,vacuum at the engine so i'd do a few basic checks there ie air intake pipe not collapsing , air filter ,plugs , vacuum pipes etc are in good condition , also fuel pump relay may be breaking down , as you see there are a few things it could be , the OBD may give you a clue so have that read but pre1996 vehicles this was pretty basic and would need a mechanic with the right reader to do this or log onto a chevvy forum as these places are full of knowledge specific to chevvy, good luck

1995 Buick Century. Engine stalls after ~5 minutes when started warm. Engine runs rough for a few seconds before stalling. Happens even at highway cruising speed. Will crank and fire and stall when you...

Using excessive fuel cleaner can damage injectors and the fuel pump - sounds like your problem is the fuel pump bearings, and you will probably have to have it replaced.

2005Chevy Equinox. Installed new fuel pump, still stalls after 15 sec.

Try changing your fuel filter and PVC Valve. Sounds like a vacuum leak or moisture problem. Does it happen only when it rains or snows? Do you use fuel injection cleaner regularly> Try some dry gas. 2 bottles to a full tank, if moisture it could help. Might be bad gas. Next solution is Oxygen sensor. Check hoses to make sure they are on tight and have no cracks. If hoses are hard, dry & brittle they may have cracks you can't see and that will cause a vacuum problem. Could be a problem with EGR Valve. Check all connections and hoses. Replace Air cleaner filter and make sure there are no mice or squirrels living in motor compartment. Could block air intake and stall motor. Good Luck!

1989 S-10 started running rough, now it's not running at all.

WOW ! believe it or not you did good ! what else could it be ? does this engine have a MAS, mass air flow sensor ? sell your scanner or take it back for refund, buy a new MAS, if your engine has one, and replace your air cleaner if you haven't. this part is a major player, if you have one, make sure its an OEM replacement part, not after market ! have you checked all your VACUUM LINES, is this an automatic ? anther thing, now that I'm thinking, what kind of COIL do you have ? I would suspect your coil and all that relates to the coil ! DO THIS FIRST ! before anything else. then more on, but I have a idea that this is it, go for it, when coils get too hot they tend to go bad, how are your spark plug wires ?

Engine stalls. Will start but engine runs for only a few minutes then stalls. Could it be a clogged fuel filter? Assuming it is the fuel system.

If it's running for a few minutes, it is likely the filter. If it's a few seconds, it will be the MAF. Mass air flow sensor.

Overheating engine that runs very rough

Your mechanics are worthless, trying to charge you for **** you don't need. Water pump or thermostat is possible. No. If it started blowing cold that means that either you were completely out of water, or that there is a stop in the water passage way somewhere. A sticking thermostat could be it, and maybe the water pump might be going out, doubtful tho if it works sometimes. I would replace the thermostat and see if that fixes the over heating problem.

Another thing, is the timing of the motor. That will cause it to stall at a low rpm and run rough, and also can cause over heating due to it detonating. Buy/rent/borrow a timing light and hook it up to the number one cylinder spark plug wire and shine the light at the harmonic balancer on the crank and check for timing. There should be lines on the crank and the block that line up if it's timed correctly. And the air pump shouldn't be bad or need a belt (if it's still spinning) but pull a vaccum test on the motor to see what the vacuum is at. Hopefully, this has helped you. Buying a repair manual at you local auto store should help you with changing your thermostat, timing, and vacuum test as well as what the vacuum of the motor should be.

Engine problem.

Hi Michael,

The motor shut off and the engine light came on, you won’t start right away and you wait a couple of days and start it again, sounds like your engine was over heated and because it is too hot and the engine frozen.

There are several kinds of engines, water cooling ,oil cooling and air cooling.

Over heated can cause many different problems for the cars, you should check step by step yourself.

Water cooling engine; if you know, you can help somebody.

1. Check the radiator see if you have enough coolant
2. Check the oil see if you have enough oil
3. check the water pump see if the water pump works fine
4. check the thermostat see it is function right.

Suppose your radiator has water or coolant, leave your radiator cap open, start your engine, let it is running 10 to 15 minutes and wait it is getting hot and see the water in your radiator, if the water moves, that means your cooling system works fine, otherwise either the thermostat frozen or the water pump was broken.

You mentioned when you re-start your car, sounds like a diesel engine, please check the where the noise from, if the noise from the water pump area, that means you need to change the water pump. When you change the water pump, change the thermostat at the same time, because when the engine over heated, the thermostat maybe damaged.

Oil cooling engine, check the oil pump. If the noise from the oil pump, you need change it.

Good luck,
