You most likely have a bad fuel pump. Very common symptoms your describing, If your handy try squirting some brake cleaner into the throttle body when this happens. If it starts you now know what to do. Also be sure the battery terminals are clean. Voltage drops can cause a fuel pump not to run or run ineffeciently.

93 altima same fuel injector goes bad 2 times in 1 month


how did you find out it is the injector causing the problem? the injectors are wired in series on these vehicles, it is possible that another faulty injector may be causing the problem. although it may be difficult to find if this happens intermittently. A scope test may be the only way to find the problem. Does the engine light come on with a misfire code on Cylinder #1? P0301 or r u just getting a random misfire code P0300 ? a bit more info on the vehicle may also be helpful........ engine size? # of cylinders 4 or 6 ?

2002 Malibu stalls while driving, doesn't over heat. But can start smelling gas fumes before it stalls. usually wait about 5 mins then restarts. in higher elevation runs fine but in lower elevatio


It sounds like the catalytic converter could possibly be almost completely plugged up not allowing the exhaust to leave the engine like it should. It just builds up in the cylinder head and when it gets too much in it built up and there's no where to go, it'll stall the engine. By letting it sit for a few minutes, it gives the exhaust time to find a way out and the car will restart.

Fuel or spark issue???


There is a small relay about $2.00 under the dash that can be fixed real easy. I had the same thing on a Buick I had but I guess they all have the relay.It looks like a fine wire with a very small colored ball in center. I monkeyed around with mine for over a year before one smart guy showed me were it was and how to fix. Good luck hope this helps

Overheats. runs fine when idiling.holding the fan off, and a/c on still cant make it overheat but once driving for 5 mins starts to overheat. replaced thermostat, water pump looks to be fine. cleaned rad....


Water pump. The impeller will slip on the shaft. As you said runs fine at idle, but when you run it harder the impeller doesn't spin fast enough (slips). Causing it to over heat. replaced to many for this problem. Also The pumps that have the metal impellers will be tight when cold, don't let this fool you. when they heat up they slip.

After driving car for one houe, making two stops, shutting off engine and starting it up again (no problems), returning home, parking car and shutting off engine. Went back to start car less than 5 min....


You say it started up no problems? Then it wouldn't start? What did it do when it wouldn't start? Did it turn over, did it do nothing/something?
From just what little info I have I tend to think it's a starter. It starts fine when it's cold but after the engine heats the starter to engine operating temperature the starter maybe starts to drag? not allowing it spin the engine fast enough to start it???
This is only a guess with the limited info. Hope this helped thanks, HAVE A SAFE AND PRODUCTIVE DAY!

Thermostate ranges from overheating to just fine while driving.


is the fan working? if the fan isnt working it will overheat when idling, as it wont be sucking cold air through the radiator. a quick way to diagnose that your cooling system is fine is when stuck in traffic, turn your heaters onto hot, if the engine temp gauge shows that the engine is cooling down, the cooling system will be fine 9/10 times.

hope this helps.
