Question about 1996 Chevrolet Blazer

96 Blazer stalls when hot on hotest days

My 96 Chevy Blazer (172 000 miles) has been stalling for two summers during the hottest days (above 90) and generally after driving 10 miles in the late afternoon (returning home from work). Furthermore it usually(but not always) stalls after slowing down and making a right hand turn and feeding gas to go up a slight grade in my subdivision. It never stalls in the morning.

    I have a 96 blazer about 160,000 that stalls after about 4 hours using when it gets hot is stalls sooner. Fuel pump replace, they tried the computer, Any solutions??? I am without a vehicle right now because I cannot even go to work with a stalling calling the tow truck constantly. IT starts after it sits awhile but if it is hot out it restalls. Any answers or suggestions would be a great help. everyone is stumped right now even the chevy dealer here.

I had a similar problem on my 95 jimmy. It was something that took a lot of time and money to diagnose, but now 3 years proplems. Emissions requires the truck to have an EGR valve (exhaust gas recycle) and this deposits gunk (carbon residue) on your MAF (mass air flow sensor) If you catch it in time you can use a carbon cleaner from Autozone or checker Lightly on the MassAirFlow sensor. If not in time you may have to have either the MAF or EGR valve replaced and these are expensive. After a long period of time being undetected eventually the EGR valve will start smelling like sulfer, this means its to late to clean and save!

Hope this helps

Could be something as simple as a dirty fuel filter.
Get a can of quick start at the store and have someone start it up, when it wants to die squirt a shot into the intake ... if it runs again for a bit you have a fuel delivery issue. Check the fuel pressure to see if the pump is functioning properly.

Why does the car stall in my 1996 s10 chevy blazer while running?

A car stalls when the engine receives a sudden massive increase in load (think when you were learning to drive - releasing the clutch too quickly would cause the car to stall by transferring too much friction too quickly from the gearbox to the engine)
If the car only stalls when you are setting out from stationary then better engine/clutch control control is needed, or there is a problem with fuel or clutch. If it is an old car, try putting more choke on when pulling away.
If the car stalls all the time, the general reason is that there is probably either a fuel or an ignition problem causing the engine to cut out. Of course, there could be any number of things wrong with your car if it stalls during normal driving

96 Benz ran out of gas other day, got it filled up & drove home (20 miles). Next day drove about 40 miles, left car running in park for about 15 min, when I left car was stalling like it was running o

You never leave a car running, as it will
overheat the Exhaust Converter
When you run out of fuel, you sometimes
ruin the Fuel Pump
It depends on gas to lubricate it,as strange as it sounds
Check fuel pressure & volume at the motor with a gauge

Hi I have Chevy cavalier 1995 it was running OK in the summer now when the cold siesan started when I live it for while or over night it takes me while to start it, what may cos that? thank you.

try by changing the coolant temperature sensor, this may be your problem. Coolant sensor problems will manifest themselves during cold starts and during the warm up period, such as hard starting, erratic idle, smoke, stalling, etc, good-day !

I have a 2001 Chevy Blazer, My problem is ,,in the summer time ,it will stall going down the road,,it will start right back up and run fine for a few minutes then quits again. The hotter the day the more...

you may need all new plugs and wires. Now if you said you had a hard time starting it, i'd say be ready to replace the fuel pump, mine just went out last year at 90k. i have an 02.
