Could it be the filter or MAP sensor causing a 1992 Blazer with a 350 to keep stalling?
This is something that will drive you nuts. We had one that almost DID drive my friend nuts over. There is no "check engine" light, he replaced everything related to the engine, and it's control devices, and at the end he was ready to start yanking wires. It's symptoms almost mimicked a vacuum leak, but at other times it would run just fine.
Change the fuel filter first. This is the least expensive. If that doesn't correct the problem, and if everything else has been maintained, then I would say replace the map.
What would cause a 96 s10 blazer to be completely gutless i just rebuilt the engine and replaced all o2 sensors map sensor egr valve air filter etc?
I have a 1993 S10 Blazer and I filled up yesterday with 338.2 miles on the last full tank it took 16.258 gallons for a mpg of 20.8, when I first got the blazer a couple of years ago the mileage was terrible, I changed the plugs to Bosch Platinum, changed the oxygen sensor, changed the oil and filter using Castrol Syntec 10 w 30 and changed the air filter. The major causes of my…
The MAP sensor - another frequent cause of stalling or non-starting. This measures the air pressure in the manifold. You can test it - if your car won't start, just unplug the electrical connection from the MAP sensor. If it starts, replace the sensor. MAP sensor details. (It may act as though the fuel pump is not working properly - starting, then quickly dying).
What would cause a car to jerk during acceleration and stall out after you've replaced the muffler temperature coolant sensor and fuel filter?
I had to replace the fuel pump twice. First time the vehicle wouldn't start. Worked like a charm after the replacement, until the fuel gauge sensor failed. Second pump I have put in worked fine until the vehicle started stalling randomly. Kicking the gas tank to start it helped for a while. Checked the ground connection for the pump and it was rusty. Sanded it down with some sand paper, 50000 miles later still working…
