1998 Chevrolet Blazer, 4 door, 133,000 miles. While driving at about 40 mph, the accelorater quit working, and then the vehicle died a few seconds later still in drive. I pulled off the road and tried starting it because this has happened before. The vehicle would try to crank, but would not start. I had it towed to my house and tried to start it a few hours later, but it still would not turn over. My friend and his dad have replaced the fuel filter, the battery, the starter, and I have had the temp gauge replaced. I also had the alternater checked, and its fine. People are telling me that it is the fuel pump/injectors. I figure thats all it could be as well. Please help.
Its possible it could be a fuel pump. Try this. May need another person. Go under the truck right under the fuel tank and have someone turn the key to the on position but do not start the truck. See if you can hear the fuel pumpmcome on. May have to do this several times. Or try this. Look under the hood for the fuel line that goes into the engine. What you are looking for is a Schrader valve. It looks like the stem on your tire where you put air in. It may have a cap on it. Get something to press the little valve, and have someone turn the key. Be VERY careful, as raw fuel will spray out. If the fuel pump is working, then you'll get a noticeable spray. If not, there will be no fuel pressure.
