Hello all, I have a 2002 chevy blazer ZR2. The problem i am having is that the engine won't stay running. I had the battery checked and it is fine, I changed out my thermostat because it was bad. I will start it and it will run for about 20 seconds and shuts down. Is it possible it may be the fuel pump? It shuts down and won't restart. I can't think of anything else except fuses. Any help will be appreciated. thanks Scott in ct

 

Put a fuel pressure gauge on it and watch it while it is running and when you try to restart it. A fuse has nothing to do with it if a fuse was bad it would not start at all.
