My 95 Chevy blazer will only start if I prime it with gas. It will only crank with out priming, like it isn't getting fuel. Fuel pump is running, I can heat it turn on. What could be causing this no-start condition? Please advise. Thanks
You may have a leaky injector or a faulty fuel pressure regulator. Sounds like the pressure is bleeding off at start up. Try cycling the key 3 or 4 times before you actually crank it. See if you can get some pressure built up. You will have to get a pressure tester hooked up and see if it's bleeding off.
Not getting enough fuel to the engine. Check the filter. You know it's nothing electrical cause you can get it to crank on. If I were you and drop the tank and check the fuel pump window vent valve if the vent valve is broken then replace it it's really cheap but it's the fuel pump isn't working then obviously replace that as well and get the pressure tester after that and then see if it's pushing enough and if it's not then not too sure
