What is the fuel pump pressure for a 2001 chevrolet blazer 4.3

Well the fix to my problem was actually pretty simple. Unlike most vehicles this Chevy uses a different type of fuel injection system. This fuel system requires the proper fuel pressure. Without the proper fuel pressure the injectors simply don't open at all. So my pressure was a little low and at times would drop a little too low and the injectors would not pass any fuel at all therefore the engine completely cut out. Replacing my leaky fuel pressure regulator followed by replacing my low pressure fuel pump fixed my problem. there is also a conversion kit where you can convert to a regular injection system that will continue to work even when fuel pressure drops below the threshold. Your fuel trim will be wrong and it will lose power but it will still run at least.
