Any Idea? Not fuel pump?

Question

2001 Chevy Blazer ZR2 . Crank, no start. I have good spark. Fuel pump is working. I have 58 pounds of pressure (constant) at the schraeder valve. But I'm not getting fuel. If I pour it into the intake it will fire up and then of course run itself out of gas, but it wont start or stay running. Oil pressure gauge says its good as well. Any ideas? Thanks in advance.

Do you have a vortec engine? If so a common problem is that the injector assembly needs to replaced-it is located under the intake manifold-have replaced many of these over the years.

Like the other guy said, check your fuel injectors--they could be at fault.  The other thing is to check your fuel filters, especially the one at the throttle body.  If that's clogged, then you won't get any fuel.

nicely in case you are able to no longer purchase the setting up and that's an factor of the pump then you definately will could purchase a pump or walk.There are no rapid fixes while it contains gas line or setting up upkeep until they are changeable.
