sure could use a little advice here...
I have a 2000 Blazer. My car starts but won't stay running.
I replaced the fuel pump a little over a year ago. Before replacing the fuel pump it wouldn't start, it starts now but just won't stay running

 

Have you tested your fuel pressure again? Is the check engine light on? Codes? Are their any other symptoms? How long will it run for after it starts?

 

No the check engine light is not on. It only runs for a couple of minutes. My brother is gonig to try and work on it this weekend and check the fuel pressure.

 

couple of questions please. We have fuel pressure. Have much fuel pressure are we suppose have? and where is the schrader valur located?

 

The search tool is very helpful...

Fuel pressure test port is located on top of the engine on the main fuel feed line (larger of the two fuel lines).
