Hey all. I'm having a problem with my Blazer. I filled up at the gas pump last week. When I got back in to leave, it would not start. A couple times in the past, it has done this but it would start after a few minutes. Not this time. I left it at the station overnight. It started and ran for about 30 seconds and stalled. I disconnected the fuel filter on the engine side and got no flow out of the end. I took the filter off and got a stream of fuel out of the line. At this point, I figured the filter was the problem. I replaced it and it still wont start. I disconnected the filter again on the engine side and let the fuel run out of the line. I reconnected it again and and it ran for about 10 seconds. I pushed the valve in the fuel line under the hood and it had pressure. I ran the gas out of the intake line once more. Now the line is not filling back up and I get nothing when I push in the test valve. Any help on this topic would be much appreciated. Thanks

I have a generic psi and vacuum tester. The fuel pressure test port has a schrader valve.
Anybody know what size that is and where I can get an adapter to fit the hose on my tester?
