oil burner running intermittently

Routine fall maintenance changed filter and fuel pump screen. Burner would not fire up getting no fuel out of fuel pump. Installed new fuel pump (2 line system), I Fired up burner ran about a minute and shut down. Blew out line and changed nozzle. Runs but not running strong, seems like it is not getting strong stream of fuel. Open bleeder getting stream but not powerful. There are no air leaks in system. Out of ideas?

Not running strong

I'm not sure I know exactly what you mean by "not running strong". If you have a weak stream from the bleeder, it could be the burner coupling slipping. There could also be some kind of restriction in the fuel line coming from the tank.

Obviously double checking fittings to make sure they are tight. Next when you replaced pump did you put by-pass plug in pump because of 2 pipe system. On a 2 pipe system pump is self bleeding. Put a pressure guage to see what you are running. If you can't get it going try vauum guage to see if oil system is air tight.

Didn't you run the new fuel pump dry after replacement ? :-) Just asking :-)
