Good tip on the smog pump.


As to your fuel pump issue, first check with a meter to make sure that you've got voltage to the pump when ignition is in the ON position.

Then, there's a terminal you can jump with a wire (I forget offhand, but it's posted here many times) to force the pump on. Then you can narrow down between bad fuel computer and bad fuel pump. I think the fuel pump relay is integrated into the fuel computer (EZL?) on these later 300SE models.
