'90 240DL - runs for a few seconds, dies

[Mark Price]

Our 1990 240DL's engine problem has gotten worse. Previously, it was
running lean and hesitating. Check engine light came on, the codes
that it gave indicated a lean condition. After driving it awhile
longer, it is now at the point that when starting it up, it will run
for 2-3 seconds and then die. It will start right up again, but only
running a few seconds before dying. I have replaced both fuel pumps
and fuel filter. I tried unplugging the hose on the fuel pressure
regulator. What else should I check?

thanks
