I recently inherited a '78 450sel that had been sitting for a few years. Needless to say the gas was gummy and the car would barely start/run. It had a new Bosch fuel pump put in shortly before it was put away.

Step 1:
* gas tank was drained and put in new gas
* leaking fuel pressure regulator was replaced

That got the car running but it stalls out as I press the gas pedal. If I feather the gas pedal I can get some revs after a while. Pour a little gas into the ventura and it perks up. Once it warms up it idles a little better but but it's still undriveable.

Step 2:
* gas tank was removed and cleaned,
* fuel filter was replaced

Still not running much better - still same symptoms as above.

It has lots of fuel pressure coming out of the pump but it doesn't seem to be reaching the injectors.

Any ideas out there?????
