Yes, the battery must have some 'juice' in order to run the fuel pump. I left my running lights on one day and the batery was completly discharged. I tried roll starting the car to no avail. When I got a jump start, it started (jumper cables connected) after giving it a few minutes to charge my battery. Upon disconnecting the jumper cables, the engine immediately quit. I had to leave the jumper cables connected for about 5-10 minutes in order to have enough power in the battery. I also had one of those 'weak' regulators in the alternator that produced only about 13.5 volts. This is sometimes a problem with the bosch alterators. Worn brushes will also cause low power even though the 'idiot' light does not come on. Fortunetly you can buy new brushes (and complete regulator kits) that can be installed without removing the alternator. Jim '87 C900 247K miles
