Diagnosing the Battery, Charging, & Ignition System Many driveability and starting problems that are charging, starting or ignition related may be due to low battery voltage. It's a simple thing to check, yet many technicians overlook the battery as a possible source of trouble. Low battery voltage can also affect fuel delivery by causing the fuel pump to run slower than normal. This, in turn, causes, low fuel pressure and a lean fuel condition. Under some conditions, a low battery may even prevent one or more injectors from opening normally causing lean misfire and/or hard starting. Automotive lead-acid batteries must be kept at or near full charge for optimum performance and longevity.
