Will turn over but will not start
it indicates that the alternator is not functioning sufficiently to keep the battery charged.
Could be a battery problem, discharged, dead or dirty/loose battery connections.
Low battery, bad connection or starter.
Low battery and when attempting to start car ran battery further down. Date and time went to default settings and fuel gauge registered empty. Charged battery. Fuel gauge still showing nothing. Picked up answer from Audiworld post. Removed fuse 15 (instrument cluster) & 28 (fuel pump), turned on ignition or to start the car - might not start, but mine did), put fuses back in. Fuel gauge now correct.
Based on the The ones I have seen, make sure the battery is charged, and the off/on switch is functioning. David
Low voltage from the battery, can be caused by a faulty battery or an alternator that isn't functioning properly. Bad starter Corroded battery connections or other electrical connections.
Sounds like the charging system has failed. Have the system tested by your local auto parts store, they will do this for no cost.
Typically that means that the alternator is not functioning properly and is unable to maintain the battery charge. Many auto parts retailers will test the charging system for you, free of charge. If the battery light is on, have the charging system tested immediately, before your battery goes dead and you are unable to start the car.
Because the engine isn't functioning properly. maybe you have a battery leak. maybe your electrical wiring of the car is old, fried or damaged. Most obvious is a weak battery. How old is battery? Corroded battery terminals are also a suspect
Because you are asking the battery for its full power available to crank the car's engine over. It could also mean the battery is weakened or weakening and requires replacement or perhaps recharging. Almost all the energy available is going to the start function.
clean battery terminals and replace cable ends, check also that the fuse from the alternator is not blown. The car needs min of 12 volts to start or it will just sit there and click Check the voltage gauge when you turn the ignition on if it is low it will not start
The battery is basicly used just to start your vehicle, the alternator is what generates your power once the vehicle is running. Which indicates you need a new battery, not an alternator. That is why you problem goes away after a jump start(boost). If it was the alternator the problem would not go away and your vehicle would have no lights and stall with no start. Either your battery is bad or the alternator is not charging.
