Probably not much because 6 Volts is not enough to power a 12 Volt coil
This type of problem is very hard to find since you can really check it out while it is acting up.Clean the batery cables amd clean and tighten all of the ground wires you can find on the engine. Spray spark plugs and wires with WD40. Good luck
Hey Kelli==You probably will find it if you simply remove the blower motor which is on the pass side of the engine compartment. There are about 6 screws that hold it on and that is it. GoodluckJoe
check your battery cables and you ground. You may want to check your alternator, if the car only starts when jumped started. IMprovement to answer: If the new battery doesn't start the car, obviously it's not the alternator causing the car not to start... Check the starter relay under the hood if it is equipped and if that works then check the starter solenoid located beside the starter motor. If that's working then you can be pretty sure it's the starter motor causing your problem - maybe worn brushes or excess resistance in the circuit.
Try loosening the steering. If the steering column is locked, nothing moves.
