sometimes it does and sometimes not

 

with whats posted, nope, i won't even try to guess.
its like asking how many pounds are in a foot.

we need more info, what year is your car, what trans, what motor did it come with, is it TBI, carb, TPI? does it have VATS?

 

Obviously there's a lack of info to give you any sound advise on this matter. However, in ALOT of cases where car guys try to find out why a car won't turn over, they tend to search all over for faults. like fuel pump, ignition etc etc.

While THE most common reason is still a flat battery!! Even so, alot of knowledgable guys search for all kinds of different sources. Even seen on monster garage.

A battery can be destroyed fairly quickly if you let the car sit. And lets face it, our cars tend to sit alot, either for upgrades, repairs, winther storage etc. I've had batteries go bad in just 6 weeks from sitting. If you have an alarmsystem, it drains it slowly, and sitting with a low charge, it's only a matter of days before it's destroyed for good.

DO yourself a favor, and try starting it with a battery you KNOW is good, not one you think is good, or was at one time...
