What is wrong with my Chevy Blazer I just bought?

Question

Umm.... I think its the battery.... I can get it going if I jump it but when I let it warm up it will either die or if I try to give it to much gas it dies...... the previous owner thinks it just needs a new batter.

Answer 1

Go and get the battery checked it's free> Wallmart> Auto stores>

Answer 2

it would be better if we knew what year..

Answer 3

"repoff" lol i think its your alternator why you think he solded to you ... new battery will last you like a week if you dont used a radio or anything else if u want get the new battery and turn on find the its the alternate go to the nears shop so you can get it check

Answer 4

Just the place for an inexpensive volt meter which is right on your dash. If it's charging 13.5 -14.2 volts the alternator is charging the battery. However, if you check the battery with a hand held volt meter with the motor off it should read 12.85 volts IF it's fully charged. If it has the origional battery and it's more them 4 yrs. old check it out with a volt meter or take it somewhere for a load test.

Answer 5

Once you jump it off, it would run with a bad battery if the alternator was working, so I think you need an alternator.

Answer 6

if the batterys dead and the alternater dont work ,when its dead u dont get power to your ignition, could be your alternater.take it off and your battery out and have them tested. autozone does it for free

Answer 7

(While it's running) take the pos.+ (red) battery cable loose. If it stays running your altenator is good (but battery is bad). If it dies imedeatly then your altenator is bad. (battery could still be bad but this is what kills it).

Answer 8

could be battery if it runs fine when jumped

make sure it's charging first

Answer 9

I dont think its a new battery that is going to solve your problem.  Once started, the battery should be charged enough to keep the engine running. You got another problem.  Take it to a reputable mechanic for a diagnosis.
