dead battery?

has anyone ever heard of a battery having a dead cell and then turning on the
defense mechanism of the computer so your car won't start? my stepson's
hyundai accent wouldn't start and i got 12 volts at the battery and at the
wiring harness to the coils. the coils and crankshaft postion sensor were new.
the dealer charged him $118.00 for the battery and now it runs ,where before
we got no spark, even if i jumped it with a portable power pack. any thoughts?
thanks

 

Your dealer fixed the real problem and charged you for a battery as
compensation. If the car is running ok you came out rather cheap IMHO.

what was the real problem? and how do you figure $518.00 is cheap! they put
in 2 new coils and a crankshaft position sensor and that lasted 2 days . then
the battery was next. i think they ripped him off.

 

Regardless of the other work performed Randy, I still think the charge for
the battery was a rip. I don't care how dealers attempt to justify it, but
a battery diagnosis is simply not worth what they charge. You can go to any
aftermarket auto parts store that sells batteries and get the charging
system checked out for free, and they'll install the new battery for you at
no charge. This isn't high tech service and there is enough margin in a
battery to cover the simple act of replacing one.

 

my thoughts exactly Mike . inever thoght it was the battery though because i
checked it with my voltmeter and was still getting around 12.5 volts there
and at the coil harness. then i figured if it was a little weak my jumper
starter pak should have compensated for the low voltage because the car
turned over fine but no spark at the plugs.? thanks Randy
