I have a 97 buick cenetry it will not crank. We have tried jumping then
change the starter and relays .
When I turn the key it on the radio and lights will come on but when I try to
turn it over I loss all power. It ran great all day yesterday and started
everytime without hesation. but the last time I tried to crank it nothing! I
may have touch the key (it has a chip of some kind) to a magnetic sign.
(would that be the problem And if so wouldn't it cause the radio and light
not work as well?)
The key to the Buick of that year contains a resistor as part of the
system, but it would not be affected by magnetism.
Having said that, the resistor or key reading device COULD be defective.
This happens relatively often, especially in aging cars. If the passkey
is not reading the key properly, you will get a no crank situation. Not
I thought if the resistor in the key failed the power stayed on, you just
a 'security' light on the dash and it didn't crank?
Since it looses all power, I'd suspect the main power feed from the battery
or the ground strap.
Agreed, it does not lose all power. I read that in the OP, but was not sure
interpret what he was saying. On mine, when the security system is armed,
try to start the car, the dash lights, etc, go off, but the starter will not
If he jumped it directly to the starter, the starter should crank the engine
over, if the
security system were armed, but it should not start. The security system
fuel injectors simultaneously with cranking (not armed), but if you jumped
directly (system armed) , this does not happen, so it should not start.
