Question about Buick Cars & Trucks
I don't know the model year? I'd make sure battery has a full charge and battery connections all good. You can check voltage and ground circuits at starter motor. Any testing, make sure tranny is in park or neutral and parking brake is set. You may need to use digital multimeter to look at actual voltage?

This sounds like it may be a problem with the passII security sys.
First check the two fuses in the fuse block, #1A and #2E the block is
located under the left side of dash. They may be marked as vehicle anti
theft system(vats)#1A. Fuse #2E may be marked vats/air bags.If these
are good, locate the anti theft relay located above the fuse block.
There will be a yellow wire and a purple wire on each side of the relay,
you wan't to jump the yel wire(A2) to the ppl wire(C1) one of the yellow
wires will run from the relay back up the steering colum. This wire is C1
the ppl wire on the other side of the relay is A2 jump these two wires
and this will bypass the relay. If the car still won't start the problem is
most likely in the colum, either the chip in the key or the resistor in
the ign. lock. You can start the car by locating the purple wire under
the hood in the harness with the blk plastic cover, that runs accross the
firewall. In the same bundle of wires there should be a slightly thicker
red wire, with the key in the on pos. take a sharp knife and cut into
the 2 wires at the same time to make a connection. This will turn the
starter and start the car. If you need to take it to get the key and lock
checked. Hope this helps.
