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?

    Sometimes if ignition timing is off, it can effect the starter motor, the starter motor is fighting compression. It cranks slowly then speeds up.

A full tune up consists of spark plugs, distributer cap. wires. rotor for under the cap, air filter and if you want you should change the fuel and oil filter. I hope this helps.

SOURCE: 1999 buick lesabre security light stays on car wont crank

Hello sthomasbf
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.

I did an oil change an tune up for 83 Buick lesabre with not enough oil. All connections hooked up except alternator. But it won't crank. What should I do? An it turns slow when try to crank


1ST make sure the oil level is up to spec. make sure all connections are connected & either charge the battery or boost the battery. If a boost doesn't do the trick, try leaving the booster cables hooked up with the other car running for a few minutes & try starting again. Try that battery charge next. If no luck, u may need a batt, Have a battery voltage test done / load test & starter draw test when fully charged. If u get it running have the alternator checked & ckd for shorts. Good Luck

Try depressing the gas pedal once before cranking. If it fires right up then replace the fuel filter. If not then you may need to replace the cam sensor.

Would appreciate your help


It could be anything. Please describe "doesn't start", do you get power to you dash/headlights, etc? Does the starter wind up, and make a high whining sound. Does it crank very slowly, and die. Does it crank normally, but the engine refuses to fire?
