Car won't start or crank

Have you tried giving the vehicle a jump ? Also try putting vehicle in neutral and try to start. If still no start either bad ignition switch or starter.

IDoes the security light flash in the dashboard when the key is turned?

My Buick Century Doing The Same. What Exactly Did You Do To Crank It Or Get It Back Running?

I believe the VATS (Vehicle Anti Theft System) prevents the car from starting. You have to reset the car computer some how.

Clean Yorkie get a fine sandpaper get in between the grooves and on your key or too little prongs towards the bottom of the thick part of the key and that's the security system that engages it make sure that's cleaned out and it will fire right up

Same thing new starter new ignition switch, can jump the starter and it is turning the motor, car was in a small accident front passenger side drove fine for a day and then parked it because no headlight, finally got parts went to start it to put in garage and nothing

I put it in neutral and it started right up. Mine has been doing this and it usually works, don’t know what the main issue is. Maybe a loose cable cause I just change the starter not too long ago

We have changed battery Radiator has a crack Used Gold seal What is going on 99 buick century still wont start

99 buick Century Will not turn over Gas in there Radiator does have leak Battery brandnew What is going on

My 2003 Buick Regal LS is doing this!!!

Could be shortage In circuit...missing ground connections on the engine...resistance from battery to starter

I got a 2002 Buick Century I have no key for it and steering wheel lock I had to jam back in to the steering wheel so I can move it and the gear shifter I had to unplug the sensor for so I can put it in gear I have to start my car by the solenoid but I rigged it up I took a wire hand wrapped around both Hots on the solenoid so when I take my hot battery Tynamo off all I have to do it just touch the hot to the hot on the battery for my car to start over but it won't crank and it's been sitting for like 9 or 10 months why won't my car start up and I took the starter apart and cleaned it really good again why won't my car start up

I've already cleaned all the wires and made sure there was wires where are they need to be

Where the key goes the guy I got it from where the key goes there's two white wires behind it when dude took ripped off that plastic piece a ripped the two white wires apart for the security I tried putting them back together you still won't crank so I took the wires apart and switch them around it's still not trying to crank

yeh just went thru alot of trouble shooting for 2002 century ...we were going to do starter motor but it bump starts of the solenoid and hot ...we bypassed vats with GATOR bypass ...am thinking its either corosion microscopic layer in between electrical connectorsa and grounds ..sometimes i could start the car and sometimes not ...ois it the relay then is it the battery then is it the neutral safety switch not fully connected underneath or the automatic gear shift lever doesnt carry the neutral sensor all the way on spot ...i took off the top of the sterring column cover for now and now its starting everytime ...so it could be need to go under neath and see if an adjiustment can be made to remedy the problem ...since i bypassed the vats i can use a new ign switch not chipped for chipped keys as the bypass will allow you to automatically have the right ohms resistance to fire the computer up and start the beast ... i still havent taken the top of the column cover off its a bitch to get off ...the bottom cover off and thre top not seated down hard woith screws is allowing ? contact ? for starting cus the gear lever structure isnt limited anymore by covers and oir the unscrewed loose column cover top is allowing slak in the 2 wires coming from the ign switch or the ign switch is not good but then it wouldnt start the car ....yes its no cake walk ..people have replaced battery alternator relay ign switch etc at a huge cost and the dam thing still woodnt start ..not lol ..im gonna gpo with an underneath exam to see where the neutral saftey switch is and whether it is adjusted right or just bypass it ...

Put in a new battery bc the old one kept dying, after replacement the car wouldn’t even start or crank but had power lights worked everything. Tried putting on the cables again, nothing. I’ve tried this once before and it work so I just turned the key put it in neutral turned it till the light were on then gave it a crank and it started right up. Good luck. Lol -Buick century custom 1999

AAMCO checks it for free they say it is the safety switch PDRLN which is faulty.They charge a lot because they change a lot of staff....all connected but I am decided to give it a try with an inexpensive switch from Autozone and find a good ASE certified mechanic to fix ONLY what is wrong.

two words folks...CRANKSHAFT SENSOR Thank me later
