My 93 Buick Le Sabre wont start consistently.

you have perhaps corrosion or loose connections at the battery. if you see corrosion brush it away or pour a soda solution on the corrosion. coca cola or any carbonated soft drink has enough soda to burn off corrosion

If "VOLT" or battery symbol is lit when engine is running, the alternator is not charging the battery. Replace alternator.

need more info does car turn over?

is this why you changed the battery,if so did you have the charging system checked first before replacing the battery.it could be the alternator causing the problem and the car running off of the battery until it gets to low on voltage to run the car.the other thing is you could have a voltage draw on the system as well.first you need to have the charging system checked out.

That's really not enough information to diagnose it. It could be a lot of things, starter, battery, fuel or spark problem. I would suggest you follow the trouble-shooting information in the service manual. You can access a free online service manual for your vehicle at:

Check battery connections and make sure they are clean and tight.
IF they are and the battery is tested to be good by a battery load tester, then
the starter could be going bad.

The ignition module is located directly beneath the coil packs up top towards the front of the engine.

please check whether 1 cell of the battery isnt dead .all the lights will still work without 1 cell but the battery wont take the load of the starter.the click sound is the starter relay energising . REPLACE THE BATTERY .

fluid low and possibily need of replaceing try this first. hope this helps?

Replace crank sensor yet?
