#109 of 168 1997 Buick LeSabre Engine Light Suddenly Won't Go Out by nikkiro74 Mar 07, 2009 (6:14 am)
I have a 97 Buick LeSabre Custom that I bought a couple of months ago. It needed a new engine, and I had one installed shortly afterwards, new oil put in, the whole nine yards. It's been running fine up until a couple of days ago. Suddenly it started knocking and cutting off, the engine light won't go out, I bought new plugs and had them installed but the engine light still won't go out! What else could be wrong with my car? I checked the oil, and it has oil, it has water, so those are not the problem. Please help! Replies to this message: imidazol97 (Mar 07, 2009 11:30 am)

Replying to: Michael8087 (Feb 13, 2009 10:18 am) Do you have the automatic digital readout temperature control? It might be an actuator that's got a cracked gear on the heater box; the actuators are electric motors with gears that move the vanes inside the heater. They crack. Often it occurs when someone replaces a battery and disconnects the power for a while without turn the heater OFF while the key is ON so it "parks."   How is your coolant level inside the radiator? My first guess would be an air bubble in the heater core. If the radiator is staying completely full... when the car is completely hot after driving a long time, run the motor up to 2500 for 10 seconds in neutral, repeat 4 more times. That is supposed to push air out of the heater.   Also, sometimes people get an air bubble into the radiator so to fill completely, have someone run the motor at above idle while the cap is off and you'll see the level drop. When that happens fill the radiator full and put the cap back on. Then they can slow the motor back down.

Replying to: nikkiro74 (Mar 07, 2009 6:14 am) >It needed a new engine,   Go back to where you bought it. It must have had a warranty since it was new.   My thought would be a sensor or something major has happened because of the knocking. If it's a spark knock that might be sensor; otherwise, it's a problem. It needs to be diagnosed and just putting parts on hoping is going to be expensive.
#112 of 168 2002 Buick LeSabre Custom will not start by rginsc Mar 07, 2009 (5:52 pm)
Help….I have a 2002 Buick LeSabre Custom with a 3.8 engine. After you have driven the car for a while and you stop and then try and start the car again it will not start. The lights come on but it will not turn over. If you let the car sit for about two hours the car will start. Any help or suggestions will be greatly appreciated.

Replying to: rginsc (Mar 07, 2009 5:52 pm) My first guess is a faulty starter relay or starter solenoid.

Replying to: rginsc (Mar 07, 2009 5:52 pm) Check connections from battery to starter. I always tighten them to move them to make sure the corrosion is broken between contacts. Tighten the little contacts on the solenoid on the starter. Check the ground on the floor pan under the rear seat and tighten it.   Another check is to use something like a light hammer or heavy screwdriver to tap the starter housing when it doesn't start. Sometimes this causes the solenoid contact to make connection through the damage or sticking. It verifies the starter is the problem. I got a rebuilt from a local AC/Delco rebuilder. I felt much better with that than getting a rebuilt from the competitive box stores where cheapest cost is best for them.   The neighbor helping me with my older Buick even used a battery charger/jumper unit and directly connected to the post on the starter to verify that it wouldn't turn.

I have a 1991 lesabre 6cyl. Car will start but when you drop it into gear it dies and won't start for awhile. Any idea what it could be? It will turn over but not catch.

Replying to: cfd110 (Mar 09, 2009 2:21 pm) One possibility is that the solenoid that handles the transmission lockup is jammed.
