Question about 1995 Buick LeSabre

1 Answer

Engine burps My engine stops intermittently and all of the indicator lights come on. Sometime it restarts itself in a few seconds and other times I have to shift to neutral and restart. This happens hot or cold. Took the car to a Buick Dealer and they said no codes showed up and over $500 later, with no satisfaction, I took the car back. Been doing this for over two years Otherwise I love this car and want to get it repaired.

    About 5 months before the problem started I had the tank dropped and the fuel pump and filter assembly replaced because of a noisy fuel pump. I haven't check for water since.

    Have not tried the crankshaft sensor yet. Can get one for about $45 but have to see where it is located on my 95 Buick.

    Had a crankshaft sensor go bad on my 98 Cadillac catera but it would always die about 15 minutes after start up and then I had to wait till it cooled before it would start again.

    On my Buick, the engine can dia at any time, hot or cold, today or 3 days from now.

    I have the same thing happening. I changed my Crank sensor because a history code read "wrong frequency at crank" that seamed like a logical thing to do. Don't worry, it is easy to change (took me longer to get the pulley off than to change the sensor. and who puts 250 ft lbs on a bolt?)
    anyway I also have another code in my history that says
    "P162 anti theft fuel enable circuit"
    The only difference with my symptoms is that my car always restarts. without waiting.
    It is also worth noting that I had to replace the ABS computer

    I'd give it a check...after I posted my reply I remembered a vehicle that ended up in my shop that no one could figure out...I found a shop rag in the fuel tank!!! Not saying that's what you will find but unless I was there and looked everything over myself, that's where I'd recommend to look first.

    Has anyone ever checked to see if there is any water in your gas tank??? (actually removed it and looked inside)

How can I troubleshoot ignition switch?

If the lights in the dash come on when it dies, then the switch is working. Might want to check for codes. Even if the engine light isn't on. Intermittent problems don't turn the light on, but are stored in history codes. Check the battery to body ground.

Why do I have an intermittent problem with ABS and power steering lights?

Bad or loose intermittent wire connections to and from sensors. Some unauthorised mechanic has been working on the car? Take it back and talk to the service manager, or the shop owner.

2003 Sunfire automatic 245000km runs well, engine stops while driving, clicking under the dash, then restarts , runs fine until next time

with the details that you have provided, it sounds like it may be either a ground, or ignition relay, but I've also encountered the same problem being the starter wire to the starter. The reason I think that is because of your dash lights coming back on .If you have use of a voltmeter you can test and see how much power is actually going to the starter An ignition relay could do the same, but usually won't interrupt the engine after it's running.

My 1993 nissan sentra 1.6 wont run and check engine light wont turn on,bulb is ok

Could be any of several things. If the crank sensor is marginal and not sending pulses, the fuel pump is shut off. This is for safety. The pump is energized for a few seconds as key is turned in preparation for starting then engine must rotate normally to keep the pump on. If it stops, in a few seconds the fuel is cut off.

Clock indicator disappears after driving for a while

Sounds like the clock itself is going bad. Intermittent operation is a pretty common indication that the clock is beginning to fail internally. I offer a reasonable repair service; check out

My 2004 Jeep Grand Cherokee's engine light comes on and then goes off by itself and it's been doing this for months now. We were in stop and go traffic over the weekend and light was on, now with normal...

You can take the vehicle to an advanced auto or autozone and get a free engine diagnostic. They will even give you a print out of the code or parts needed. I would do that before going on any long trip because there's a lot of vital sensors and parts wired into the engine light. Hope everything works out for you.
