Question about 1992 Lexus Ls 400

1 Answer

Two months ago i had problems with my electrical system. The car shut off and the engine smoked. The mechanic told me that he replaced a module and some broke wires. Before I brought the car home I had the mechanic check the battery and the alternator. He said the they were both strong.A few weeks later the car started jerking a little ,but the car never stopped. The car drove fine until a day ago. All of the sensor lights came on, the radio started giving off a ticking sound and than the car just shut off. I tried to have the battery jumped but the car won't hold the charge. Should I take it back to the auto electrical shop that fixed the module and could it possibly be my alternator.

    one day while driving, as I stepped on the gas pedal all the dash lights flickered, check engine, breaks, od etc... then the next morning it wouldnt start at all. I jumped it and brought it to mechanic. they said a short was causing the battery to drain while the car was off. They said they needed to tear up all the wiring harnesses and I said no and brought it home. Any thoughts on what wire or where could be shorting out? Thanks

Sounds like alt. wasn't charging/or bat wasn't taking charge. take bat to have tasted. if its ok. suspect the alt. with a good bat. the voltage at terminals when running with lights on should be 12-14.5.

Hi Maria,

Does the white smoke occur at start up then go away?
Was it cooler out the night before the white smoke started?

Likely it's condensation burning off.

To be on the safe side have a compression test run on all cylinders. It's a quick, easy and cheap way to find out if the head gasket is ok.

Also, I strongly advise you to get some second or third opinions for the remaining symptoms. Something smells fishy. I'm sure you know what I mean.

If you comment back or repost, I will do my best to help you out.

Best regards
Mike

Couple of months ago would cut out when but start immediately

I dont belive it is air that is cousing your problem. Think it is more an electrical isue. I have had some problems with relay module (engine bay, near engine computer). And check fuel lift pump.
hope it helps

Audi 5000 1985- starting problems


In order to start an engine needs a decent cranking speed, compression, timing, the right amount of fuel and a good spark at the plugs.

When an engine doesn't start, one or more of those things are missing and it is necessary to check each until the culprit is found.

If the engine has a distributor with a vacuum unit it is worth checking the vacuum unit diaphragm for punctures and if it is take a close look at the inside of the distributor cap. Sometimes they develop an invisible conductive coating.

The hall effect module can also cause some problems and the connections can also become oxidised.

If all seems ok, considering the age of the car, I suggest the fuel injectors are removed and tested and ensure the fuel pressure and volume are adequate.

Gauges say no pressure in engine 1995 vw golf


Get someone to check oil pressure with a mechanical gauge, to verify whether you have oil pressure or not. These engine/vehicles, have 2 warning sensors & a control module in the instrument panel. Once you know you have pressure for sure, then you can proceed from there.
