1996 Lexus LS 400 - Answered Questions & Fixed issues

Question edited for clarity, add maker. Question moved to model category. You are the only person the report this issue. https://www.google.com/search?q=1996+Lexus+LS+400+blows+headlight+relay There is a dead short somewhere, but relays can be checked for correct operation and also the two feeds to the relay can be tested. One is 12 volts low amps + and - and the the other is the 12 volts high amps feed + and - to the headlight itself. Operation comes via an instruction from the BCM requested via the stalk switch. You need the Dealership or a good auto electrician. https://www.google.com/search?q=auto+electrician+near+me ..

It is part of the safety restraint system and they are not normally removable. There is help in this link from the Lexus Owners Club. https://www.google.com/search?q=remove+an+electronic+headrest+from+a+1996+Lexus+LS400 ..

While the instrument clusters in all the 1995 ls-400 look the same, they are not created equal. They use different part numbers for the same model year. So the repair depends on the cluster part number itself because different part numbers, means they have different circuits boards, and different parts inside, and this includes the numbering of the capacitor locations inside. So the idea of "which capacitor to look for" depends on the particular circuit board version or part number you have. Incidentally, the "capacitor repair" fix you see on the web to repair the burned out cluster lights issue doesn't apply to the 1995 instrument cluster. It applies to the 1994 and earlier instrument cluster. Similarly, you can't put a 1997 cluster inside a 1995 ls400 because the blue plug on the cluster is a different size. So it's critical the part number of the cluster needs to be identified before you can repair or replace one. The 1995 ls400 could have an instrument cluster with part number 83010-50592 or 83010-50590 or 83010-50600 etc... Instrument clusters are not simply interchangeable with ones with different part numbers either, because the vehicle ECU is programmed to only work with the specific cluster part number that originally came with the vehicle.Also Lexus dealers are no longer replacing these because the part is no longer manufactured. However, you can get them repaired. Search the web for "lexus ls400 instrument cluster repair"Location of part #... This one is 83010-50600...

If oyu have spark, fuel and compression the engine should start.

not enough in the tank

start all over! git rid of fuilter,ole fluid, and flush again. NEW FILTER,GASKET,FLUID, and see tuat will happen. oh! and reprogram the key/fob.lol!

Always go directly to the ground and check it is clean and well connected. I speak mainly here of the body grounds. Battery to starter is fine cause it cranks well and headlights are operable, it's just the battery ground to the body that's giving you trouble. When electrical problems arise, Always go directly to the grounds first.

Try shifting the gear selector into neutral , if an automatic transmission . If it is a standard shift,the clutch pedal switch may be malfunctioning

No, just that one.

Your Airbag is leaking.

Try to google it. Often you can find a utube video that address situation for the DIYer.

the actual panel should pop off with clips holding it in then you can easily access the glass

To answer your question specifically it would be no. There is no inertia switch that feeds the fuel pump that can be turned off or reset . The engine control computer turns on a series of two different relays to control power to the fuel pump. When in the start position the circuit opening relay and the fuel pump relay or both energize causing the fuel pump to run at full pressure or fast speed. From there the engine control computer determines which demand is on the fuel pump and either turns off the fuel pump relay and leaves the circuit opening relay on to supply power through a resistor to slow the pump down for less demand. The EFI main relay is the main supply relay to both of these sub relays. The fuel pump is powered up ultimately by the 20 amp EFI number one fuse. All of these components are located in the fuse box under the hood. If the circuit opening relay is not working it's powered up by the 10 amp ignition fuse inside the vehicle. It's unlikely it is the 10 amp ignition fuse because that powers up a lot of other things also.

First, please post your question only once. There is NO INERTIA SWITCH on your vehicle. The only thing to check is FUSE #1, which is a 20A fuse that provides power to your EFI control. If that is good, check for voltage at the fuel pump when the vehicle is turned on. If it has power to the fuel pump but the fuel pump is not running, replace the fuel pump.

Hard to say but very bad either way. It is going to take some serious investigation and corrective action either way. Biggest issue will likely be where to stop - If you dig in and find a bad wrist pin, do you replace that and button it all up and hope for the best or keep looking and replacing stuff? Good luck and if you have time, add in developments via comment to the original question.

Sorry, but it could be the switch or wiring. Have it checked out..

The entire car NO ONE NO PROFESSIONAL will do what you ask or is needed, regardless of age or mileage That is not the business their in Shops diagnose & repair failed & lots of neglected vehicles To do what is required would take at least $1,000 You need all fluids changed,all filters,ignition parts at least inspected Lots of road testing with scan tool It is 18 years old I would be here for an hour to answer that question

Depends on availability for your model tranny and area you live in. Average is around $300 for a decent used one up to around $700 for one with low miles. Best to just call around and compare.
