Question about 1990 Lexus LS 400

Will not start

Hi there, I have a 1990 Lexus LS 400 and it is not starting. It turns over but, will not start. It seems like the gas is not getting to the carberator. We just replaced the map sensor. This was a problem but now, it will turn over and not start. If it is my fuel pump, how can I tell if it is not working or if the fuel injectors are clogged? We have had this car since Febuary and this is on going. It usually starts after awhile but today...it didn't.

    Someone suggested checking the relay fuse for the fuel pump before we changed it. There is no hum of it starting when we try to start the car.

    Hi again,

    Either that or the fuse. The fuse and/or relay would often be found in the engine bay pretty close to the batter. There would be several. Likewise often, a diagram which shows what fuse/relay for what function as well as its relat5ive location/position would be shown either on top or underneath the lid/cover.

1990 lexus ls 400 security system went off now vehicle will not start. Keys open door turn alarm off but starter will not engage. What can I do?


Your alarm is keep your system from starting. When the alarm system fails, you have 1 of two choices, if it is a after market alarm then just disconnect the alarm, if it is a manufacture alarm then you will need to take it to a company to have then replace the alarm or disconnect it. Doing so yourself you can hurt your vehicle more then help it

My 1990 Lexus LS 400 stalls unexpedly (at any speed).When put in neutral, it starts up and runs fine for a few minutes then stalls again. Why?


Your fuel pump or fuel pressure regulator are not supplying constant fuel pressure. Too much or too little is causing it to kill. You can pull the vacuum line from the regulaor and check for gas. If there is none, you need a pump, it is weak.
