Question about 1990 Lexus LS 400
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.

I have a 1990 Lexus ls 400, I had an issue with the alternator. I changed it, and now the car will die with out warning. Sometimes it will drive for several miles, other times it will turn over and shut right back off. I have had the computer diagnose done and it doesn't pull any codes... checked the ignitors, the crank censors, and the cam censors... dont know what else to try
