when my problem started I had turned off my car and it would not start like it was out of gas. the next day it started up and ran fine,untill i turned it off, then it would run for just seconds and die out. I let it set for a few month and had to replace the battery I figure I had reset the computer because it ran supper for about 2 months it was running after sitting over night until i turned it off, then it would just start for seconds it want. now it has gotten to the point where it only starts and runs for 10 to 15 seconds
will not start on 1992 Lexus SC300
fIND SOMEONE IWTH THE IGNITER CONTROL MODULE LOCATED JUST BEHIND THE FUSE BOX WITH WIRES RUNNING TO IT ITS IS ABOUT 3/4" THINK AND 3-4" PUGGED IN...iGNITER MAY BE BAD.
Really, you need to have some one do a thorough inspection. I would start with a fuel pressure and volume check while the car is 'misbehaving'.
check your fuel injectors
did you fix this? because my lexus sc300 is doing the same thing. How did you fix this?
