Hello - I've not used a resource like this before so please bear with me - I own a 1992 Lexus SC300 and am having a chronic problem with the car not starting at what appears to be random intervals. One day I can go out and start the car immediately as if it were brand new. Other days I can turn the car over and the engine will crank but not start. It has very low mileage ( under 38,000 ). When the car starts, it runs beautifully and starts very quickly. The dealer where we purchased it has recommended a diagnostic ($300) to ascertain all problems with the vehicle. I just want the car to run when we need it to and am not interested in learning every possible issue that the dealer would like to repair and be compensated for. I'm only interested in its reliability to start when needed. Also, it's probably worth noting that when we first purchased the vehicle, we had a similar problem which was remediated under warranty and never occurred again until now. Not sure if that's just a coincidence or a replacement part which has reached its useful life and needs replacement.
Thanks very much
