Hi, can someone help answer this question. I just recently purchased a 1991 LS400 that was sent to a mechanic shop because it overheated. The mechanic said it was just the radiator. The vehicle could start an be moved around for just a bit. But recently, just when I bought the vehicle...it will start but dies out right away. I checked the radiator fluid an it seem to have some on the low line. Just wondering if these vehicles have a sensor or something thats stopping it from starting now. I'm in the process of changing the radiator but also wondering if there's something else I should be changing also. Any help would be appreciated. Thanks

 

u could also change the engine coolant temperature sensor. search and you'll find pictures and step by step tutorial.

 

Thanks, will do. But will those two problems stop the vehicle from starting?

 

check the maf to make sure it's good, then fuel pump, filter, and reset the ECU (not in this order)

 

Thanks. Hope i can get it up an running soon.
