Toyota Engine PCM ECM ECU Computer 89661 60021 / 8966160021 LAND CRUISER 

Up for sale is a Working, in excellent condition Toyota Land cruiser truck ECU. My list shows this should fit many 1990 models with the inline 6 - the workhorse for reliability . Typically nothing can kill these, but sometimes a dead ECU WILL! Always keep a spare ECU, even if you don't need it right now. Avoid the unexpected expense of replacing these, they are around $1200 to buy new and typically will be special order which could take weeks. See part numbers at the top of the listing. - . 

This unit offers a 30 day functionality warranty. As always with this type of component your best bet is to match the part number to the one on your original ECU. A faulty ECU is one of the most common no start or random stalling problems with these trucks. these can also cause issues with erroneous check engine lights, idle control problems as well as emission control & cold or hot start problems. I have also seen fuel pump relay turn on faults (ECU won't turn on the fuel pump), as well as an condition where the high speed injector driver has failed. This causes the car to sit and idle fine, but it won't accelerate.If your car does not have these issues but you intend to keep it a while, I recommend our customers keep an extra ECU in the back. These units now have to be special ordered from most dealers new for big $$ (often times over $1000!), and you can never find one when you need one. Even now finding a good one second hand is getting to be quite difficult as these cars get older.
