The is a legendary powerplant, known globally for its presence in the Land Cruiser 100 Series, Tundra, and Sequoia. While the engine is "million-mile" durable, performing an engine swap or troubleshooting a wiring fault requires a deep dive into the Engine Control Unit (ECU) pinout .
If you have an engine from a 2005-2007 Tundra or 2006-2011 Land Cruiser, stop using the chart above. You need the "Electronic Throttle Control System" pinout.
If the engine starts for exactly 2 seconds and then stalls, check your IGF wiring. If the ECU doesn't see this confirmation pulse, it cuts off the fuel injectors to prevent unburnt fuel from damaging the catalytic converters. 2uzfe ecu pinout
The standard 2UZ-FE ECU features three primary connectors, usually color-coded or labeled on the housing. While wire colors vary by chassis (Tundra vs. Land Cruiser), the generally remain consistent.
If you can tell me the , model (Tundra, Land Cruiser, Sequoia), and whether it's VVTi , I can provide a more specific pinout or wiring diagram, or tell you which specific connector is for the ignition coils.

Poor grounding (E1) can lead to sporadic sensor readings or complete ECU failure. You need the "Electronic Throttle Control System" pinout
Because there are over a dozen different plug configurations for the 2UZ-FE, you should verify your ECU part number (e.g., ) against a factory service manual.
