hello
i have 2009 LX570 with engine dead so i have buy used engine from tundra and installed to my car everything is ok but engine crank but don’t start !!!!
fuel pump ok
spark ok
cylinder compression ok
everything is ok on this engine ( i have video for this engine on the tundra before removal and it ran well)

thx

 

What about the anti theft stuff? Are you sure the harness between the two motors is the same?

 

hello
no anti theft immo is ok
is the same same engine 3UR-FE with same harness

 

If you have fuel, spark & compression the engine should run. You are missing something.

 

yes maybe but what?
Crankshaft Trigger Ring on TUNDRA is the same on LX570 ?

 

Is the green and red anti theft lights blinking? Also are you 100% positive the harness is the same and it's not wired differently. The harness can plug in but does it have the same wires in the same spot etc. Something could be pinned differently.

 

is the original harness from old engine
and anti theft light flash when ignition off
with ignition on anti theft light go off

 

hello
ecm can dead without give any error code?
because i think my problem is the ecm
