YRV won't go

Forum: 

HELP! I've just fitted a second hand engine to my wife's 1.3 YRV 4 Trak and now it won't start. It starts for a second or two just as the starter is engaged but it just won't continue to run. Any ideas chaps?

Won't Go !

Don't like the new shape much.

I wonder if it is something to do with the ECU or other electronics on the YRV?

I have been led to understand the engine and electronics are set up for each other.
If you have changed the engine but kept the original Electronics there may be something that needs to be done to make them compatible !

I just think I read this somewhere. Maybe I'm talking rubbish !
For your sake I hope I am.

But if not, there are Companies that will come out and do it for you, similar to re tuning your ECU for more power etc.

Good Luck.

Oh No. I think I was right.

OUTLINE
This system consists of a transponder-built-in key, an antenna coil, an immobilizer ECU and EFI ECU.
In this immobilizer system, if the key ID code can not be collated or the rolling code is not matched with
each other, the EFI ECU stops the ignition and fuel injection, thereby stopping the engine operation. The
key ID code is a transponder intrinsic code, whereas the rolling code takes a different value every time the
engine is started. This code is renewed and memorized in the EFI ECU and immobilizer ECU as the rolling
code for the next starting.

I have taken this directly from my Sirion Workshop Manual.
I would think the YRV will be the same!

I will look and see if it gives a fix ok. May take sometime if I find anything at all!!

Hopefully Fix for your YRV.

The vehicle is provided with one master key and two sub
keys. However, up to three sub keys can be memorized in the
immobilizer ECU by using the sub key registration function of
the master key.
CAUTION:
•?The master key (black) has the sub key registration
function. Hence, be very careful not to lose or damage
the master key.
•?If the master key is lost or damaged, it is imperative to
erase the memory of the immobilizer ECU and to reregister
the master key and sub keys, using the diagnosis
system (DS-21).
(1) Connect the jump wire between test terminal and earth
terminal.
(2) Start the engine, using the master key.
When the engine starts, the key registration mode is
assumed.
(3) Stop the engine. Within ten seconds after the engine
stopped, start the engine with the sub key.
When the engine starts, this sub key is memorized in
the immobilizer ECU.
(4) To register the next sub key, repeat the steps (1)
through (3).
CAUTION:
•?In the key registration mode, the memories of all sub
keys are erased. It is, therefore, imperative to register
the all sub keys when a new key is added.
(5) After all sub keys have been registered, remove the
jump wire from the diagnosis connector.
Diablo Ensure that the engine starts with all keys.

Hi Bob, Dunno what happened

Hi Bob,

Dunno what happened there I replied to you yesterday but must have hit the wrong key or something cos my post's not here Blush Anyway I have swapped all the sensors for the originals having heard a similar thing about them being matched to the ECU but still no luck Cray 2 I'm reluctant to try the key thingy as the fuel pump is actually running so I don't think it is that. Any more ideas chaps Help

I don't think youve much choice to be honest.
