1UZ FE runs & die. Video

[Gonzalo Bravo]

Hi again

I am trying to make run a JDM 1UZ FE second generation.
Specs are:
Ecu plugs: 34/22/16/28
Ecu N#: 89661-50241
B/R wire feed EFI and W wire feed sensors.

The engine starts, but when should down revs and continue in idle, it stops.
With or without MAF the problem remain the same
Enough Fuel Pressure
Spark is present
Fuel is present
Injectors are ok

This is the video where you can see that starts but stop inmediatly.

Any idea???

Plenty of ideas!
DTCs would pretty much narrow the list )

Personally, I bet you have DTC 13 or 14. Read them out so we know it for sure. Lextreme have a tech article how to do it.

I Got this codes:

15: Ignition Nr 2
21: Main O2 sensor L
27: Sub O2 Sensor L
29: Sub O2 Sensor R
56: ???
78: ???

Question are, What means and what is Ignition 2???
Cant find codes 56 and 78 (fuel pump maybe)

Thanks guys.

Switch the right side coil and wire, ingniters and problem remain the same.-

Done.

With DTC 15, checked the yellow/black wire of the right igniter and found that was switched with yellow/black of MAF.

Now starts, but stop on idle with no new DTCs. Will check it tomorrow.-

56 is JDM only feature, sensor and/or valve for hydro fan
78 is fuel pump relay for slow pump speed
don't mind the o2 related DTCs for now
make sure the DTC 15 is gone

Running it like that with the pipe to the iscv open to the atmosphere will cause all sorts of running/idle issues... Been there learnt the hard way Haha
