Hi all from Tasmania have a Mitsubishi Challenger 2003 v6 Petrol, I think your equivalent in the usa is a Montera Ls Sport 2003. I have no spark no power to ECU. All relays , sensor and fuses have been checked or replaced just in case. Still no power to the ECU . I have managed to get some diagrams but they are not my Ecu model My ECU has 4 Connectors with 3 rows of pins in. If you have the same as mine please please get in touch im desperate now as my old car has a problem and im out of funds nearly, having bought a doner car that turned out not to have the same ecu.

so mine is a 4 connector but has 3 rows of pins need the diagram for the 3 row pin one. This one sadly only has 2 rows of pins per connector

this is the wiring schematic to go with the above ecu. Which again sadly doesnt help me as not quite the same but may assist someone on here. They are from Montera Sport approx 2003 but sadly not same as mine
each. The one Ive managed to find only has 2 rows of pins in each connector. Ill attach the screen shot of it and wiring schematic i got with it in case it can assist anyone else on here. But if anyone has a diagram of the 4 connector 3 rows of pins ECU and the wiring schematic omg Please please get in touch.

 

if, for some reason, you cannot get ECU part number, then look here: https://partsouq.com/
Find you car model (there are too many) and find the ECU part number.

It is much more easy to google the pinouts by ECU number :-)

 

Hi Managed to get it started had to pull out the dash and back trace wiring. As we could notg seem to find a correct diagrtam. Like oh my god. Anyways it was a curcuit under the glove box passenger side that was shorted out. replaced the circuit and car starts and drives. Woot. However the turn signal wont work no indicators coming on when used. The signal lights are all ok as they flash when we lock and the alarm goes on. And of course no wiring diagram to be found for my model for the run indicators. Checked fuses and they are fine hmmmm. will do a new post as soon as I get get my blonde brain around how again.
