Customer Question

I just installed a used 1. 5 engine in my 2001 Rio. The engine starts right up but runs only few seconds then shuts off. It will start right back up but again only run few seconds. Same thing over and over. I have a check engine light on so I bought a scanner for OBD2 but can't pull code and will not clear code.

Hey how are you

it sounds like the alarm is triggered on .

was the harness connector identical to the new engine

do you the ECM off the car you got engine from

you will need A KIA scanner or equivalent to reprogram & retrieve fault codes from the anti theft module , the code reader you have probably only read engine codes , does it hook up and says no DTC or it tells no Communication?

the engine cranks & starts and then computer don't recognize the key or a malfunctions in on of the alarm sensors , it thinks somebody stealing it and cut fuel pump .

You Can Try Master Reset If you have not already

Master reset Procedure

1- Disconnect Battery Cables ( Negative & Positive Cables )

2- Hold cables Together for 60 secs ,then let go

3- Wait 15 minute

4- Make sure all doors are closed

5- Reconnect battery Cables

6- Lock & unlock the vehicles using the key from driver door side (if you have a key fob with no blade key, just lock & unlock using the key fob buttons)

7- Enter the vehicle and attempt to start

Please let me know if that works for you

Thank You
