I got a 2003 hyundai elentra gt
Without more info and what you did and pics, there is no way to know how to proceed. Did you hook up the ground? Is it exactly the same engine? If not, you will need to reprogram or use another ECM.
Yes I hook up everything but the only thing is the that engine Dose not have on sensor on is the valve timing actuator ?
there is your answer.
I don’t have the wire Harness for that engine I use the one of my Elantra gt 2003 so do I have to change the ecm n the wire harness ?
