What is the pattern arrangement for firing pluck wires in kia sorento 3.5 v6 petrol engine for 2005 kia sorento lx model

Which engine do you have fitted? Is it a Petrol or a Diesel? They did four different engine sizes which were either an inline 4 cylinder or a V6. The firing orders are different between V6 and inline 4 cylinder engines so please use the comment section below and I'll try to give you more help.

No such thing as a single ECU diagram. Wiring diagrams are arranged by system, not component. See this post on how to get the right wiring diagram How to get car wiring diagram Ricks Free Auto Repair Advice

I guess you mean the dash lights up but the engine does not crank over at all. Turn on headlamps and try it. If lamps dim, can be bad battery connections, bad solenoid or starter. If lights do not dim, bad solenoid, ignition switch or starter solenoid wiring.

Could also be an injector or vac leak.
The code means the cylinder did not fire and there was a drop in RPM not that the spark plug did not actually fire.

have your mechanic check valve timing and test the cam and crank angle sensors also check the wiring to the coils
