Customer Question

How much do you charge for your expertise in 2005 Kia Sorento that the starter engages in the on position and will not cut off.
Submitted: 1 year ago.
Category: Kia
Customer: replied 1 year ago.
I have tried replacing the ignition switch and the starter. The starter has ignition power going to it when the switch is in the run position.

sorry for the delay............

Greetings...... “Hi, I’m Don (aka MOLurch) and I look forward to helping you!”

Is this Automatic or Manual Transmission?
You need to do some Testing
Do you have a Test Light or Volt Meter & know how to use?
IF so, you need to Test the YELLOW / BLACK wire at the Starter Relay
Is there Voltage + on the YELLOW / BLACK wire with the Key in ON position......Not Crank position
Let me know what you find

I have a test light and I know how to use it
Where is the starter relay?
Expert:  Don 'Mo Lurch' replied 1 year ago.

Automatic or Manual Transmission?

Customer: replied 1 year ago.
sorry automatic
Expert:  Don 'Mo Lurch' replied 1 year ago.

Starter Relay is located in the Under Hood Fuse / Relay Panel

Customer: replied 1 year ago.
ok- atatched is what I have and tested. These two have constant power no matter if the ignition switch is in the on or off position
Expert:  Don 'Mo Lurch' replied 1 year ago.

thanks for the good pictures.........
This will likely be the Ignition Switch or the ECM
You posted that the Ignition Switch was replaced
That leaves the ECM
Unplug the Ignition Switch & test again to rule out the Ignition Switch
Here is Schematic

Customer: replied 1 year ago.
I have power on the red, green and blue wires. the switch is unplugged.
Expert:  Don 'Mo Lurch' replied 1 year ago.

There should only be Voltage + on the BLUE wire at the Relay
Ground on the BLACK wire at the Relay
Voltage + on the YELLOW / BLACK wire at the Relay "only" when Key is turned to Crank
Then Voltage + on the RED wire that goes to the Starter
It sounds like you have Voltage on the YELLOW / BLACK wire of the Relay coming in from another source, IF the Ignition Switch is unplugged & the Starter runs
Make sure the Connections at the Starter Motor is not touching
Make sure there is NO Aftermarket or additional wiring at the Ignition Switch wires (remote start, radio, amp, etc)

Customer: replied 1 year ago.
Attached is the wires on the back of my relay. Testing from the bottom of the relay, ALL 3 wires have power.
As you can see, I do not have a black wire on the starter relay, or a yellow / black wire on the relayThe starter does not run with the ignition switch unpluggedNo voltage ont eh red wire going to the starter with switch unpluggedNothing is touchingNo aftermarket wiring
Expert:  Don 'Mo Lurch' replied 1 year ago.

???
You show a picture of the underside with "3" Connecting wires
WHITE
BLUE
GREEN
??
Your other picture of the Relay Base shows "4" Connecting Pins
Are you on the correct underside Base?

Customer: replied 1 year ago.
That is the base from the 4 connector pins- directly under the starter relay that I removed. That is why I was so confused as well.
Customer: replied 1 year ago.
Do you need a different picture of underside of the relays?
Expert:  Don 'Mo Lurch' replied 1 year ago.

While this may be under the Relay, the Relay Base Pins, are likely inside
I believe the Fuse / Relay Panel has to be split apart to get to the Relay Base..........
??

IF you no longer have Voltage + to one of the PINs or the Starter does not run, because the Ignition Switch is disconnected, then the Ignition Switch looks to be the problem
Be sure we are referring to the "Ignition Switch" & not the Ignition Key Cylinder

Customer: replied 1 year ago.
Ok- I tried to split the relay base but I am not comfortable doing that-Ok- I have replaced the ignition switch not the cylinder and it did not change my problem
So with that being said, what wires going to the back of the ignition switch should be hot with it unplugged?
Customer: replied 1 year ago.
here is a pic of my ignition switch unplugged
Expert:  Don 'Mo Lurch' replied 1 year ago.

Constant 12 volts = GREEN AND BLUE
Ignition 12 volts = YELLOW
Ignition 2 = ORANGE
Accessory = WHITE
Starter = RED
IF the RED wire has Voltage + "unplugged", with Relay OUT, then there is an issue in the wiring elsewhere

Customer: replied 1 year ago.
With the switch unplugged and the relay is OUT , the red wire does have power
Expert:  Don 'Mo Lurch' replied 1 year ago.

You have a issue with that wire........
That is the Voltage + wire from the Ignition Switch to the Relay
When Ignition Switch is turned to Crank, that wire get 12 Volts + & nothing in Run position or off
Can be the Internal Circuits of the Fuse / Relay Panel, another wire connected to it, or a shorted Connector from the Ignition Switch Harness to the Relay

Customer: replied 1 year ago.
Can I make a temporary jumper wire from the red wire on the switch to the red starter relay wire?
Customer: replied 1 year ago.
Is the ECM still a possibility and if so could I get one at the junk yard and replace it- is it plug and play?
Expert:  Don 'Mo Lurch' replied 1 year ago.

Unplug the ECM & see if the Ignition Switch still shows Voltage + on the RED wire

Customer: replied 1 year ago.
Is the ECM located on the drivers side left of the steering column under the dash
Expert:  Don 'Mo Lurch' replied 1 year ago.

ECM is located Passenger side under dash

Customer: replied 1 year ago.
I can't find it under the dash on the passenger side
Expert:  Don 'Mo Lurch' replied 1 year ago.

Kia is really bad about diagrams

Customer: replied 1 year ago.
The red wire still has power
Customer: replied 1 year ago.
it is unplugged from the switch , relay is out and ecm is unplugged
Customer: replied 1 year ago.
actually the TCM is what I had unplugged- I still can not locate the ECM
Expert:  Don 'Mo Lurch' replied 1 year ago.

TCM is for Transmission
ECM is in the Passenger side location

You have a short somewhere......
Did you check connections at starter?
Have you traced the Ignition Harness to the Relay Box?
The only things it can be is short, Fuse / Relay Panel shorted, or another wire is added to that starter wire
IF you want to use a Outboard Relay:
.

SPDT Relay (Single Pole Double Throw)
Use a 30 / 40 amp Automotive Relay
Pins are numbered on relay pins
PIN 87 = Fused 12 Volts Constant (20 amp)
PIN 30 = RED wire to Starter Solenoid
PIN 85 = Ignition Switch Starter wire +
PIN 86 = Ground -

Customer: replied 1 year ago.
ok - I did find the ECM and unplugged it- the red wire still has power.
I did check connections at starter-nothing crossed over there
I have not traced the ignition harness to relayI am beat by this thing tonight-
After I try all the this- can I get back to you tomorrow?
Expert:  Don 'Mo Lurch' replied 1 year ago.

not a problem........

let me know what you find..........

.

Customer: replied 1 year ago.
thanks. How do I get you back tomorrow?
Expert:  Don 'Mo Lurch' replied 1 year ago.

sorry......dinner time........

just post back here & I will answer as soon as I see it

thanks

Customer: replied 1 year ago.
Ok- Here is a recap of what I have done and need help-I have ruled out the ECM, Starter and Ignition switch
I also switched the fuse/relay block with a comparable one so that is ruled outIt appears that my Relay pin 87- and 30 have swapped places
I have no power on Pin 87 and constant power on Pin 30What is my next step?
Customer: replied 1 year ago.
ok, I am now having intermittent issue. When I turn the key to on position, sometimes it will engage the starter and sometimes it will not. Then I will start the Kia and the starter continues to engage (wanting to continue start) and I will pull the starter relay and the starter runs like it is supposed to. Then if I try to put the relay back it will engage the starter again and it will continue to engage- however, sometimes if I wait a minute or so- and put the starter relay back in , it is fine and runs like it is suppose to.
Customer: replied 1 year ago.
How can I determine if it is the ECM
Expert:  Don 'Mo Lurch' replied 1 year ago.

at this point........."IF you have unplugged the ECM"........this is not the issue
I would replace the Relay first & see if that does it.
IF Not, then you need to check the Fues / RElay Box for short internal
OR
Go with a Outboard Relay as I posted

Customer: replied 1 year ago.
Ok, if I put an outboard Relay- I need to know colors on the wires and numbers on relay
Customer: replied 1 year ago.
The ECM is out and ignition switch is unplugged. The red wire has power at the plug that goes to the ignition switch
Expert:  Don 'Mo Lurch' replied 1 year ago.

as posted above:
SPDT Relay (Single Pole Double Throw)
Use a 30 / 40 amp Automotive Relay
Pins are numbered on relay pins
PIN 87 = Fused 12 Volts Constant (20 amp)
PIN 30 = RED wire to Starter Solenoid
PIN 85 = Ignition Switch Starter wire +
PIN 86 = Ground -

.

Most Car Stereo Shops will have a 30 / 40 amp SPDT Automotive Relay
.

You can wire the Relay at the Ignition Switch harness
Plug the Ignition Switch Plug back in
Cut the RED wire (starter wire) in half at the Ignition Switch
Test the cut RED wire for Voltage + on the cut wire that goes to the Ignition Switch, when you turn the Key to CRANK
Does it have Voltage +??
Does it have Voltage + when Key is in ON only position

Customer: replied 1 year ago.
See my answers to your questions below:Test the cut RED wire for Voltage + on the cut wire that goes to the Ignition Switch, when you turn the Key to CRANK
Does it have Voltage +?? YES
Does it have Voltage + when Key is in ON only position-- NO
Expert:  Don 'Mo Lurch' replied 1 year ago.

Thanks.........
Wire the SPDT Relay at the Ignition Switch, like this:
Constant 12 volts = GREEN or BLUE = PIN 87
Cut RED wire that goes to Ignition Switch = PIN 85
Ground - = PIN 86
12 - 14 Gauge wire = PIN 30
Run the 12 - 14 Gauge wire out to the RED wire that goes to the Starter Solenoid
Cut the RED wire & splice the 12 - 14 Gauge wire to the cut side that goes to the Starter
Insulate (tape) any cut wires at the Ignition Switch & Starter

NOw it cranks but will not start
Customer: replied 1 year ago.
after doing the above
Expert:  Don 'Mo Lurch' replied 1 year ago.

Be sure everything is plugged back in
ECM, RELAY, Ignition Switch

Test the YELLOW & ORANGE wires of the Ignition Switch with key in CRANK position
Does either one lose Voltage +?
This is ONLY the Starter Circuit & has NO affect on engine running...............
