Kia Troubleshooting Questions? Ask a Mechanic
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 TestingDo 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 RelayIs there Voltage + on the YELLOW / BLACK wire with the Key in ON position......Not Crank positionLet me know what you find
.IF you need more information, please ask "prior" to Rating..Please do the right thing and leave a rating, using the rating system, so I may be credited for this Q&A..NOTE: Do NOT Rate on how much TIME you waited, because I am not on 24 / 7 and I answer as soon as I see the question.The question will still remain open for follow up questions if needed..If for any reason, you can't rate my answer OKAY, GOOD, or EXCELLENT today.Please reply and let me know why, so I can help more/better..Rating is very Important to our Service.
Automatic or Manual Transmission?
Starter Relay is located in the Under Hood Fuse / Relay Panelclick Attachment below
thanks for the good pictures.........This will likely be the Ignition Switch or the ECMYou posted that the Ignition Switch was replacedThat leaves the ECMUnplug the Ignition Switch & test again to rule out the Ignition SwitchHere is SchematicClick Attachment below
There should only be Voltage + on the BLUE wire at the RelayGround on the BLACK wire at the RelayVoltage + on the YELLOW / BLACK wire at the Relay "only" when Key is turned to CrankThen Voltage + on the RED wire that goes to the StarterIt 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 runsMake sure the Connections at the Starter Motor is not touchingMake sure there is NO Aftermarket or additional wiring at the Ignition Switch wires (remote start, radio, amp, etc)
???You show a picture of the underside with "3" Connecting wiresWHITEBLUEGREEN??Your other picture of the Relay Base shows "4" Connecting PinsAre you on the correct underside Base?
While this may be under the Relay, the Relay Base Pins, are likely insideI 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 problemBe sure we are referring to the "Ignition Switch" & not the Ignition Key Cylinder
Constant 12 volts = GREEN AND BLUEIgnition 12 volts = YELLOW Ignition 2 = ORANGEAccessory = WHITE Starter = REDIF the RED wire has Voltage + "unplugged", with Relay OUT, then there is an issue in the wiring elsewhere
You have a issue with that wire........That is the Voltage + wire from the Ignition Switch to the RelayWhen Ignition Switch is turned to Crank, that wire get 12 Volts + & nothing in Run position or offCan 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
Unplug the ECM & see if the Ignition Switch still shows Voltage + on the RED wire
ECM is located Passenger side under dash
click Attachment belowKia is really bad about diagrams
TCM is for TransmissionECM 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 wireIF you want to use a Outboard Relay:.
SPDT Relay (Single Pole Double Throw)Use a 30 / 40 amp Automotive RelayPins are numbered on relay pinsPIN 87 = Fused 12 Volts Constant (20 amp)PIN 30 = RED wire to Starter SolenoidPIN 85 = Ignition Switch Starter wire +PIN 86 = Ground -
not a problem........
let me know what you find..........
just post back here & I will answer as soon as I see it
at this point........."IF you have unplugged the ECM"........this is not the issueI would replace the Relay first & see if that does it.IF Not, then you need to check the Fues / RElay Box for short internalORGo with a Outboard Relay as I posted
as posted above:SPDT Relay (Single Pole Double Throw)Use a 30 / 40 amp Automotive RelayPins are numbered on relay pinsPIN 87 = Fused 12 Volts Constant (20 amp)PIN 30 = RED wire to Starter SolenoidPIN 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 harnessPlug the Ignition Switch Plug back inCut the RED wire (starter wire) in half at the Ignition SwitchTest the cut RED wire for Voltage + on the cut wire that goes to the Ignition Switch, when you turn the Key to CRANKDoes it have Voltage +??Does it have Voltage + when Key is in ON only position
Thanks.........Wire the SPDT Relay at the Ignition Switch, like this:Constant 12 volts = GREEN or BLUE = PIN 87Cut RED wire that goes to Ignition Switch = PIN 85Ground - = PIN 8612 - 14 Gauge wire = PIN 30Run the 12 - 14 Gauge wire out to the RED wire that goes to the Starter SolenoidCut the RED wire & splice the 12 - 14 Gauge wire to the cut side that goes to the StarterInsulate (tape) any cut wires at the Ignition Switch & Starter
Be sure everything is plugged back inECM, RELAY, Ignition Switch
Test the YELLOW & ORANGE wires of the Ignition Switch with key in CRANK positionDoes either one lose Voltage +?This is ONLY the Starter Circuit & has NO affect on engine running...............
