2011 Kia Sedona 108 K miles,
Intermittent No crank, No start,
It’s been happening for a year now randomly lately its been happening a lot,
First I checked the battery and its connections its all good,
Second check the fuse box and starter Relay, which might not help because its random,
Third I suspected the key could be defected which prevent it from starting but I have 2 keys and it’s the same with both, so its less likely,
Fourth I suspected Neutral Safety Switch which allows the engine to start if the shifter is in Park or Neutral only, but if its defective it will prevent the car from starting so I replaced it since its $40.00, and its easy to get to,
That did not solve the problem, I need to investigate if the starter is good or not, you can remove the starter relay and jump the contact terminals Terminal 87 & Terminal 30 make sure the shifter in Park position, even if the key is not in the ignition the starter should spin if not defective but the engine wont start, now you know starter is OK,
put the keys in the ignition and turn to on position of course keep shifter in Park and jump the starter as I explain before if the engine starts then the problem is the relay, which it was in this case, even though it clicks and as you can see, the problem is the contacts inside the relay they get dirty due to humidity temperature change and its old 108K miles ( Never Trust a Relay) so I replaced it with a new one it is only $12.00 from Autozone and that solve the No crank No start issue, also I would keep a jumper wire and a Spare Relay in the vehicle just incase other relays or accessories malfunction so you can use the same method to test whether it’s the relay or something else, most relays work the same way and have similar terminals diagram. I hope this helps thanks for watching
