2007 Santa Fe. No voltage to engage the starter relay. Sign In

I'm currently having problem with Santa Fe (2007) not starting. At first I thought it was the starter relay, but after replacing the relay, I'm still having problem with the car starting only sometimes. So I took out the cover on the starter relay. I manually pushed the relay while my friend put the key on ignition, and the car started. I measured the voltage that suppose to engage the starter and it's showing 12 volt couple times but most of the times, it's just blank.
I can manually start the car anytime, but it's requiring me 2 people to do so with manually closing the starter relay to start the car.
I even open the entire fuse & relay box just to see if anything thing under was causing connection problem.

What specific parts should I look for in this situation?
Is there another relay that engages the starter relay when the key is on ignition?

Any help is greatly appreciated!!!

You likely have an alarm that is interfering with the circuit. I would try locking all the doors and and then unlocking from the drivers door with the key or the clicker.

Also check the "start" fuse (10amp) in the instrument panel fuse box.

thank you for the reply. I tried your troubleshoot and it seems that the car is working fine (I wouldn't know for sure yet). I also troubleshoot the starter relay terminal with multimeter for Transaxle Range Switch which came out fine. So I'm down to burglar alarm relay and ignition switch, but based on the answers I got from hyundai forum and this forum, I'm thinking burglar alarm relay is the problem not ignition switch.
What do you think?

I think you're trying to guess at something that should be tested instead.

Here is the wiring diagram. Test to find out what is or isn't where it should be.

I did some testing. I got 0 to 1 ohm on one side of terminal on starter relay, so I knew that trans axial switch is good. but I don't have any voltage on the other side of the terminal. But, it's definitely something with burglar system/door is causing the no voltage problem. Whenever the car is not starting, I just lock and unlock the car and the car starts with no problem, so I try to find the burglar alarm relay in fuse panel inside & outside, but it's not there. I think it's all put together as this thing called ETACS box. That would be something out of my hand and finally give up and bring it to a dealership or something...

But thank you so much for the all the trouble you went through helping me!

If locking and unlocking the doors makes the car start, that proves the relay and system are working. Something is making the system arm when it shouldn't or not disarm when it should and that is controlled by the BCM which gets you into some real technical testing.

would it be better to go to dealership for these electronic issue? I don't know if normal shop would be able to handle this even though I feel like it's gonna be cheaper at normal shop... Thank you again. It's better to spend money on things I know what is going on.

There are independent shops that are capable of this but it's about 10% of the shops out there. You can't go wrong with the dealer, even if it costs a little more.
