Hi there! Does it click or anything or no sound at all when turning the key?
Ask Your Own Hyundai Question
Customer reply replied 6 years ago
no sound but eventualy it starts takes a while though
Ok, with no sound at first, I would go after the neutral safety switch on the transmission.
It may just be out of adjustment,try moving the shifter in and out of park while holding the key in the start position and see if it improves.
Let me know!

Customer reply replied 6 years ago
I do hear 1 slight click when a turn key then nothing
Ok, do you have a test light or volt meter?
Also, does the car have a factory alarm on it?

Customer reply replied 6 years ago
i do have a volt meter and no there is not factory alarm i had a after market one installed but i had then disconnect the brain for it but the wires are hooked up still
Ok, you need to find the transmission range switch. This is at the end of the shift cable out on the transmission.
You need to locate and test the purple wire in the harness for power with the key in the start position(you will need a helper) then check the yellow wire for power the same way.
This will test the switch. You should have battery power on both wires when the key is in the start position.
Let me know!

is it located right next to the tranny dipstick there looks to be the shifter linkage there with a harness with a lot of wires
Yep, that is the one!
Need to locate that purple wire and test that first. Remember,battery voltage with the key in the start position.
Then run the same test on the yellow.
The purple provides the power in, and the yellow the power out. So, if you have no power in, then we work back to the ignition, if you have no power out, then this switch is replaced.
If you have both, the next step is to head to the starter relay to check for power.
Let me know how it goes!

there is power goin in but i can get a good read off yell cause theres no bare part showing
You have to make it happen.
Try this, go to the start relay in the fuse box under the hood.
Pull the relay, one slot should have contant power, then one of the others should get power when you put the key to the start position.

starter relay or ignition swith? sry not to mechanicly inclined
Starter relay, I think it is labeled start relay in the fuse box under the hood.

ok i had power as key turns also i switched the fuses from rad fan and it started then i replaced it back with the old one and it started could it be the fuse the whole time?
You swapped a fuse or the relay?
Ask Your Own Hyundai Question
Customer reply replied 6 years ago
the big one i assume is the relay it says starter relay
Yes, if you swapped the relay and the car started, the relay has been the problem all along.
Just needed some testing is all.
Don't leave out the cooling fan relay however, you need that one!
Swap it for the a/c relay if they are the same until you can get a replacement relay.
Ask Your Own Hyundai Question
Customer reply replied 6 years ago
well after it started i swapped bad one back in and it started again with " bad fuse" is that because it had enough juice from the start previous start with good fuse
No, that would be because you had a bad connection at the relay or possibly the switch on the transmission. Playing with the wires will sometimes reseat the connection and make it all good.
