No power to the starter solenoid

This sounds like the starter solenoid isn't getting enough power. Jumping the solenoid is you simply bypassing it. Go back to basics. I may suggest things here you have already done but it helps to treat this as a simple check list.
- Check the fuse, sometimes the fix is that easy.
- Check the relay for the starter motor. It should click when the key is turned sending power to the solenoid.
- Check the voltage supply at the small wires at the solenoid. Using a multi meter set to DC Volts you should get around 12 volts when you turn the key. You might need a helper to do this.

More involved then just a few thing's like other guy posted . The ignition switch is not a direct connection to the starter solenoid S terminal . Input to a computer , BCM - body control module , PCM - engine computer , TIPM - totally integrated power module etc... one of these modules (computers) energizes the starter relay sending battery voltage to the starter solenoid there by engauging the starter to spin the engine around. The starter relay contacts could be sticking .

Do you know what a wiring diagram is ? How to use a DMM - digital multi-meter to diagnose automotive electrical circuit's ? Looking at a wiring diagram to see what all is involved in the starter circuit , main battery cables , park neutral safety switch , starter relay etc.. Find video's on youtube . Do you have a manual or automatic trans. ? The purple wire get's B+ voltage from the starter relay in the underhood fuse / relay box .

code p0700 is the transmission control module (TCM) fault.. Check that there is power from the ignition switch in the start position either to the starter solenoid or to the starter relay.. If there is power tom the solenoid then the fault may be in the solenoid. IF there is power to the relay and it clicks then the fault may be in the relay (check voltage on the starter wire out ) or the starter solenoid.

Definitely a starting system problem. That sound you hear in the back is the fuel pump.

Starting system circuit components (besides wiring harness)
1. Ignition Key Switch - closes the starter relay control circuit to energize the relay and close the contacts inside the relay (you can check this by locating the relay in the underhood fuse/relay box and have a friend turn the key while you listen/feel if the relay 'clicks'
2. Starter Relay or its Contacts
3. Starter Solenoid - pushes/pulls the starter gear into the engine's flywheel ring-gear and its contacts close to provide battery power to the starter itself.
4. Starter itself - poor brush contact with the armature's commutator will prevent the starter to spin/turn

If you are 'Electrically' talented, you can check to see if you're getting battery power to the starter solenoid by using a simple 12 volt test light/bulb. Connect one lead to the starter solenoid terminal and the other to chassis/engine ground and have a buddy turn the ignition key - if the light turns 'ON', then you know that particular circuit is OK but the starter solenoid is not energizing to push the starter gear into the flywheel ring-gear to turn the engine over. If it doesn't, the problem is elsewhere (wiring, starter relay, starter relay control circuit, etc).

You can have a qualified Hyundai Service Technician properly diagnose your vehicle. OR, you can Go to www.hmaservice.com and register your vehicle by VIN #.. you'll then have access to wiring diagrams, shop manuals, service bulletins, illustrations, etc.

What year is your case? It will be either the Ignition cylinder or wiring short if an older model.Could also be your starter solenoid.

That's possible, but if you have power at the starter solenoid to close the contacts then check to see if the 12 volts are going through it(probe the large wire on both sides of the solenoid for 12 volts) and on to the starter, if this is the case, check for 12 volts at the starter lug where the large power wire hooks to the starter, if you are getting at least 12 volts at the starter lug, I would say you have a failed starter motor. Good luck !

do you have power from the switch to the starter solenoid ? What you should have is a battery lead going to the starter relay / solenoid. a battery lead coming from the relay / solenoid to the starter and a 12 or 14 gauge wire coming from the switch to the relay solenoid. Depending on the age of the machine this wire may actually go direct to the solenoid or it may have to go through a couple of safety switches. the first thing I would check is make sure you have power coming out of the starter switch to the start circuit. The terminal on the switch is usually marked with an s for starter / solenoid. If you have power coming out from here then trace this wire to either a safety switch or relay solenoid, keep checking for 12 vdc until you dont have power and you will either find the problem or the bad part... hope this helps you

There are two ways to hook up an immobilizer on a car. One is to break the continuity of the ignition system power suplly. This would result in an engine that cranks but wont start. Another way is to break the continuity of the starting relay. If an installer knows what he is doing he would wire it so that the relay wont get power to the coil. This would result in a car that don't even click when you turn the key so I doubt it is the immobilizer. If the starting relay clicks, the contacts on the relay might be worn out, and not getting enough current to drive the solenoid. One way to check this is by using a volt meter. And check to see if there are voltages going to the starter solenoid, when the key is turned. It should be almost the same as battery voltage. If the voltage going there are no voltage going to the solenoid, or the voltage going there is low, for exmple 8 volts then the contact on the relay is bad. Remember this is if the relay clicks. If the click is loud, and coming from the starter itself but it wont turn, replace the starter, that means the starter solenoid is bad, or if you can buy just the solenoid it maybe cheaper, but you have to know how to take a starter apart, I dont recommend that tho. Good luck these should solve the problem.

I would go for the starter motor personally first, as thats the part that cranks the engine over :)

that gets power, then it starts turning the flywheel, the starter motor also keeps the engine running inbetween the engines power strokes while its running.

Go for the starter relay & the starter motor :)

Thanks.
