Isn't there a little box with the spare key chip in it if so replace the chip with a new one @@ first try this
Activate the Key Fob. Many manufactures will not allow the car to start when the panic button has been pushed. Hold down the panic button for five seconds to reset the immobilizer. Next, push the lock button two times and wait ten feet away from the car for ten minutes.

Well, ya might wanna do the Math; the money you spent for the New ECU, Plus reprogramming, Plus a new Valve timing belt, Plus other issues which are not evident because, the Car isn't running... I'm pretty sure we've past the Car's value.
You need the Key that is for that ECU
A *new key needs to be programed into the ECU
Also, since the ECU has been unplugged for x amount of time; The ECU needs to be programed, Now
*Your OLD Key may not be readable.
For do it yourselfers; When replacing PCM/ECUs,
Body PCMs, Programable Fuel injection, Instruments and such... with used parts
Recommend; getting access to a complete RUNNING donner Car at Pick and Pull or Pull Part or...
Sorry, I'd like to help but, Seems to me a Dealer only problem at this point.

The problem is in your steering wheel

There is a chip in the key on the newer cars. The dealer should be able to send your information to Hyundai and order a new key. Pricey. Check with another dealer.

Ok guys check this out.I ran out of petrol(ok I am a girl!) and the yellow engine light stayed on afterwards.Hyundai said I would have to sell my soul to get it sorted but would be ok to run I t failed it's Mot on emission,but the local garage managed to temporarily fix the problem to get it through.The light came back on after wards-!!! So I did some research on Internet and here's how to reset it yourself-- Take off positive lead from battery,then turn ignition key on to get rid of any stored power.Then pump the footbrake(yeah I wondered why!) for about 20 secs.You will hear allsorts of clicking in the engine as ecu resets.Then reconnect battery lead!! Wallah !!!!
I went armed with this knowledge to the local garage(much to their amusement) and asked if they could reset the ecu,and they said a dealer would have to do it.I said well I know how and asked them to disconnect battery for me(their frowns got deeper by the minute).The rest I did in front of them,They were gobsmacked!!!!
They were amazed and asked me to call in a few days to tell them if it had worked permanent as they had learned something----so far so good!!!!
I f you have a computorised radio make sure you know the reset code for that as it may knock it off.
The ecu resets when you drive away.Now drives like a dream.

well if she ran it to long with no oil it might be locked up and might be able to turn it over if its not to bad. but you should still get power going to your fuel pump i would check all connection going to fuel pump and no broken wires. try even un plugging battery to see if there's a bypass
