hyundai coupe 2001 problem

[ninja123]

Any hyundai experts out there that could give me a little help?

Customer lost keys.

Cut new key to code to gain access to car.

Found aftermarket immo on and a cobra alarm system.

Removed both units and re joined original wiring.

Tried several times to program key but car wont start, no fuel pump running and no spark, no central locking from door lock too.

Found 2 wires cut in drivers kick panel, 1 blue and 1 pink/white, joined to same colour wires in pass side kick panel, and thre is a small relay unit in pass kick panel that was unplugged, and these 2 wires go to this (dont know what it does).

Still same :( tried limp start but no good, im not sure if this is a key programming problem or other?

Anyone know what immo symptoms are, does immo cut fuel pump too?

Any pointers or wiring diagram would be brill.

Thanks in advance, ninja

You will hear the pump cut in and it will spark once if the immobiliser is on. Cheaper to replace Ecu, Immobiliser and key set from another car.. Try hear for manuals Hyundai Coupe F2 Evolution (http://www.newtonnet.co.uk/coupe/#Service_Manual)

sorted this bag of shite now, apparantly, when these are fresh off the boat, the dealers fit a cobra alarm system, and do some major loom hacking in the proccess.

There main problem were the fact that one way diode were not put in the system and they back fed blowing the Cobra unit
