I have a TJ Magna and my issue is that sometimes on start up the engine will fire up and then it immediately dies and does the same for about another 3 or 4 times.Then it will start and run fine,but if it dosent start up I have to unplugged the immobilizer under the steering wheel re-connect the 3 plugs and then the engines runs again.
Any advice on how I can fix this?

Was going to suggest your battery may be dying and you should check it - but with the immobilizer process I'm now not sure.

The battery is still very good,I have read that this problem can be fixed by soldering wires on the immobilizer but cannot figured out which ones they are

Try the aerial around the ignition barrel, thats what is was on my TJ

This might be it
