Alfa 156 and emulator

Good evening to all, I have a Alfa 156 1.9 jtd euro 2 99 that I had to make a scodifica total. It is not the first that I do, but me time is creating problems, practically following the instructions of the emulator, in the process, 24c04, then I mount the emulator soldering, positive, mass, and the tails, cut the wire that goes to the c13 of the code and I put in motion. So far everything is ok. But if I turn off the car, look half an hour or so and I try to turn it on again, not even dead. If ex-l emulator, and the piecing, it works and starts up again, even if I turn off and power back up again, but after the pause no longer works. Has it ever happened to you? Unfortunately I don't have another emulator to do tests.

You closed the contact J4 on the emulator??

Yes, I closed, I do not know what to think, when in doubt, I ordered a emulator new.

then does not depend on the scodifica,check relay,rail pressure, and recovering the injectors
