Peugeot 405 GLI 1.8 with spark in the 4 spark plugs at the same time and does not start

He approaches nothing and I don't start anymore, he was changed coil and rpm sensor, sparkled at 4 spark plugs at the same time, everything is seen, relays injectors, gasoline pump, everything works but still does not start.

You already checked that distribution is not the problem.

controls that it is not the cataloger that is struck greetings

He made him review with an electrician, apparently everything is in order, just that he mandates sparkling at the 4 spark plugs at the same time, it is Nafta and GNC. A diagnosis was made and does not mark any fault, I still did not connect to the Scanner, I want to get all the doubts before paying $ 1500 to connect the scanner. If you have any idea what it can be, I would appreciate it very much. I also check the distribution, apparently everything is in order, but they told me that this car has a key on the crankshaft pulley and that it is cut and leave point, but I do not see because I should throw spark at the 4 spark plugs at the same time, if it were so it would only make false explosion or start it would fail, the truth is that I am already crazy, buy an ECU to try if that was the problem but there is still the problem.

I lack the year of the car, here you have to be very specific.
In my program not to apostle the 405
What is the ECU and what version?
