Nissan Primera P12 starting problems

Hi Timeshock thanks for your reply.

No I have not been able to fix the car....

When I turn on the switch I can hear the gas pump sound.

The car crank but does not start.

Everything started intermittently. The car had trouble to start, after some intents it started.

Suddenly one day stopped, we took the car to the Mechanics. They suspected from the coils, 2 of them were changed like 2 months before the final fail.

Then came Covid 19 and the car stayed for 3 months sitting there.

They say that the problem seems to be the ECU, but the thing is that the Computer does not appear anywhere. I can't find the exact part MEC30-180 B1 2606.

I used a ODBII scanner and showed error p0335, I took out the CrankShaft Sensor and wen to a place where they test it and it seems to be ok.

I bough a small oscilloscope and "tested" the crank and camshaft signal which I think seems to me there.

When I decided to take the car out of the repair shop, they said the card started again. Then failed to start again. After a few days with the battery disconnected, the car started again at home few days after being unused, but just for a few minutes. I though it was something resetting, but I have tried to do de trick again but Since that moment It haven't star ever again.

I wish to find the real problem. The car have a sentimental value for me, I don't really want to say the reason in this public forum, but. I wish to be able to start it again.

A friend of mine helped me the other day, he found out that in the Coil there was ground and the positive, but something weird was that the signal pin had also 12volts + I don't think that is ok. What can make 12v+ present in the signal pin?
I have the manual too. It refer to disconnect the condenser hardness

1. Turn ignition switch OFF .
2. Disconnect condenser harness connector.
3. Turn ignition switch ON .
4. Check voltage between condenser

But I haven't found the named Condenser

Believe it or not. I have not been able to start the car yet....
