I have made a smoke test and I found a small leak at the fitting from intake manifold to brake booster.I will fix it, but I dismantled the entire intake to be sure there is no other leak betwheen intake parts.I am not sure if that small leak can make the car to not start.
When other person is cranking, I was trying to depress the air plate a little, to see if the engine will run...and there was no change...that is why I am affraid that this small air leak will not solve the problem.Also, today I have checked the fuel system again, again checked system pressure, lower chamber pressure, injection valves are new, and when fuel pump is running, if I depress a little the air plate, I can hear the injectors scretching..so there is fuel in cylinder.

I am waiting for the intake manifold gaskets, and I will put back together all parts and test the cold start again.

But I am still thinking what else could be if this will not solve my problem

Thanks.
