Alberto. You need to keep at it. When I first got the 707, I had a lot of trouble starting it. There were many times when using CTRL+E wouldn't even start them. Then suddenly. It all just worked, I get it started first time every time. You just need to get "into the grove with it" (I can't think of any other way to put it). Once you do that, it's great.

For encouragement, take a look at this Topic that I started when the 707 first came out. I was really frustrated because it just wouldn't start, no matter what I tried. Eventually it just "happened" and it was all worthwhile. Keep trying and suddenly you will just know how to start her up.

I had this problem with the Captain Sim C-130X too. Now I get it started first time, every time too. I persevered and got there in the end.
