ANSWER: Hello -

I am sorry, I need to verify. When you say pressure number 2 is that the tachometer? The RPM?

QUESTION: the RPM >>> ^_^

Answer
Is your check engine light on?
As you accelerate, is it missing? or vibratinig?

When you checked your fuel pump, what pressure was the fuel in the line? PSI?

If you answer these questions I can give you a more accurate diagnostic, but right now it sounds like the fuel pump, or a defective coil in your ignition system.

Hope this helps -
