Freelander 1 throttle pedal

Hello.
I know that question has been up here several times and i had got a lot information from there but i have question. I it possible that faulty low pressure pump can cause malfunction on throttle pedal?
Long story short. High pressure pump had fuel leak. I fixed that problem and when i was bleeding system i noticed that fuel line before high-pressure pump dint had any pressure. Soon i opened bleeding valve pump start sucking air in. Same time gas pedal stopped working. it do not respond any way and engine starts after 10sek when you start cranking. My gut say's that can cause because low pressure pump but i need conformation.

I'm assuming you have a FL1 TD4 as talking about low and high pressure pumps.
The TD4 throttle pedal is electronic so it sends a signal to the ECU. The ECU will not let the car rev if there is something badly wrong but it's not likely to be the pedal.

so far no results. only news is that it has only one pump and main pump should suck fuel in but system gets air in somewhere.

question. can it be result that throttle do not work because that?
