Only thing I can think of off-hand is to check the fuel selectors (between the two front seats in the cockpit) and ensure you have selected at least one tank with fuel in it.

Hi Robbie,

Check to see if the fuel pump circuit break is in. It's located under the fuel pump switch, 4th c.b. from the left.

Btw, welcome to the A2A forums.

Hi:

I searched all of the fuel pressure issues for the A2A Comanche and I have not been able to get the pressure to rise. Here is what I did:

Prepar3d V4.5

1. Uninstalled A2A Comanche and reinstalled.
2. Removed ChasePlane
3. Restarted Prepar with a new config and ran the opening default flight and aircraft
4. Changed to the A2A Comanche
5. Checked fuel tanks as both full
6. Started cold and dark
7. all switches off
8. turned on master battery (Red toggle)
9. turned on fuel pump which is heard running but no movement of the needle
10. Started via auto start and the Comanche started right up
11. Switched off and then started cold and dark and the fuel pump gauge showed movement. The next start, the gauge did not respond. The Comanche does not start without the fuel flow.

I have had the Comanche for awhile and really did the Ctrl E to start. I may have never noted the problem.

Thanks for the help.

12. Autostart produces 5 psi fuel pressure. If I immediatley go to via Shift3 from Auto-Start and the Cold & Dark, the pressure is 3 psi and gradually falls to 1 psi while toggling the yellow fuel pump switch on and off.

I have had the Comanche for awhile and really did the Ctrl E to start. I may have never noted the problem.

Thanks for the help.

Hi.
You did not mention the position of the fuel selectors , in cold/dark these are OFF in auto start with ctrl+E these would turn on , the valves are on the floor between front seats.
You should only uninstall/reinstall as a very last resort , as it can do more harm than good , and could if you forget to do a clean uninstall/reinstall prevent any updates from being done.
ALWAYS search or ask in these forums first , someone on here will know the answer .

Thanks a million!!. Funny I did search and saw the other response to check the fuel to be on and thought it was the fuel selector vs. the fuel on between the seats. If you did not respond, I would be still spinning my wheels.
