<div style="text-align:left;">Thanks so much for the advice ,looks like the pump got back to work fine ,did test runn up to full throttle and no problems ,thanks again.</div>

I have faced this issue twice now...do you think the above solution would work?

More information please...

Hey Dave, well this problem came after 16 hours of problem free flight of my jetcat p140, last week this error started to come when I started my turbine and took it to full thorttle, the gsu showed pump parameters stored suddenly the engine flamed out showing "pumperr" i opened the filters in uat and the filter going to turbine from pump and cleaned it after the problem seemed to be solved, i did two flights after that with no issues. Today my first flight was ok, in the second flight the turbine flamed out after starting on full throttle with the same error. Now i have no clue what seem to be the issue.

OK. So check the wire and connections between pump and ECU. Also the throttle cable between ECU and Rx

Checked them, and they seem to be fine.

Is the cable between ECU and pump the one with very fine wires mixed in with bigger wire? If so order the new type with large wires throughout

Dave

i cant upload any picture here but it has all thick wires.

OK.

Try a complete log reset to clear ECU, Front Board and Pump Board.

Dave

Can you guide how to do the said log resets?

With power off hold the select menu button down, switch on Rx and wait. Ignore Learn RC, Ignore calibrate Temp and finally release when it says reset. follow prompts, do a learn RC and try it
