Hello Dave
I am cpying my email response to you:

Can you make sure the following are checked:
1- Propane line and fuel line not mixed
2- Pump start voltage is what your test run sheet indicates, menu 41, or perform the following test whereby you disconnect the fuel line, go to the test menu,
run the pump. It is set to 1V in the test menu, reduce the V until the fuel
stops flowing. Return the value to 1V.Make sure the fuel line dumps in a
container. Go to menu 41 and change the startup voltage to the value observed
plus 0.05V or plus 0.1V. It could be that too much fuel is flowing on startup.
3- Perform a calibration run menu 42
4- Calibrate temp probe menu 73
5- If all else fails do a system reset menu 99
6- Check that the temp. probe was not dislodged during shipping. Slide cowl and see,

Regards
Peter
