DrDoom - after relearning the ECU and doing a start, I got the same results. So I called Bob Wilcox at JetCat USA and he asked me if I had installed a filter between the UAT and the turbine. I did, so he told me to remove it and try again. It worked perfect after removing the filter.

Usually in line filters are installed after the fuel pump, but on a P90 RXi the pump is inside the case and thus the filter I put on was installed before the pump, on the suction side. A lot of drag for the fuel pump.
