I have been flying my RV-10 (IO-540D4A5) for 2 years now with the EMS-D10 and the Injected Fuel Pressure Sender. Normally the reading is around 35 or so with the electric boost pump on, but lately it will spike to 99.9 and then reset to normal and then spike again. It is doing this the whole time while on final when I run the boost pump. Normally I get a spike when the electric pump is first turned on, but then it is stable, but now it is constantly going on and off with the 99.9 reading. Any ideas? As far as I can tell the boost pump sounds like it is running normally.
