The ECU only turns on the FP relay when it thinks it should. Just
because the key is on and the ECU is working doesn't mean the FP should
run. It only needs to run when the engine is turning. The ECU turns on
the FP relay for a second or two when the key is turned on but after
that it only runs the FP relay if it thinks the engine is turning.
