Replaced fuel filter (the engineers were so nice to put it in a convenient location). Jumpered the fuel pump relay and heard power going to the fuel pump. Still no good idle or rev. So, got a fuel pressure tester. Gauge is reading 35 psi (2.4 bar) with the engine not running. Currently doing a leak down test and its holding steady at 35 psi. Bad fuel pump?

After 10 minutes, leaked down to 32 psi. Releasing gas cap did not change readings.
