Or are you saying that it initially starts out at 2 or 3 psi and then, after a few seconds, goes to 6psi and then holds there? The first is abnormal, the second is perfectly normal.

With the key in the on position (not start) and e-pump off, my initial pressure is 3 PSI, but then, after engaging the e-pump, the pressure goes to 6PSI, as it should. This was the case BEFORE I started seeing pressures of 9PSI. (so the latter of your two possibilities) steve
