Sorry bout that, this is why I should not stay up all night on prepware and trying to answer posts, but anyways.
A delta P light is a light commonly found on jet aircraft which warns of impending filter bypass, is is run via pressure differential not out put pressure, therefore a failing pump could not cause it.
You're pump can be tested by hooking up a fuel pressure gauge, the valve on the housing makes a good place for it, sorry but I can't remember how much pressure at what RPM off hand but know that it's at least 7psig at 2000 rpm.
Yes, a bad sensor could cause it to light up, as could a short.
Have a good one and report back, I'm going to bed.
