I believe there is a dark green wire with black tracer at the pump
relay. That's the main power wire for the pump. It should be hot when
cranking. Is it? You may have an initial prime for a few seconds, with
the key in the on position, engine not cranking. After that, the
computor will kill it, unless there is an rpm signal, you can't get a
rpm signal without cranking the engine. If it is hot at the relay,
check it at the pump plug, if that's ok, check the ground. If it will
spin with B+ and a ground outside the vehicle, it should do the same
thing on the vehicle. hmm
