Well, take off the chip to begin with. Always start there.
Turning the key on, I'm assuming the WTS light comes on.
With the key on and fuel filter out, does the bowl fill up? That means the pump is on.
It could be a CPS. I'd swap it for a new one or a known good one.
After that, crank for a while then pull the HPOP reservoir plug. See if it has oil in it, fairly close to the top.
Could also be the UVCH coming loose or chaffing a hole in the wire insulation. I'd check them, pretty quick to check the connection.
