Hi, Me and Brian posted at the same time, he's a moderator. I thought he might have better info than me.
As far as the donations, I don't know much about that, I believe it will get your post looked at quicker.
Without a code or scan-tool data, it's hard to know where to look. I'd have to do some basic tests. I did ask about primary voltage at the coil connector. You said you hadn't checked it, yet.
If there is no rpm signal, Brian ask about that. You may not have any spark, no injector pulse, other than the initial prime, the pump may not run. I don't have your wiring diagram in front of me, if the pump circuit has an o/p switch in it, it is possible to have fuel pressure without an rpm signal. But the relay won't energize. I'll help anyway I can, but, you will have to do some of the testing.
I just wanted to add, if you have an injector pulse during cranking, then I think the rpm signal is present.
