Rob;
OK on attitude...Haynes and general manuals are OK to guide general repair work, but they do have only some and limited FI info, so the factory green manuals in conjunction with linked troubleshooting guide are really what you should work with... For example, the FPReg is functionally described and shown cut-away, so there would be no doubt as to connections...as far as adjustment...set that output and lock it there with jamnut...there is no reason to muck with it further...just assure dumpline back to tank is flowing to assure system circulation..a common failure mode is that FPReg gets bound up after non-use, and does not dump fuel back to tank, so pressure soars...!
If plugs are wet (not soaked!) and fuel pressure is constant, you're clearly getting fuel, and I did see that it starts but immediately (suggesting that Ign Sys is also OK), but then stops running, I have no explanation for this...yet...(but I'm certainly interested in MAP Sensor test results...!)
"Leaking Injectors" do you mean they are leaking fuel (NOT RIGHT!) or their seals to Cyl Head are allowing false air to get sucked in past...big diff, and not right either(!), but not quite clear to me! ...and that CSI should not flow ANY fuel after warm-up...then, it's strictly along for the ride...another common problem is a nonsealing CSI...its hell on the running mixture...and mileage...!
Good Hunting!
