Super VXer
Bart, just a heads up; I'm like you and I want everything that I put into the VX to be standard Isuzu issue, but Merlin want's something like $150 for the FPR whereas the one I got from NAPA fit perfectly, works just fine, and only cost $60.
Just sayin'.....

Hmmm, yeah. Perhaps I will go that route. What brand is it? Napa Gold or something else?Originally Posted by MSHardeman

Only after I swapped out injectors to have them professionally cleaned.
Its' pretty clear to me that fuel pressure has to drop as the car sits overnight. When you do a key on, that provide the fuel pump time to repressurize -- which cures the delay. Or, if it doesn't sit very long, it doesn't have time to lose pressure.
I actually don't understand how pulling the fuel rail loose cause my particular issue. I tried a second set of injectors with no change. Plus, running fuel pressure is where it's supposed to be -- which implies I did no harm to the FPR. I did note the same poor condition of the vacuum line that drives the regulator. So, I installed new vacuum line from stuff sitting in my garage. (Did this before measuring FP).
New viviton injectors seals were installed both times. The second time I took extra time to clean bungs in the manifold and rail.
I don't smell gasoline in the morning -- and you'd think this would happen if the fuel was losing pressure externally. These days, I think most fuel systems hold fuel rail/lin pressure thru a check valve built into the fuel pump. Changing injectors shouldn't affect that.
