Hi Dave
I carried out that test on the pump on a previous post,you can only view it with mediafire.It is very similar to your first capture the rail pressure goes from .5v up to 4.5v.
The Delpi rep said it could build up the pressure while doing that test while no injectors was using fuel ,but the problem arises when the pump has to maintain max pressure while the injectors are injecting fuel.
As for the question about their diagnosis of the injectors I don't know but just in case I bought the pump directly from Ford ,there wasn't much of a difference in the price.
Out of curiosity I would also like to know how Kevin /Dave 01 knew it was a pump .Again thanks for all yer input.
