Thanks. I've actually been through a bosch ve a few times. I'm pretty sure my pump is fine, but that I have some sort of either pressure leak out of the top of the LDA, a split diaphragm (although I could see any issue with the diaphragm when I looked at it) or there is some other system on this particular pump which isn't hooked up properly. It has an odd ball thing on the side of the pump that looks like it should create a high idle, but doesn't seem to be hooked up to anything. It's right above the cold start device. I have nozzles on the way so will rebuild the injectors and keep poking away at the pump.
