I made it home, with the Blurb, I think that the lift pump wiring has been a big part of my problems all along. From what I understand there are two circuits that control the lift pump, one is the glow plug relay (used to prime the fuel system) and the other is the oil pressure switch. I am thinking that the oil pressure switch circuit was never working, and that the glow plug relay circuit was, until yesterday (yup, it is tomorrow for me). This would allow for the engine to start easily using the lift pump, but then it would shut off and the injection pump would pull the fuel (really not good for the pump) to keep the engine running. Under decent throttle or towing it would act all kinds of funny because there wouldn’t always be enough fuel. On top of this, the lift pump circuit that uses the OPS could have randomly been working, making things even more off the wall. I am pretty sure that the computer isn’t smart enough to understand that there isn’t enough fuel, so no codes would be set. If the first part of the wiring had 12 volts, the ECM would think the lift pump was functioning even though it may not have been. I will have to do some more investigating, but I think I am about at my limit with the Blurb, I need to start from scratch, the previous owner did too many things that can’t easily be undone and I am sure that there are more wiring issues that are just going to get worse.
