Apologies in advance if my search skills are just failing to find the information I need (I can find plenty about the ALH) but I'm trying to diagnose my no-start and at the moment I'm suspicious of air in the fuel system.
Brief background: Yesterday after I drove home I pulled the timing belt top cover just for a quick visual inspection. All looked good, put it back on and didn't bother starting the car again. This morning I started the car, it ran for less than 2 seconds then died and hasn't started since.
My first thought was that in pulling the fuel lines to the side (gently) to get the TB cover out that I'd somehow caused the system to lose pressure and fuel had drained back to the tank overnight. I was about due for a new filter anyway so I swapped the filter, primed it with a MightyVac...still no start.
So then I tried priming the injection pump by disconnecting the return line that goes to injector #4 and connecting the MightyVac to the nipple on the pump. I can get fuel to come through, but only with a LOT of pumping (it doesn't hold vacuum really at all) and the air bubbles are constant.
Should I eventually see a steady stream of fuel with virtually no bubbles, or are bubbles typical? If I shouldn't be seeing bubbles, then I guess I have to do some more troubleshooting to figure out where the air is coming in from.
