PEH:

If the old style hand pump is bad, it doesn't draw fuel from the tank, just pulls it back and forth, and allows air to get sucked in by the lift pump. No way you will ever get it started until you get full pressure and decent fuel flow in the IP.

Most Bosch IPs have a restriction in the return fuel fitting rather than a spring valve -- the spring valve is usually in the fuel filter, not that it matters much. It DOES if you get the restriction in the supply side! The VE pump on the Volvo doesn't have a pressure valve at all, other than the restrictor on the fuel return -- the filter is on the suction side.

I've only tried to roll start my 220D once, and the hill wasn't long enough! Spent about an hour digging around (in the dark!) up against the exhasut manifold with a pair of pliers trying to jump the solenoid -- the neutral safety switch had just died and I stalled the d.... thing turning around after looking over a 190E for sale. Stupid.
