New project, new problems. I picked up a 1984 300D project/parts car on Friday and I am having trouble getting it fired up. I pulled all the glow plugs only had to replace one of them. The relay is working correctly. I then tried to bleed fuel lines. I loosened the hard line fittings at the injection pump, held the throttle wide open and cranked it over for several minutes and did not get any fuel to leak out. I then changed both filters refilled the canister filter and tried again, still no fuel out of the hard lines. Thinking I might have some plugged lines or an air leak I eliminated the fuel tank and ran the supply and return line to a small tub of fresh diesel. (Like diesel purge set up.) After cranking for a bit with this setup I was getting some fuel coming out of return line but it was barely coming out and when I plugged the return line with my finger I felt no pressure build up. Even after cranking for over a minute. The old style manual hand pump leaks like a sieve when I pump with that and is useless, however, it does not appear to leak or suck air when I tighten it and crank the engine. Not sure what to try next. Looking for some help. 1. Would a bad lift pump cause this problem. 2. Does anyone know how much pressure or volume I should see at the return line? 3. Could the leaking hand pump this problem.
