I did not get it started, but here is what I was able to do today.

I was able to check the larger fuel filter and it did not seem to have any air in it. I opened it slightly and primed it a few times and fuel came out freely.

The smaller filter gushed with fuel as I removed the end going into the primer, so that seemed good?no clogged line from the tank. I quickly reconnected it.

The glow plugs seemed fine. I checked all 5 and they are all getting power, and all showed about the same resistance. But I may not have done the resistance test right since I did not remove the electrical lead to each plug before testing it. (I realized this mistake long after I had stopped working on the car. wish I had thought about that while I was still at the car. It is not at my house yet.)

When I turn the key, the glow plug light on the dash comes on for 2-5 seconds. (I'm in Florida, and it was very hot today.) I tried to force the glow plugs to really get how by turning the key so the glow plug light would come on, and when it went off, I turned the key off, and immediately switched it over so the light would go on again. I did this 5 or 6 times in a row, and then I let the engine crank. It didn't seem to make any difference.

I also cracked the lines at each injector and turned it over about 3 seconds. I did this twice. There was fuel at each line. But I really don't know if it was enough fuel or not. It looked like enough fuel, but this is the first time I've ever done it. Anyway, there was definitely fuel at each injector.

The oil pressure gage gets up between 2 and 3 as I crank the engine. It is still climbing when I stop cranking, as I don't want to sit there and crank for too long.

I'm being told that even though the oil line broke, all the oil did not spill out.

As I crank it, it reminds me of trying to start a regular gas engine with very bad timing on a hot day. It would have two or three turns at a normal speed, followed by one or two slower turns, then back to normal for 3 turns, then back to a slower turn or two. Sometimes it sounds like it just about catches, but never does.

The battery was getting low, so I know that was working against me.

On Monday it goes off to a mechanic.

I didn't do a search for this, but I'd like to ask anyway.... ....

Does any of this sound like the symptoms of a ruined turbocharger?
