It is running though, just got bleeding to do and the battery is drained.

Otherwise, success is at hand!

New problem.

I can get engine to crank, it runs, and then dies after 2-3 seconds.

Acting like there is an air bubble, does the same thing on both the normal tank lines and running off of a bottle.

Ideas? This is starting to wear on me

Fuel filters maybe not completely filled? Air in the IP or injector lines? Have you tried cracking the lines on top of the injectors and cranking for a bit to get any air out? Timing possibly off a bit? Keep going with it, you are almost there, it is definitely showing signs of life

Cracked the lines, they are well bled, multiple times, individually.

There was an air bubble that persisted in the pre-filter at the boost pump, I bled it out.

When its running, timing sounds perfect, the ONLY culprit I can think of is air, because it cuts off so suddenly, and is so eager to catch once its bled.

Got any recommendations for bleeding the IP?

Also, why the HELL is a 1000 CA battery so easy to kill? Maybe I need a new starter?

have you pushed the accelerator pedal down when it runs? pushing it down slightly to raise the RPM's should help bleed out the air.

It doesnt sound like air any more. Is your lift pump good?
I think you said b4 that you had checked the banjo bolt/ pres reg.
In the past, I have run a motor on wd40 in the air inlet. Get some one to spray wd40 in the air inlet while you crank, once it starts keep the wd40 going & try and rev the motor up ro say 2000 rpm & see how it goes for say 30 sec.

I suspect it a little.... unfortunately I don't have an alternative, I may go to the junkyard tomorrow and grab a lift pump.

Other option: Could I install an electric diesel fuel pump and see if it helps?

Is it possible that one of the connections is not tight, or you have some cracked/deteriorated rubber line. It almost sounds like you are sucking in air at some point. Might want to check the seal and O ring on the secondary fuel filter. Hope this helps

Will do, I'm picking up a new lift pump and an electric fuel pump to bypass the lift pump if it is weak tommorrow

You could if you have one handy.
Army did a good write up on rebuilding a lift pump. Worth a read !!
Running the motor on wd40 does work, I have done it.

Me too, me too. I'm not giving this Mercedes up, may not be as easy as my VW, but has been worth the challenge.

She WILL live!

Broken record.

The o-ring on the secondary fuel filter fixing bolt and the hand primer pump are two common sources of air leaks.
