Lifted E30 V2

I should have known this would happen, but guys, for real. Avoid diesel BMW stuff at any cost.
Repairing and testing the pump cost more than the pump itself.
I have an $1,100 fuel pump, and it doesn't even look that cool. -
You can replace the heater valve with a bit of hose and a brass valve for cheap, or, disassemble the leaking one, remove the actuator, and cap it with a block off plate which will leave it always open.

I like the brass valve idea lol. Valve open in winter, valve closed in summer.

mostly yes, but, dont forget the windshield can fog to hell on a summer day in the rain. without the heat, its hard to get rid of that condensation. i did a couple of autox runs in the rain with my windows wide open so the windshield would stay clear when i bypassed my heater valve last year.

This past weekend I tried to get a video of the sweet smoke-rings that this thing blows. There was a lot of smoke, but no smoke-rings. Troubleshooting that I saw involved re-bleeding the fuel system and not much else. Waiting on the sage wisdom of a diesel elder...

Quoting for proof. Although I think I'm siding with you on this one.

The lack of confidence is saddening really.
My lack of time to work on it isn't great, but I have an action plan, and it all involves the Friday evening before the picnic, as that is my first available time. -
I have thrown in the white flag. Time to switch back.
Got more air worked out of the system but still doesn't want to idle or run normal, and then will frequently just rev itself up to 4500 or so and just sit there with no throttle input while smoking white (blue?) a whole bunch.
Either the motor is toast or the pump isn't working right, with my suspicion more toward the pump. -

selling the diesel setup then?
-
Sorry to see this. It was a great project idea and the running/road pictures were priceless.
Just a final 'evil voice in your ear' thought before others suggest it or to counteract any good advice and to potentially save @Bassboy3313 from himself. Perhaps consider one last rumbling, smoke belching, engine destroying ride through the e30 picnic grounds? If it's going to go perhaps go in style? We might lose the site for future picnics but could be worth it...

Where is that dislike button?!?!??!
Seriously do NOT let this thing defeat you, you were and are sooo close!
Maybe find a trust worthy diesel guy and have him look at it?
Maybe find a pump that you can convert to run instead?
There has to be somethign you can do other than give up.
I would be happier if you did do a cummins swap though vs another M20. (sorry not sorry)
-
Easy gentlemen!
I appreciate the words of not giving up, and you are all correct. I am not letting this win (just yet), but I want to drive the damn thing a bit, so I'm throwing the motor that works fine back in it.
I will be building a rolling cart to put the diesel on so I can roll it outside and play and try to get it working. I don't need a chassis for that, which is quite convenient. The more I think about it the more I don't trust the pump. That's the only thing that makes it work, and the motor isn't working right.There is a running driving 524td for sale that I may go look at, a spare motor wouldn't hurt, and there is a chance it has a similar enough pump that wouldn't require a whole bunch of wiring.
I have reached back out to Dave and Ivo to see if someone can find another pump.
For the time being I think driving it with an M20 is more fun than not driving it at all!
It does suck to be 3k deep into something that I'm taking out though lol.
