E30 runs for 5 seconds then shuts off......can't figure out what is wrong,please help

Hello, I am new to the forum. I had purchased a 1987 325e about 3 months ago and I ran into this issue that I can't solve. The car will run for a few seconds then completely shut off, it doesn't matter if you hit the gas or not, it will die no matter what. The problem began when I cleaned out the vacuum lines and the throttle body. I cleaned the throttle body with carb cleaner.....one of the vacuum lines that goes to the ICV was completely packed with dirt and harvest been restricted. I put the vacuum hoses back on and reconnected the throttle body and the car hasn't started since. This has been going on for about a month now and I can't figure out what is wrong. I replaced the ICV,plugs/wires, the alternator, the DME relay. The car gets spark and fuel, I am completely stumped. Does anyone out there have any ideas? Any type of advice will help! -Evan

Did you get both the throttle position sensor and AFM plugged back it?

Thank you so so much for your reply! Both of the sensors are plugged in and seem to be operational. That is why it is so strange that it had stopped running at that instant. I do have a small crack in my intake boot but that was there before. I will show you a picture of what was in my vacuum line if that may help. Could the ECU have long term fuel memory and not be able to run without this blockage?

The ECU self-adjusting range isn't big enough to prevent it from running after cleaning the breather tube. I'm pretty sure you're fighting another vacuum leak, or the crack in the intake boot has worsened considerably. You really shouldn't try running it with ANY leaks in the boot. It will run lean, and that's a much more serious condition than running rich. Burned valves and pistons are a real possibility.
