Welcome to the forum.

I'm sorry that your car won't start. I love E34's, and I'll try, along with the other people at this forum, to help you discover your issue.

I've got to start by telling you that a "stomp test" is about as useful as a magic 8-ball. Sorry.

Let's deal with the new MAF first: Did you buy an OEM part at a quality BMW specialist supplier? If it's not made by Bosch or VDO/Siemens, you should return it.

Now, on to the no-start.

Step one is to see whether you have spark. Step 2 is to see whether you have correct fuel pressure, step 3 is to see whether you have fuel injector pulse.

If you don't have these three things, even a brand new MAF in a white BMW labeled box isn't going to help.
