Hello I have a 1995 bmw 525I E34 that won't start but cranks I preformed the stomp test and it gave me code 1215 so I changed MAF sensor and still won't start any Idea's would help.
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.
How familiar are you with cars? We need to know your experience level, to assist you adequately.
