1997 850 won't start, but cranks. Video included
 

I'm not sure what the problem is, I'm basic on cars, it worked for the first few days buying it but then it died. I replaced the battery, air filter, and fuel filter. There's noise coming from the throttle body and idk if that's normal. There was no check engine light.
I will try and upload video soon.
[click link for video] sorry it's too long for the thread.

Noise from the throttle body is normal, so that's okay. I didn't listen to the video, I admit it.


You need to check for spark and fuel pressure. There are some common problems that affect these cars, probably very minor. My dad would ask if you're out of gas.

at the end of the fuel rail there's a shraeder valve (like a tire) that you can connect a fuel pressure gauge to. Common causes for no fuel pressure include bad fuel pump, bad fuel pump relay, bad fuel injector relay, bad pressure regulator (kind of hides under the intake manifold- it has a vacuum line attached. Sometimes replacing the battery can put a car into security mode (which can be reset using the key fob to lock/unlock the doors a few times in a row).
