well this is my first post here.

I have huge problems:

1. No spark. Coil does'nt get anything. Recently I replaced all the sparkplugs and the cables. I know that my catalytic converter and my oxygen sensor are dead. Could it be the bell housing speed sensor? Where is it located and how do i check if it is dead?
2. And I'm not sure if the AMM is still working (how do I check if it works? I could try to find a used AMM but how do I check if it works without my car?)
3. Let's say that the oxygen sensor and the AMM are fried. Should my main fuel pump stop working? It is now wired directly to the ignition key.

Thank you big time.
