Crankshaft sensor location?

I bought a 93 grand am and put a timing chainin it and it won't start. It has fuel pressure a new crank sensor checked the coils checked the injector new plugs and fuel filter. It shows no engine codes any sugestions?

19 Crank Position Sensor Fault, Runs when it's cold but dies when it warms up, replaced a lot of sensors don't know what else to do.

Well The module that under the cover, I already tested it at Auto Zone and it ran fine, I've heard you have to put some kind of a grease between the module and the cover. I was gonna try to replace oxygen sensor cause it didn't read on the scanner.
