ECM question

I'm trying to hunt down a starting problem and am looking to check to see if i'm having a crank signal. I want to pull off the ECM harness and check the pin that should be carrying the signal, only I dont know what pin it is. Anybody have a wiring diagram they could check or know where i should be looking? Thanks.

btw, just to make things easier, where is the ECM located? I'm assuming somewhere around the instrument cluster but i'm not quite sure.

Have you checked to see if the injectors are spraying any fuel while cranking? Also, you may want to get some sort of scantool to see whats going on.

Well there's no spray while cranking, I know a pretty good mechanic who said he's going to look in some manuals and try to give me a hand with it.
