No crank no start

With the new range sensor in, the gear selection lights up the correct position now but still will not crank. You had said before about the direction the signals go to tell what to do when. Since I still do not have signal to relay pin 85 is it the TCM that tells the PCM that it should ground or vice versa. If I understood it correctly I think it goes from TCM to PCM, if that's correct how would it be tested to see if it can be narrowed down to one or the other or a wire in between. So, if it is supposed to go to the TCM from wherever what wire should I check to make sure it is getting continuity through that wire? Then if I have continuity through the wire at that point where do I check to see if the TCM itself is receiving that signal? Then if the TCM is receiving that signal which wire would I check to see if there's continuity to the PCM? If I have that backwards and the PCM does not get its signal to ground from the TCM then what direction should I go then?

I have not been able to get a hold of my neighbors scan tool but when I tried to check for codes with my cheap-o it said there was no link. It powered it up but would not link.

Update: Would have posted sooner but the throw out bearing/slave cylinder on my 1993 Jeep Wrangler went out and with my luck it is the one that is inside the bell housing instead of outside and I had to deal with that first. But on the van it was the PCM.

Hey Steve, are you thinking there is a possibility of a short etc somewhere that caused the PCM to short out? On the Jeep I went ahead and did the clutch kit rather than just the slave cylinder. Like people say: while you are in there might as well do the kit and inspect the the rest. Only problem is it seems like there is maybe a design flaw or something on the slave cylinder, no matter which brand, because they only seem to last about five to seven years. I had replaced it in 2012 and on average drove it approximately five to seven hundred miles a year. I am thinking about maybe doing the conversion to an outside cylinder but from what I understand you have to kind of scrounge up the parts.
