No start

[albee9]

Ok here is what i have 2002 Town & country 3.8L

I can't seem to find the no start problem .

I can get the van started by way of the relay jumping pin #87 and pin #30.

it will start and run but will not start with the key only.
I checked pin#86 with ignition on and i get 12.04 then I checked #85 and did not get any thing.

yes i did change the relay before got deeper in to it .

what is a fool proof way to find the problem.

I'm leaning towards bad ground
