I have a 1991 Wrangler Sahara with 130,000 mi on it. 4.0 6cyl. 5speed
manual tranny. When the jeep gets hot it will not start. I can
"Crossover" the starter and get it started. I Can also push it and
pop it to start. I have done some research on the topic and see that
this can be a problem. ex, http://autorepair.about.com/library/faqs/bl031h.htm
What i am looking for is the wiring diagram for the starting system.
Does anyone know where online that I can find this diagram?
Thanks you in advance.

The part between the key switch and the 'cross over' part is called a
starter relay. It is located on the firewall at the end of the battery
positive cable. I would start by cleaning the connections on this or
just replacing it.

The other part is the key switch located at the bottom top of the
steering column.

You could hit either with that electronic 'freeze' spray to see if heat
has affected them but the relay is a known dirty connection trouble spot.
