[V8] Infamous V8 No Start

[Ed Kellock]

I haven't seen mention of it so here goes..

ECU temp sensor, rear of passenger side head.

The 5spd that was for sale here in the Spring a year ago (for 1500!)
was plagued with this.  The owner would run the battery down and
change plugs and finally threw in the towel (not a DIY'er).

When my buddy and I went to look/buy, it took us a good 30-60 minutes
to get it to start.  After the purchase, a new temp sensor fixed it
right up.
