Hi, all. I just discovered something that I thought others would benefit from. I had the dreaded "no start" condition on my 245. After working my way in the parking lot of different posibilities, I soon found myself in the passenger footwell replacing the fuel pump relay. I learned from others on this site to carry a spare. Well, the wiring going into the connector didn't feel right; and by the light of my cell phone, didn't look right either. I left the connector and relay "just hanging" there as I stated the car and drove home. The next morning with good light I looked again at the connector and noticed the insulation from the big red wire was severely worn through with just a film of material left covering the braided wire.
Apparently , over the years, this wire has been rubbing against the firewall where it is clipped, and was nearly worn through! I supect it could easily happen to other cars; the relay is supposed to clip on a hook thing there. SoI taped it up really well and bent the clip away from the firewall to keep it from rubbing anymore.
As I understand it, this red wire is the main power source to the fuel injection system and fuel pumps.

 

yeah, red wires are usually unswitched and unfused power, directly off the battery, or the 'positive terminal' which is right off the battery.
