Kenny K and Ken L both replied to my query about cutaway renderings in factory manuals regarding the chewing off of a small four wire harness on my 2000 4-cylinder manual transmission Ranger. I cannot see anything it would reach. There is a pocket in the tail shaft that would hold the speedometer gear in older days. But this pocket is closed over.
I used to be a "Goodwrench". GM manuals not only have full schematics, but another section has cutaway drawings of actual harness routings. This helps in locating possible abrasion related shorts. That is the kind of info that would clear this up in 3 minutes.
Additionally, I noticed it won't run. Cranks fine. I listen and can hear the fuel pump relay cut off 2 seconds after twisting the key. I also hear the pump whine quietly, then cut off. Depress the fuel rail Schrader and it does not squirt. My next test is to pinch the fuel return line to force a rich condition to see if the pump actually is pushing fuel or just sounding impressive.
At first, I thought the harness might have something to do with the fuel pump. But it is chewed off by the driver's side tail shaft. Not near the tank. So, the pump might be an unrelated issue with conspicuous timing.
I'll see what I can find out tomorrow. Maybe some pics too.
