My guess is that the plastic retaining tab on the injector connector failed so it was making intermittent contact. I went ahead and replaced the injector since I was in there, but I didn’t have a new connector so it’s got a zip tie bandaid that I’ll remedy on Sunday.
Ended up having to use the coil I had bought since one of the connector retaining clips broke on the coil side of that one too, and then a second one broke about halfway off so I’ll fix that properly when I do the injector harness work.
At least now I know exactly how to pull the intake and fuel rail now, and since I won’t have to remove the injector again I shouldn’t smell like gas after I do that work.
Crimping is the best splice method for engine stuff, right?
A lot of that plastic stuff gets brittle after so many years. Some recommend heat shrink connectors for splicing but I soldered a lot of wires, too. Some are against soldering but I did it a lot without comebacks. Solder and use heat shrink tubing, works in places where you can't get easy access.
The good heat shrink connectors will make a complete seal when you get them hot enough.
I started using gloves whenever handling fuel or battery acid after years of smelling like gas or diesel. I think diesel is harder to get rid of than gasoline. I use chain lube that has kerosene or diesel in it and I always glove up so I don't smell like that later.
