Today was supposed to be Change the Fuel Filter Day; I did like the book says to release the fuel pressure-- I got an injector boot off, connected one side of the injector to gnd and pressed a wire from 12V to the other, and was expecting to hear what the book says I should hear, some kind of hiss or something.
I got plenty of spark when trying to make a good contact by pressing my flimsy wire onto the injector tab, (never for more than a second at a time), but there was absolutely no other noise than the sparks-- no whooshing, no little hiss... nothing.
Well, nuts. Maybe I don't HAVE any fuel pressure; maybe the injector is bad; maybe you need to make a really, really, really good contact before the injector opens; maybe...?
I was pretty set on replacing the filter today, so I'll probably do that whether gas starts spraying all over or not, I'll just have to take care. But I thought I would post here in case you guys could think of something to try or something to do while I've still got that #4 injector boot off, (it was the devil to get it off of there, with that tiny clip).
