I finally found my problem... Fuel injector wiring question

[the_dingman]

Success! With a little playing around with a multimeter today, I think I found the reason my 1st injector is not firing.

Service documents online told me that all 4 injectors fire simultaneously, meaning that they must all be wired together. I ran a multimeter across the pins on different injectors checking for continuity. Any combination of pins from any injector would show continuity, except one of the pins on my 1st injector, leading me to believe that that wire is disconnected somewhere.

Now, the question is how exactly the injectors are wired. One would assume that if they injector wires are showing continuity between pins 1&2 for the same injector that they might be wired together... But that doesn't make sense...

I'm not planning on tearing apart my wiring harness to find the break, or to replace it. I want to splice a wire from one injector to the first one, but I need to know how they are wired so I know exactly how I should run that wire. Wiring diagrams haven't seemed to help much... Any ideas?

I'm up and running again... Though I think I need an oil change, when I rev the engine I hear a nasty grinding sound...

Three months without my truck, replacing Spark Plugs, Plug wires, Distributer cap, and having my injectors cleaned, and it was a damn bad wire.

I'll stop clogging the boards now :

Congratulations! I hope I didn't steer you too wrongly when I suggested you get your injectors cleaned and balanced....just couldn't see you being better off with those cheap aftermarket injectors that you wanted to buy.

The injector cleaning was the best suggestion anyone made! I was amazed with simply how they looked after coming back, and so far they seem to perform much better (though I haven't been out on the road yet). I appreciate your help, and everyone else's too.
