So I notice that the #2 cylinder decided to stop working, and everything checks out good on the right side(plugs, wires, coil, ect....).I get the throtle body off and start testing for continuance. All injector connectors are good which confuses me. So I take a minute to think and check them again, and now they are dead. Where did the circut go? What happened? now nothing attached to the harness has a circut, or at least Im not getting the BEEEEP that I was getting. The injectors themselves are beeping, and its a good multimeter. And I cant get a solid beep from the battery connection cables, all I get is a little half ass beep.

Could it be a relay? What would cause the multimeter to only momentarily beep??
This all started because the injector connections were bad so I spliced them into another area, which fixed it for about an hour. HELP

 

Are you checking continuity (beep)?
You'll want to check the injectors with an ohm meter from terminal to terminal
OR check them from a single terminal to ground (should read 12v).

There's an EFI fuse that governs a bunch of this crap at.. If it dies, I don't think your fuel pump will run. I *think* the relay fuse is under the hood, in that box of electrical junk on the passenger side.

Tell us what you spliced the injector connections into? I assume you connected them into another area of the same wires?

 

I spiced them into the finned resistor connected to the passenger side body. It worked for a while but now im not getting any beep from the connectors. Does that mean that no voltage is making it to them? The truck starts fine. It just seems wierd that it would suddenly not have continuance, where it did before. What would cause a momentary continuance(momentary beep).

 

you need to tell me how your volt meter is set up. "Beep" means absolutely nothing.
Beep could be 12v, continuity, who knows.. Does your volt meter have a display?

Need to be careful that you splice them into the correct side of at box... If you don't, it might run for a while but will eventually damage you ECU.
The circuit you're messing with looks like this:





Your injectors should always have voltage with the key in the ON position. That means they should have voltage between then connector (either pin) and ground. They should only show voltage across them when running.. With a slow (normal) volt meter this may show as a fraction of 12v... It's basically on/off very very fast.
