Check the EGI fuse.

also check that your resistor pack under the AFM is not dead.

If there is no voltage just at your secondaries, would you reccomend changing the injector clips first before anything else?

The clips do nothing electrically. They're just a metal snap that goes around the connectors.

Now the connectors themselves could cause problems but you should still be able to measure 12V at the black wire of each one even if the connector is bad enough to cause a poor connection. Honestly from what I have seen, 90% of FCs should have their injector connectors replaced regardless of whether there is a problem or not.

Well that would have been important information to tell us at the start...

Does the main EFI relay click when you turn the key to IGN? Check the power pins at the ECU for 12V as well...Oh, and did you check that EGI fuse?

Turn the Green **** three times to the left and pull up. That will fix it.

I have no knowledge of any green ***** in an FC, i'm pretty sure he's just making a joke post.

Are you sure you didn't switch the injector wires? That would seem like the obvious problem.
