Also, you don't want dielectric grease on the metal contacts themselves. You want it around the seal of the plug, not on the contacts. The grease itself is an insulator.
I'm curious, how did you check the injector to verify it wasn't flowing?
First thing I would do it stick an ohmmeter on it and look at the resistance across the injector. I would imagine somewhere between 5-50 ohms. Then I'd check voltage coming to it during start up to see the "pulses". If I've got voltage, but no squirt-squirt, bad injector. If the injector is pulsing but not squirting, its clogged. Either way, new injector.
Thanks y’all! I took the throttle off and felt inside the boot and it wasnt wet. I then removed the injector from the boot and turn the key on and nothing sprayed.
idk how to test for voltage. I assume ground one lead and test one on the prongs for power?
