i'm not sure what they are off but they flowed at 440 and fit into the factory(?) manifold the comp says it's picking up trigger and home every revolution so u would have to assume that its sending it to? whats a dropping resistor and is it internal or something that should be in the wiring?

The factory A14 injectors are not connected to earth, except through the wiring harness. But they use a dropping resistor.

Your question seems more about the Haltech controller. Which injector exactly are you using?

hi, i'm having trouble getting my injectors working on my A14, the car has a Haltech platinum sport 2000, the injectors have been flowed and are low impedance, i'm getting signal to the injector and 40psi fuel pressure at the rail. But no squirt. i was struggling to get spark from subaru coil packs and the fix was a 2uf capasitor (spelling is fingered but u get the idea) earthing the row of packs, injectors switch earth so that wouldn't apply exactly the same way. should the injectors or fuel rail be earthed as well as signal wires? i'm stumped any ideas?
