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?

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?

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?

A dropping resistor is used with the stock Datsun EFI controller.

Dunno whether the Haltech needs it, and it may depend on the injectors you have.

Here are my A14E injectors:



And th dropping resistor

Champ, cheers

worked a treat didn't run the factory one just wired in a few resistors

Glad to hear you got it running!

at 440cc they will probably be 7mgte injectors

the haltech should just have the option of high or low impedance injectors. shouldnt need the resistors if its set up properly

Thats my drama, it obviously not right. it has spark and runs on "start ya bastard" but just wont fire under its own steam. if i run the resistors and low impedance setting will this cause a delay and throw out the dead time? don't think i was getting pulse at the injectors without the resistors. can i run them as high impedance and leave the resistors. no i haven't slept, delirious and i'm fresh out of ideas
