As the title states, my secondaries wouldn't come online, I tried everything and it was simply a bad resistor pack OR the wrong resistor pack. I don't know if this (in the pic)was the one off the n/a or the turbo parts car, I got them mixed up during the swap. but they have to both be the same series (both cars were s4).so i wouldn't think it mattered?

86 and early 87's were the only ones that even had the resistor pack. Also, I'm almost certain that they are the same. Anyway, it is the same for all 4 injectors so if it was wrong it would affect the primaries as well. I guess the other one was just bad.

Ahh I see, thank you for clearing that up Sideways7.

awesome to see you found the problem!

I had the same issue with my first 7. Haynes (and perhaps the FSM) as the solenoid resistor. Pulled one out of an 86 and fixed the issue immediately.

awesome that you fixed it, i'm having the same problem i was gonna swap my harness but im gonna try the resistor pack tomorrow

hate to burst peoples bubble.
but i replaced my passenger side harness and it fixed my injector issues.
just ended up causing a different fuel pump problem.. but thats off topic lol.

Just fyi it's been awhile now.. 4 or so months and the problem did not re-appear, replacing the bad resistor pack was the real deal. in this situation
