Confirm this to me please.
 
I think I found out my problem with the injectors not running.

The guy who sold me the wire harness did not give me the resistor pack.
So I have the plug for the resistor pack but no resistor pack. Thus my injectors are not connected. right?

As soon as I buy/connect the resistor pack, my injectors should spit. Right?

If I'm right, this will be last you hear of me with my injection problem. I promise. :)

Thanks!

Yeah,

I have not be up to date with any of your other problems but if you have Low Imp injectors then you need the resistor pack.

It should be located in the front passenger side corner of the engine bay under where your stock airbox is located. It is a rectangular silver box.

Resistor pack info needed
 
I bought a wire harness and the guys that sold it to me did not give me the resistor pack...well, thats what I think.

I have the plug for the resistor pack but no resistors.

Would that be why my injectors dont spit?

Why would you start another post on this?

Yes, if you have low imp injectors then you need the resistor pack.

Now if you have high imp injectors then you don't need that resistor pack. I had to fix a similar problem with a project car I picked up awhile back. Car had 2 low imp and 2 high imp injectors installed on a low imp system. Replaced the high imp injectors with low and all fixed.

You might want to include your cars year and weather it's NA or Turbo.

Here is what it looks like

Need more info on your car: pre 87.5 has low impedance and post 87.5 has high. My car was a mess, it was about the opposite of yours... I had a harness with no plug, low impedance injectors and a resistor pack with nowhere to put it.

If you find that you do for sure need them, I'm sure there's someone on here who switched to high impedance that can sell the resistors or something. If not, just go the radio shack route and hard wire some resistors in the factory location. I cant remember what impedance resistors you'd need...

My car is an S4 N/A swapped to TII

Because you are not answering my question. This is not about low or high impedance. Its to know if this is why my injectors are not working.

Please read carefully.

If I have NO resistor pack CONNECTED on the wire harness BUT I DO have the plug to plug it, would that be why my injector do not spit?

Another way to ask this would be, if I unplug the resistor pack, will that make my injectors stop working?

To me its a logicAL ''YES'' Answer, but I just wanna be sure.

Thats all.

No resistor package means no 12vdc pwr to the injectors. Ain't a gonna work.

Unless you buy a resistor package and install it.

Or jumper ALL five wires of that plug together so the injectors will have power.

If this is a TURBO EM harness that was originally with THAT turbo engine you put in, then it PROBABLY has low resistance injectors and SHOULD get the resistor package installed on the plug INSTEAD of jumpering all FIVE wires together as I mentioned above.

The resistance of the inectors can be figured out without removing the intake manifold. With a meter, just ohm out the circuit from the PLUG for the resistor package to the small plug on the ECU. The series four wiring diagram shows which wire goes to which socket in each plug.

BUT what is REALLY being missed here, is that no one in there right mind would put a TURBO EM harness in a NON TURBO car. And the reason for this is, the EM harness mates with the FRONT harness with two ORANGE looking plugs above and to the right of the passengers feet. The pinouts for those two plugs are not the same for turbo vs non turbo.

I'm not sayiing it won't work, only that a lot of rewiring to those two plugs NEEDS to be made for it to work right. Plus .......did you noitce that you now have NO alternator plug?????? On the non turbo cars those two wires are in the EM harness and on the Turbo car it's in the Engine harness. Engine harness being the one that runs on the LEFT side of the engine bay, not the right side.

Anyway,the injector wires at the small plug of the ECU are in number four, and one is green, another green with white stripe, another green with black stripe and from memory the other is green with red stripe.

All the above made sense to Me and might make sense to others. Maybe not.

Here's the jpg's of the ORANGE plugs that mate the EM harness with the FRONT harness.

You can readily see where the Turbo ( ) harness is pinned different than the non turbo. Like I said before, those plugs can be modified to make it work, but jeeeez, what a mess. Some wires would have to be moved from the X-16 to the X-15 and two new wires would have to be run from the alt plug to X-15.

So no resistor pack means no power ot the injectors. So thats why they are not working.

This has all been taken care of. Thank you.

Seems to me it was about low and high as that is whatt Hailers said as well. We didn't know you had a swap from NA to Turbo until later. Always include that in the original post.

Either way glad it was figured out.
