Hot Wire Coil Pack?

[porcelien]

Can you run a jumper to the hot wire that goes to coil pack in a 1992 3.3 without causing damage to other components, from feedback? Have done so with regular coils on many occasions through the years, when I've had hard to find electrical problems, but don't know if it will work on a coil pack.

Noone wants to jump in on this eh. Maybe this posting will move it back to the top of the heap and someone will have an opinion

I will reply, the coil pack is tricky you need to be certain which wires you are grounding & connecting power to. There is always a risk of blowing out the electronics that control it so it should be done out of circuit & with a diagram of the connector to be safe.

The wire I want to connect to is the 12 volt input wire. I just want to hook it up when it quits me and see if it starts. Then I will know for sure if the problem is in the wiring or starter relay ahead of the coil or if doesn'work, the problem is in a sensor after the coil. A test light would tell me the same thing, but won't get me out of the middle of traffic, when it stalls.

You have to be certain by diagram that you are connecting to the correct wire. Check the connector itself for corrosion or a weak wire.
In another post with the same vehicle he checked the coil pack again & as it was checked the 12v wire came off in his hand. He is splicing a new connector as his was intermittent as well. It seems farely common on these

The only problem was that the wire that was broken on his was the red wire, while the dark green wire with the black tracer is the b+ wire.
The red wire would cause 2 cylinders not to fire, not shut down the whole thing.
