Whole left Bank not firing.

Problem: Car starts and idols fine. After a couple of minutes, the left bank will stop firing. If i pull the main plug to the left bank coil packs, the car will not idol any differently, Right side, it will die.

Things I've Tried: I tried switching coil packs, the whole rail from one side to the other. I disconnected each one and plugged them back in. I checked the actual connections for any kind of arcing, etc. I checked all the plug wires, etc.

Question: What ohm or volts should the Main plug going to the coil harness give off? How do I test it? I don't know to much about electrical. I can change wires and replace but I don't know voltages and what everything should have. Anything would help.

Re: Whole left Bank not firing.

turn the car to "on", but don;t start the motor. one at a time test for 12v on the pink wire. If you are holding the plug so that the pink wire is on your left then the wires read from left to right - 12 v power supply, Ignition control from pcm, reference low, ground. if you are getting 12v on the pink wire then all of your fuses are fine. If you do not have 12 v then check all of your ignition fuses and try again. if you still don's have 12 v then your problem lies elsewhere. If you are still having issues just let me know, I have been though this twice.
