Oops! you said all coils are working except no spark on cyl. #2. you need to test the power circuit for short or broken wire. refer to engine control manual.

I thought disconnecting the positive terminal from the battery was to reset the ECM, but you are disconnecting both the positive and negative and then touching them together? Wouldn't that short circuit the electrical system or something?

verify you soldering job again. just disconnect negative batt. cable for 30 minutes, its long enough to erase the trouble code. when disconnecting batt. cables, always disconnect the negative cable first.

03 altima 2.5, replaced head. Now no spark. Checked all wiring that I unplugged. Looks good. They got engine really hot. Cracked head, exhaust was full of water. Any ideas?

Todd Mousel - was this a running engine before you replaced the head? I assume this was a DIY project. I also assume that you followed the procedures setforth in the service manual.

Now you have no spark in one ignition coil or on all 4 ignition coils. If no spark on all coils, Check Timing.
