Chrysler Repair: 96 Chrysler Sebring Conv 2.4l Help, chrysler sebring, head gasket

Question
Hi I am trying to fix my 96 Sebring Conv.. I just last week changed the head gasket and other gaskets with it. it worked great for about a week. though the passanger side motor mount is bad... Now i am having a problem i cant figure out. All the guages are out and the abs light is on. i did a code scan and found these codes
P1698
P1784
P0600
P0731
and
P0350
p0351
I know what they mean i just am not sure where to start and if they would all be related to the PCM fualt code p0600 or if its the TCM I cant afford to not have my car but I also cant afford to take it to a shop or dealer... Is there anything that could help me here???

Thank you for any help

Answer
Hi Chris,
Unless you can find something wrong with the plug or harness at the pcm it certainly would appear that the place to start is with a replacement for the pcm. It appears that the other codes would be explicable if the 0600 were valid. Even the tcm code can be explained by a bad pcm.
