Welcome to the forum,
This forum is full of great looking trucks; packed with great mod ideas and there are loads of knowledgeable and experienced people here.
You might try disconnecting the battery cable and leaving it off for about 30minutes and re-connect. When you recharge a completely dead battery, often the computer(s) start up at an improper voltage and have issues. This full reset may help. At least it doesn't cost anything and will rule out that possibility.
AND - We all like pix! Got any to share?
Enjoy the Z!
