JK Electrical Code P2122

[John Thomas]

Looking for some help. The engine will not turn-over.
Did a heater core replacement which involved pulling the dash and support skeleton out. To allow sufficient travel the wiring to the fuse box was disconnected. Putt all wires and clips back together. Power to dash instrument and fan.
Any thoughts?

Did you get all the grounds connected back, if you may have missed one it could be your problem.

Bit more info needed. Give us a year and engine at a minimum.

What happens when you turn the key? Do you hear the starter solenoid click?
Are you talking about the engine fan or blower fan?
All the grounds get reconnected. That would be my first guess is that a ground got missed, or some other connection.

What others have said. I would start by runnning a jumper cable from the batt neg to the block. If problem goes away, you have a bad ground(s)
