I recently got finished putting my rebuilt engine back in the car. I filled it with fluids and went to go start it, and I didnt do anything. It wont show mileage, crank, fuel pump doesnt prime, and it wont talk to the computer. My fingers are pointing at the PCM but i dont know how it could have gone bad just sitting for 2 months. Me and the guys at my shop have been looking at it for a while and we cant figure it out. Any ideas are welcome.

*EDIT* by computer i mean the scanner is unable to read CEL codes or make any kinda of connection to it. Everything powers up inside, radio, gauges, gauge cluster, locks windows etc. I hear the ignition relay click but no starter relay clicking. Also when I referred to the dash not showing mileage this is what my mileage rectangle screen looks like:

- - - - -
--------

[----------] readout on the odo means your ECU is not communicating. Start by diagnosing that- like is the fuse good? Is there power to the ECU?

Fixed it. There was a ground I didn't hook up that the battery tray was hiding. It all fixed now and i started it for the first time today and it runs great
