Default Low Power Mode, Warning Lights, Help.

Hey guys just have a question for anyone who's got the answer! So about 6 months ago I was involved in a accident I tweaked the driver frame, and did some body damage. The body shop took it all apart and quoted me 20k I laughed, so took it home fixed the frame myself, put the front clip back together and car back together. Now I turn the vehicle on and it runs, no power windows work other then the driver door, no stereo working only clock, most of the gauges are lite up Vcr I think is flashing, I can get a picture posted when I get to the car again... And when you apply pressure to gas pedal nothing happens until all the way to floor and it revs to like 2500 rpm and stays there. Just curious if the computer just needs reprogramming (reflash) because it was unplugged for 6 months or if I have a wiring problem or something further to deal with? It is the same computer that was unplugged that was put back in.

I doubt its the ecu. I'm afraid in the incident that wiring got crushed or connectors are left undone causing plenty of your issues.

Lets start with what codes the car is throwing; probably quite a few!

During the repair, did you go as fas as removing the motor/trans? What less might have you removed?

I drove the car home after the accident and it ran and drove fine, no wiring was crushed not enough damage. Everything from the front clip mounts forward was replaced (rad, fan, rad support, headlights, bumper). The car just hasn't ran since the computer was unplugged and battery disconnected which was for a time of 5 months. I'm assuming the internal battery died in the computer causing these problems??

I don't have a code reader for codes.
