Gears & Axles - Speedo Stuck at 200 MPH

Wasn't sure where to post this but I'll try here and computers. I took my Moser rearend back out to adj the backlash and paint it. While it was out I turned the key on, to roll the window down. I noticed the speedo shoot up to 200 MPH stay there. I figured it was because the I had the abs sensors unplugged. Well I put the rear end back in and hooked everything back up and when I turned the key on it stayed at 200. I started it up and let it run for a few but still there at 200. I even tried turning the wheel a few times. the drive shaft is still out because I'm waiting on a DL loop and torque arm, but this is bugging the hell out of me. Why wont it go back to 0.

Oh yea its a granatelli 200 MPH Speedo. I gues would be the same as a normal stuck at 160

Please Help

Have you tried resetting the PCM?

1. Take out the PCM IGN and PCM BAT fuses from the engine compartment
2. Wait 5 minutes.
3. Put fuses back and start the car.
4. You may need to rev it up a bit to keep the car from dieing. After a little while it will stabilize the idle.

Havent tried that yet but I will today. Thanks

Reset PCM and checked all connection Still stuck at 200.

Perhaps try taking the cover off the gauge (may require removing the gauge) and carefully push the nedle away from 200. It might have spiked and become stuck.
