There must be a short in the electrical circuit board the is behind the speedo , probably caused by whatever caused the crack, you will need to remove the speedo unit and check the rear for signs of burning,corrosion , loose electronic parts etc , if all looks ok with the ignition on and engine running remove one bulb at a time and see if ALL lights go out , if so then whatever that particular bulb was for is the circuit on the speedo head at issue,you havent said what vehicle etc if it is pre 2000 this is proberly going to help you if POST 2000 then it may not as around then all manufactures where using LED's instead of bulbs so a new speedo unit would be required or taken to a auto electrician who is experienced in these type of intricate repairs

Speedometer not working

If the speedo and odometer do not work, the problem is usually the speed sensor in the transmission. If the odometer works but not the speedo, the problem is usually inside the speedometer assembly.

Turn key and just a loud click starter not turning but I noticed when key is in start position all power seems to go out dash lights radieo dome everything goes out until key is returned to run pos.

Everything is supposed to go off in the start position. You would have power to the engine computer and other components to start.
If the engine is not locked up, it could be the starter or a bad connection with one of the battery cables.

With key in the off position, hold the reset on the trip portion of speedometer until the light comes on. Allow the vehicle to reset everything, and then test it by turning the key on. Sometimes it takes a few tries to get it right but this should fix your problem.

Car stays on high idle

I have had this happen on saturns before and it has turned out to be a bad intake gasket. The gasket cracks allow extra air to get into the engine causing it to idle high. It also will normally have the check engine light come on indicating a cylinder misfire. 4 thumbs up is appreciated if this helps

While I was driving my 2002 Voyager the fuel,temp and speedometer gauges stopped working, then I went to turn and noticed the turn signals also were not working. Then I went to turn on the hazards and...

It sounds like your ignition key isn't returning all the way back from the start position to the run position because the return spring has gotten weak. The next time it happens try turning the key back to the run position.

Replace the speed sensor on the transmission. This controls the speedometer.
