Question about 1993 Buick Roadmaster
Have it checked for trans codes. there is a speedometer buffer in the instrument panel that could be a problem or the instrument cluster has a problem.

Erratic Speedometer action could be an internal transmission problem. Check the Instrument cluster, vehicle speed buffer and recheck the speed sensor, look at the drive gear inside.

A shotgun approach to repairs can really rack up the bills.
If your symptoms are loss of water and you have replaced the thermostat, you more than likely have an issue with steam. And that steam more than often comes from a bad head gasket. Most head gasket gasket failures seem to be confined to the water side initially, but let it go on bigger damage will occur.
You can buy a litmus test strip to dunk in the coolant. It will indicate if there are exhaust residuals in the water and thus a gasket failure.
However it may just be something simple, given that you have just about replaced everything:
have you given the radiator a good hosing inside and out?
is the radiator fan running when it should be?

Im assuming this is the Series I 3800? If so, if you can email me I can send you some directions on the process. Its for a Series II 3800 but it should be similar. If you cant email me, post up and I'll see what I can do.

Short circuit probably not the problem. The pass key system is not being disabled making the car inoperable, thats why it will not crank. Either you are using a key that does not have the correct resistance(black chip in key) or if it is the same key you always used then the pass key sensor went bad. I believe it is in the steering column and a qualified mechanic could help you there.
