问：点火问题

我1995年的GMC SL 3500在开车时死亡。它没有开始。我试图打开，什么也没有。没有坏启动器或任何东西的迹象。立体声和灯光正常。但是，根本没有仪表板灯。我怀疑这是燃烧的保险丝，我对它们进行了检查。他们都很好。我检查了蝙蝠连接的连接，它们也很好。我拖到我的房子里，按照建议，我更改了点火模块。 The new ignition module did not fix the problem. I tested the starter and the starter motor was no working properly. So I replaced the starter and it did not solve my problem. Finally, after couple of days of frustration, I decided to hotwire my GMC. It started right away!!! I drove it and tested. The truck was working and running fine but I noticed that my tranny was not shifting to 4th and 5th gea and together the rpm gauge and speedometer were not working. I went back home and I replaced the ignition switch. I tested the truck and back to problem A! :( :(
