Just purchased a 1995 H1 Hummer. When starting, you turn the key, and the Wait light illuminates as well as the filter drain light. Once the wait light goes off, you can then start it.

The last several times, I have went to start it, the wait light does not appear, and the hummer will crank but not start. After several cycles of the key, the wait light comes on.

Now the Wait light will not come on. Any ideas?
