Ignition Problem

[gimmeda8]

Hi, I have an 87 5000s with the 2.3L engine. For the past couple of months my igniton has had a delay between the time I turn the key and the time it engages.

The time has varied: 1-3 seconds. Now, the ignition will not engage.

So, considering the delay, what would be your first idea as to the problem?

Thanks,

James
