Wait to start light/fuse

[Justin2000]

hello guys, im new to this forum here, and i have a quick question. I bought an all stock never chipped 2000 f-350 XL single cab 4x4 automatic 140,000. Now the guy i bought it from showed me this, occasionally the wait to start light wont come on, reguardless if the truck is warm or cold. when it doesnt come on i have to wiggle a 15amp fuse under the dash and it fixes the problem. The truck starts, runs, and drives great. Its more of an inconvience than anything. Any ideas how to fix it? or if you have heard of such problems? any help is appreciated.

Thanks, Justin

More than likely it's a worn fuse holder. Maybe it had a tap in it at one time, one a loose connection on the back of the fuse block.
