If it happens more than one in ten starts, I'd also suspect the switches.

There actually was a thread dedicated to a longer pause after pulling the fuse, c'mon SouthArk!!! You're slackin'!!!

There have been some reports of it making the pause longer, but nothing I would consider "scientific." I'm all but convinced that the brake/clutch switches are the culprit for long pauses. Edit: and possibly the reason for all pauses.

My guess as to what is happening is that there is a (filtering) capacitor on the ECM/BCM inputs and when the brake/clutch switches get dirty the extra resistance makes it take longer to charge the cap. If anybody has another theory, chime in.

Hey SouthArk, you don't reckon that the switch contacts are self cleaning? I mean those robust automotive type contacts usually self clean. I would love to see one of those "defectives" disassembled.

Someone did a DIY on cleaning the, IIRC, clutch switch. I vaguely remember there being some pics but my memory ain't what it used to be.

Edit: I did a site search for "clutch switch" and didn't see what I was looking for. Also scanned through the list of threads in the DIY section with no luck. Maybe I dreamed it. Or it is just a few pics in a post and not a full-fledged DIY. Or maybe my mad search skillz are fading.
