This evening my wife went to leave for work. All power seems fine. Tried to jump...no change. Looked at all the related fuses and all are fine. I do not just want to start "throwing parts" at this issue. I feel I can hear a relay clicking under the hood. Any assistance would be appreciated. Any ideas?

 

Jump the starter relay pin 30 and 87 see if the starter will turn over

 

Well after sitting overnight, it started. I am almost disappointed as now I wonder when my Wife or I will get stranded somewhere.

 

Take a close look at the connectors crimped to the battery cables. They've been known to loosen up. Have the battery load tested. It's not unusual for a battery to recover a charge after sitting overnight. If it's original to the van replace it. The average lifespan of a battery is 4-6 years.
