I drove my van yesterday it started and ran just fine then later in the day I tried to leave and it wouldn't start. There is power to the dash and radio but there is no power to the fuel pump nor the starter. I checked fuses and relays they are all fine. What other causes could it be?
I'd check voltage at the starter, key in the crank position. Any testing at the starter, make sure the tranny is in park or neutral and the parking brake is set. If you suspect the starter, you can take it off and have it tested.
