We bought our van last November from a dealer. Warranty is over :( Now we've got intermittent startup problems. The main noise is the sound when the engine is trying to turn over but immediately failing. There is no starter "clicking" sound.
When I say intermittent I really mean very rare, like 1 in 30 (or more). It appears to be at random and the weather/temperature doesn't appear to be affecting it.
I tested the battery with my multimeter and it registered at 18 volts. That doesn't seem right.
I also called the local starter/alternator guy and he said he doesn't even have a part number for the starter for my vehicle. He reasoned that since he doesn't have that number he's fairly certain that it's not a part that fails that often or this early in the vehicle's life. He thought maybe it was a bad connection or the battery.
The 18 volt battery is concerning me, but I don't know enough to say for sure.
Please help me diagnose this issue.
