Once every week or two, when I attempt to start my truck, I'll turn the key to the start position, but the engine will not turn over. All the dash lights illuminate, but nothing but silence under the hood. I'll return the key to the off position, then try it again. Nothing, not even the click of the starter solenoid. Then, usually, on the third try, it will fire off strongly as if nothing were amiss.
I suspected the battery (last one failed after about a year), so I took the truck back to Wal-Mart, and they performed a complete system check, the one where they have you turn on your high beams and blower motor. No problems were noted.
I've read the manual and know there are a list of possible causes including the starter relay, starter solenoid, starter motor, lock-out switch, ignition switch, corroded terminals, etc, but you know how hard intermittent problems to troubleshoot. I could go through the troubleshooting procedures and everything could be fine on that particular day.
Yesterday morning, I had to do the start-off-start-off-start thing before it fired up, but this morning, first try.
Any ideas on the most likely culprit?
My Tundra is a 2000 SR5 Access Cab V-8.
