Intermittent Ignition problem

I have a 2008 V-6 Tacoma access cab, about 92,000 miles. When the key is turned to start it, I will hear a single click. Sometimes after 3 or 4 attempts to start it, it starts immediately. this has happened about 3 times this past year. I put a new battery in it, and the same thing happened the very next day. About 2 hours later, it started no problem. Have not had the problem for about 3 months until today. Same routine, clicks only, then a couple hours later, started right off. Could it be an ignition switch problem, or is there a relay in the starter circuit that might be bad? Any ideas??? These intermittent problems are a pain. Thanks!

 

Have you checked all your connections at the battery and starter to make sure they are clean and tight?

Start by cleaning all the connections to the electrical. You might have corrosion at the connections. It doesn't hurt to clean them off.

 

The weak link on these starters is the Solenoid Contacts which are prone to wear and charring. Indications are one single click and then nothing. That click is the starter relay which sends power to the starter solenoid to pull it in. The solenoid pulls in the plunger that connects the copper contacts for the starter motor power and extends the bendix gear to engage the flywheel. The problem is the copper contacts inside the solenoid are burned and need to be replaced.

The issue can be very intermittent or it can be persistent.

You can buy the contacts and plunger new from Nations Starter and Alternator for about 30 - 35 bucks. Much cheaper than hundreds for a rebuilt POS from Autozone or big bucks from the dealer.

Check this video for rebuilding the solenoid on the starter. The biggest issue with the V6 Engine and 4X4 is you have to take the starter out through the drivers wheel well area.

I rebuilt my starter solenoid for 30 bucks and 45 minutes in my driveway.

 

Thanks for the information. The rebuild kit is on order.
