Tacoma issues are going to make me cry

So the 2012 Tacoma owners manual does in fact show keys both for vehicles with and without immobilizer systems! Learn something new everyday.

Anyone know what vehicles don't have immobilizers? Based on engine or something?

 

No, thank goodness.

My '13 base AC just has a plain 'ole key. Exactly what I want.

 

While waiting to determine if there's an immobilizer, issue -
There is an 'amplifier ring' just behind the keyway to pick up/transpond to/from the key chip, and pass the chip information to the computer.
If that amplifier is on the fritz it won't recog. any key.
It's known to go intermittent in at least another post. Unlikely to set any code, just let it crank....

OBTW: X4 on the ether; nix using that old-school carburetor-era fix to avoid f-up of your o2 sensors and catalysts.

 

X2. Less problems when things are simple.

 

If the OP ever comes back...

If you have a V6 engine then you do have an immobilizer and that could be the problem as others have suggested.

If you have the 4 cyl then you do not have an immobilizer and you can ignore everyone saying it is the immobilizer

 

Did you check your battery??

 

X2

 

No.
A bad starter would either turn over slow, or not turn over at all. That's it. a bad starter is not going to cause the fuel pump to not run, or the spark plugs to not fire.

A crank sensor, or something in the connection, could be one of several options. Having a scan tool, or an ultragauge to look at the engine data would be very helpful.

 

Oh. You're right. That must be it.

 

My 09 Regular Cab doesn't have an immobilizer and the keys aren't chipped.

 

V6 thing

 

Stop saying it's the battery.

 

It's the battery.

just kidding its something else

 

Make sure insurance is paid up and strike a match? All kidding aside, good luck op.

 

Did you check for Codes?

 

Bad ECM
Low Tire Pressure
Low Blinker Fluid

 

Piston return springs?

 

Nope. Don't have it and don't want it. Expensive pain in the rear. I get keys cut for a buck fifty anywhere. I don't think any of the 2.7 liter 2TR engine models have the immobilizer.

 

IF you bought the "Courtesy Pkg" (i.e. alarm + other stuff) would it be in there ?? Just a thought but I may be wrong.

 

Inertia switch ? Do our trucks have those?
