Customer Question

I have a 2008 Tundra that intermittently won't fire. I carry a new toyota key just in case it won't fire and today no key would work. Engine just spins over by the starter. About 6 tries and then it fires, or if I let it sit for a bit usually it will fire. So if it is the immobilization system how is that fixed

When it doesn't fire do you see a small padlock symbol like this one on the dash? http://carwarninglight.com/im_p/car_warning_light_w_immobilizer_theft_prevention_red.png

Customer: replied 5 months ago.
Ya right of the clock in the middle of the dash. Flashes before the key is installed in the ignition
Expert:  Your Toyota Guy replied 5 months ago.

But does it flash when the engine is turning over and not starting?

Customer: replied 5 months ago.
No. Doesn't flash light goes out until key is removed
Expert:  Your Toyota Guy replied 5 months ago.

Ok, so the key is not the problem. The flashing means the computer doesn't see a good key and will not turn on the fuel injectors. Does the check engine light illuminate when you turn the ignition to on?

Customer: replied 5 months ago.
The light goes out as soon as the key Is turned in the acc position
Expert:  Your Toyota Guy replied 5 months ago.

So the light is off, you insert the key then turn it to the on position (not start) the Check Engine light should come on for a few seconds then go off.

Customer: replied 5 months ago.
you are correct
Customer: replied 5 months ago.
No check engine lights when running either
Expert:  Your Toyota Guy replied 5 months ago.

Ok, from the information you have given me I would go with the fuel pump. It sounds like it is losing pressure and it possibly has a defective check valve.

Customer: replied 5 months ago.
the check valve is in the pump? Pump in the tank? Is the fuel pump something that a semi mechanically inclined person can do? Seems to never have an issue in the morning just after I drive it a bit and only happens once in a great while but always at the worst time.
Expert:  Your Toyota Guy replied 5 months ago.

It is not hard to change, lift the bed off for the absolute easiest access, 4 bolts then have someone help you lift it. The pump is right in the top of the tank.

Truck only has 56000 miles
Expert:  Your Toyota Guy replied 5 months ago.

Those fuel pumps work really hard all the time. Not uncommon at all for them to go out.

Expert:  Your Toyota Guy replied 5 months ago.

Especially if the truck is driven with 1/4 of a tank of gas or less a lot.

Customer: replied 5 months ago.
Copy. Best is to stay with toyota brand? Which is a dealer purchase. Any other possible things it could be? I was told a crank sensor. What is your thoughts
Customer: replied 5 months ago.
Any ball park idea what a fuel pump should cost? Seems like local business have a huge markup around here.
Expert:  Your Toyota Guy replied 5 months ago.

Crank sensor would have set the check engine light. An old timer's way of double checking would be buy some starting fluid at your nearest auto parts store and next time the truck won't start, spray some starting fluid in to the air cleaner hose and try to start the truck. if it starts then you have a fuel pump problem.

Expert:  Your Toyota Guy replied 5 months ago.

Aftermarket on the fuel pump is fine shouldn't cost more than $125-$150;

Customer: replied 5 months ago.
Sweet! You just answered my next question about the starting fluid. Is there a filter before the pump in the tank?
Expert:  Your Toyota Guy replied 5 months ago.

Yes but I have NEVER seen one of the Toyota filters go bad (mainly because of the filter on the pump itself, nothing ever has a chance to get to the secondary filter.

Copy. When changing the pump is there any other things that I will need? Clamps, hoses ect?
There is also one other issues. When on dry pavement making a fast left turn on the hwy the traction control kicks in making beeping and weird noise on the brake peddle. I tried the same corner with the traction control off and the tow button on and still engaged the traction control. Making a right turn on same corner no problems
Expert:  Your Toyota Guy replied 5 months ago.

Nothing else needed. As for as the traction control problem, you need to see a dealer and have them reset the zero point calibration, takes only a minute and will cost $25-$50 depending on the dealer, long story short your truck thinks you are turning at a severe angle and the truck is on an incline. Just need to reset it so it knows what level ground looks like again, lol.

Expert:  Your Toyota Guy replied 5 months ago.

I have to sign off for now but I think you have the problem kicked now.
