Here is what happens
1st crank - click no start
2nd crank - Click no start
3rd crank - Click half start
4th crank - Click and starts like it should.
This is repeated everytime i start the car, but other than that it runs just fine. Problem has been like this about two weeks or so. Since it was the holidays I just drove my jeep cherokee. But i need to get this fixed before i get back to the normal routine... I have a few ideas what it might be, but no definite.
Help please.
You could go to an auto parts store. The ones in my area (most commonly Advance Auto) do free checking of the charging system (alternator and battery).
If you were trying to restart it when hot, you could have too much metal friction.
Does the starter crank the engine, indicating that the battery has voltage?
Have you had the timing belt replaced in the last 90K miles? Could be the timing belt broke...so check to see if your camshaft is turning.
Assuming that is okay, pull a plug and check for a spark.
The answers in the black box.
Check the duct going into the intake and big rubber hoses attached to the intake manifold and this duct. It starts at the air filter. At three thousnd it might not pick up the air leak since more air is running through the engine at that speed.
I d do your own compression check on the front bank and the one spark plug on the rear bank of cylinders. To get started, you need a spark plug socket and ratchet and extension, plus compression gage at Sears $30.00 dollars. Check My Carspace.
I'd remove it and look under it for a crack along a seam on one of the ribs. A squeeze test of this duct while running, will cause it to stall out.
Dont buy a Mass Air Sensor till your sure it is bad. I bet if you disconnect the Mass Air Flow sensor it will still run. Some cars computers go into default and will still run on the default settings if it senses a malfunction in the Mass Air Flow Sensor.
I just returned from a road trip to New York State. I traveled at 70mph on the NYSTW, and the vehicle got 31mpg! ---- This was achieved on 87 off-brand fuel. ---This is OUTSTANDING for a V6 engine.
On entering the highway from a rest stop, I accelerated "hard" to see how this vehicle would perform. Within seconds it reached 80mph! ----- The shifts were smooth and positive. (The vehicle peformed like a "ROCKET"!) This vehicle could easily cruise at 100mph! (I would love to try this for about 1/2 hour somewhere if "RADAR" was not an issue !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!)--------- It is truly a road car! --- (Life was more fun years ago without road radar.)

Burned/leaking intake valves.
Combusted gasses only leak back into the intake manifold and ignite the gas there (stumble..) with HIGH cylinder charge volume.
Anybody heard of this? Can't find any info on this.... Help.
Did he tell you the error codes that the computer had in it?
You indicate that he is going to replace the air flow sensor AND the manifold....which doesn't make sense for a first time diagnostic problem. I can see replacing a sensor, I can't see replacing a manifold unless there was reason to believe it was cracked or a gasket bad found through other testing.
Get the error codes from him, or if the light is still on go to an autoparts store where they can pull the error codes for you.
Is he talking about the Mass Air Flow sensor, an Oxygen Sensor, or something else?
Thank you!!!!!
I tried sending it to clindstrom@carspace.com, let's see if that works
You need to go to your carspace area, your toolbox, then mailbox section
He stated that these codes (P2195, P0171, P0174) had to do with the oxygen sensor's measuring "to lean", therefore sending data that more fuel is needed and the engine is burning more fuel and emitting more emissions into the environment than it should. He stated "Toyota's fix for this includes changing the O2 sensors and also changing the manifold to a newer style manifold which positions the sensors in a better position" I told him it is a very costly repair for me and he suggested an option of just replacing the O2 sensors with the style that is on there now for a cheaper option.
He said another set of codes also appeared (P0441 & P 0446) that deals with some type of air leak in the fuel system, but does not know if that has to do with the above mentioned problem that is all related.
Any thoughts would be appreciated. How difficult is it to change the O2 sensors on my own?
O2 sensors do go bad, and are reasonably easy to replace. Personally, I would think long and hard about replacing the exhaust manifold.....they would normally last forever on engines, there is nothing to wear. I think I'd be calling the service manager and ask them to escalate to Toyota on your behalf. If there really is a new design manifold, and they are stating the old design is designed defectively, then I'd ask for Toyota to eat the cost of the replacement. I doubt that they'd do that, but I'd be asking.
Was the old fuel pump put back in because the car failed in the same way with the new one..??
Intermittently sticking fuel pressure relief valve would be my next guess/trial.
Try going to a different gas station to use a different pump.
To completely fill the tank, it might take over a half hour or more now!!
You should take the car to a reputable mechanic; you certainly don't want to risk spilling gas on yourself!
thank you
