I am selling my truck on cl, enough heartburn for me...
TACOMA BUYERS: BE WARNED - DO NOT EXPECT TOYOTA RELIABILITY FROM TOYOTA TACOMA TRUCKS - THEY ARE ABSOLUTELY UNRELIABLE, TOYOTA MAKES JUNK IN THE NAME OF TACOMA's (2002)
My previous posts:
Its been just 17 days and my Tacoma has the same problem all over again. ~30F ambient this morning, the motor turned but would not start, had AAA tow it to the same dealer. One thing I noticed is that my gas level is almost the same everytime I have this $700 problem, its halfway between the last quarter and E on the guage? Bad floater? Now What? With a new onboard computer, fuel pump, what's wrong? Anyone with a similar 02XC, 2.7L have similar problems.
TACOMA's ARE ABSOLUTELY UNRELIABLE. After I get this fixed, I'm fearing if this should occur on a busy Interstate someday, if given a choice, NEVER EVER buy a Tacoma outside of factory warranty. I am waiting for the dealer now to call me and give me a new estimate...

Hi Guys, I have a problem with my 02, XC, 42k, pre-runner. On sunday, with ~40F ambient, my truck would not start at all, it would crank well but did not start. I tried everything mentioned in the manual (alleviate flooding etc), but nothing worked. No use using a jump because the battery looked healthy. Eventually I had it towed to a dealer on Monday at 8AM, the guys there spent the whole day trying to diagnose the problem, at 5PM, they called me - it's "partially" the onboard computer and "partially" the fuel pump to blame. Since the onboard computer is still under warranty ( I think 60k) and I have a 6yr/100k extended warranty passed on from the owner, I didnt care to ask what "partially" means...but this was surprising to me because its too early for the pump and computer to die. And I am not questioning the dealers diagnosis because they had quite a number of people look at it. Has anyone experienced a similar problem this early or is that an isolated case. I am troubled with this experience, Toyota is much much better, I am sure.
#1851 of 2067 Piston Slap/ Cold Morning Knocking Sound
Feb 20, 2006 (2:13 pm)
Does anyone have a piston problem with their toyota trucks?
Piston slap is also known as "Cold Morning Knock" or "Cold Knock" and it is a rattling sound during a start up when the weather is cold and the car has been sitting over night.
If you want to learn more about it and hear the sound, goto www.pistonslap.com
I have a '99 tacoma with 67k and it started doing that recently, after five years of no problems in the past. The service dept at a toyota dealer finally heard the noise and diagnosed it as a "piston slap" and said it is normal, nothing to worry about, will not affect the durability of my car. However, it IS a big deal! and I am finding out that I am not the only one with a piston slap problem (although the manager claims I am). So, I am making a list of toyota owners with this problem to present to the Toyota itself and see what they will do about it.
Ford and Chrysler have already replaced thousands of engines b/c they recognize it as a big problem where as GM is refusing to do the same for their customers.
If you're having the same problems and want Toyota to do something about it, email me and be on my list.

Don't sell the truck yet. You are facing the reality that the dealer was unable to find the cause of your problem. Their solution was to take a wild guess in the wind and charge you a bunch of money. I recently had the same type of frustrating problem on my 2000 2.7 pre-runner. No trouble codes showing and the truck would stall in traffic and not restart. After replacing the computer ($350 used on the internet) the problem showed up again. A recommended local mechanic found my problem and charged me $75. (A loose electrical connection in the fuse/relay box under the hood. A fuse had burned out and the previous owner did not have the correct type so he jury rigged a wire in there to complete the connection. Most of the time it worked, but when it didn't the truck wouldn't run at all. You can isolate the problem a little better yourself by removing one of the plug wires at the coil/igniter when the car won't start. Have a helper turn over the engine while you hold the loose wire an inch or so away from its connection. The spark, if you have one should jump the gap an inch or so. If there is no spark you have an electrical problem. If there is a spark you most likely have some type of fuel problem. I cannot stress enough the value of a good reliable independent local mechanic.

That's odd that you say GM is refusing to do anything (not unbelievable, but odd). In 1976, my sister ordered a new Chevy Caprice Classic that had piston slap noticed by the dealer at delivery. They said they would rebore the block and sleeve it, but offered her the option of a new vehicle if she wanted to wait a few wks for delivery. I thought that was very responsible of them. In this case, the slap was caused by one cylinder bore being just a bit out of alignment. The repair was to rebore and sleeve all cylinders in the block.

I know that you're frustrated, but before you sell it off at a loss (or at someone else's expense and frustration), did you check the things I suggested?
1-Did anyone clean the fuel tank?
(As noted in earlier response, it's good practice to keep the fuel tank as full as possible. In cooler weather, condensation accummulates in the fuel tank. The more air in the tank (i.e. lower fuel level) the more moisture that will condense in the tank. )
2-Also, water and trash generally will accummulate in the bottom of the tank (gasoline is less dense). Once the float and pickup get very low, the chance of sucking in water or trash increases. Fill the tank full and he pickup is higher in the tank and gets a light flushing.
3-It is also possible that there is a crack or leak in the pickup. The leak may be submerged when the tank is at higher levels, but when the arm is near the bottom of the travel, the leak may be exposed to the air. This could allow some air to be entrained in the pickup, resulting in low fuel pressure.
If your observation that it only happens in the last 1/8 of a tank is correct, that's a pretty good clue. Does it solve the prblem if you merely fill the tank?
If you add only a gallon, does that immediately solve the prblm?(If so, then maybe the gage is off)
If one gallon doesn't solve it, but a fillup does, maybe you have water/trash in the tank and it merely needs flushing and a new filter.
I agree w earlier posts, if you haven't tried another mechanic or Toy shop, you shouldn't give up yet. After all,what are you going to do? -Sell it at a loss when you disclose it to the purchaser? (I did that with the pathetic Ford Ranger I bought in 1984, after fighting it for years. The guys bought it from me at a price that he could afford to replace the engine -and he finally did.) Or are you going to rip someone by selling them a faulty truck w/o disclosing it (which may be what happened to you)?
#1855 of 2067 Re: 2001 Tacoma, Poor Gas Milage [kcurtis]
Feb 21, 2006 (10:35 am)
Sorry it took so long to reply. I only check this about 1/wk. I had identical mileage to that on my new 4cyl Taco precrunner 2.7L (2000)90K Miles. No tune up or any of that nonsense will improve your mileage. This engine is just a bit too small for this truck, and with any normal highway driving it will get poor mileage. I have several friends with 6cyl and they routinely get better mileage than I do.
Regardless, about 20K ago I purchased new tires and this made a huge huge HUGE! difference. I purchased Michellin tires, same size as the stock Gyears. I noticed right away that my my mileage seemed better, then I started to track it. I have been keeping an Excel sheet for the past year or so and I am now at an average mileage of 22.8 MPG with a standard deviation of 0.5 MPG These tires (about $600 installed) have literally paid for themselves in gas savings. = +5 MPG is about 150 extra miles per tank ca/ 5-6 gallons is about $12.00 per tank I am saving in gas. That was 20K miles ago, which is about $600 in gas savings. I didn't believe this until I started tracking all of my mileage etc. etc.
Also, just to put the issue to rest, because I know it is B.S I used premium gasoline for 4 months straight and my mileage didn't change one iota... statistically speaking. It didn't run better and the only thing I was out was an extra $0.15 a gallon...
Buy new tires. These were Mich 255 75R15 LTX SUV tires with 5x rating for water. They are a driving tire, not an offroad tire, they are quiet, stick like glue and handle about 1000x better than the OEM Goodyears. I was blown away and wouldn't have believed it unless I had kept the data.
#1856 of 2067 Hi amp altenator for Tocoma 3.4 V-6
Feb 22, 2006 (10:23 am)
Where can I purchase a hi amp alternator? I would like about 130amps. I know it will be an after market. I don't want to pay an arm & a leg. One place wanted $800.

Search your local phone book. There are places that can re-wind your stock alternator and beef up the amperage.
In my area Ohio Generator does this stuff.

Hey, I have the same problem with my Tacoma. I have a 2006 double cab sr5. I'm going to the dealership to get it checked out. Did you find out the source of your problem. I noticed that it happens a lot when you go over a speed bump.
