My wife has a '00 Sequoia and she has been complaining that sometimes it won't start. So today I drove it and I see what she means. It just turns over but won't fire. I hit the gas at one point and the engine kind of made a woof sound. Then I tried to start it again and the same thing, only this time hitting the gas did not start the car. I did not try it again, anyone have any advice as to what it may be. It has 4.7L V-8 with electronic fuel injection.

Thanks

 

Hey were you ever able to solve your starting issues? My wife's '03 Sequoia is having the exact same symptoms. Acts like the timing is way off.

 

I don't know the answer, but it sounds like something to do with the ECU. If so, it and all emissions components are covered under a separate warranty for California owners far more generous than other states. See your warranty guide supplement pamphlet, it could be a free repair.

Ask your dealer to do a code scan to diagnose further. Good luck and let us know.

 

Well after screwing around with my wife's Sequoia for a couple of weeks, I managed to contact NorCalJack and he said that the problem turned out to be his key transponder. He was able to get new keys reprogrammed for a $100 or so. I was not so lucky. A jumper test on the OBD-II connecter confirmed that the Anti-theft computer was Tango-Uniform. At that point I just called a tow truck and the dealer fixed me up for a mere $965. Runs like a champ now but I'm somewhat pissed at Toyota that my "Extracare" warranty was good for 6 yrs/100K and it crapped out at 7yrs/97K. So if your 'yota cranks but won't start, you might save some time and check your Anti-Theft computer first.
