i have never worked on a toyota until now. my 92 camry started running hot so i replced the thermostat that dint fix it so then i replace my water put. i dont know if that fixed because i have no put everything back together and it wont run! it kinda sounds like the timing is off but dont think it is because the car was not tunred on while the belt was off. maybe its not firing im not reall sure. if any one has gone through this i would really love it if you let me know what the heck is going on.
