Sienna With Hard Start In The Morning. by jothan(m): 12:19pm On Jun 14 Dear Auto Gurus, I bought a 2001 Toyota Siena (automatic transmission) few months ago and since then I have discovered the car has a peculiar problem. I observed that whenever the vehicle's engine is cold and you start the car and for whatever reason, you turn off the engine, the car will not be able to start except you leave it for a long while like 30mins before it will be able to start again. Again, if you drive the car to the office which takes about 20mins, (by this time the engine is hot) you can turn off/start the car as many times as you wish and the car will respond. i have changed cold start, changed the fuel pump and stil to no avail. Pls, what do i do. See what I meant. Ikenna. |

I have this challenge of changing my fuel pump. When i park it wont start my mechanic change the fuel pump twice and told me that the fuel pump is working. Base on other experience on the cold start valve i will tell an auto electrician to check it. Right now my car is parked on the road. |

ebhohon:u need to change ur mechanic and rewire ,all of them are working blindly.u will need to run diagnosis on your car to resolve this issue ,this will pin point the root of the issue instead of your mechanic approach of throwing part at issue. call autologic @ 08061166316 to run diagnosis on your car. |

I have tried to use diagnosis but i was told that diagnosis cannot work if it doesn't start. Now they said it is crankshaft position sensor |
Re: My Car Won't Start When The Engine Is Cold, Why? by honmusa(m): 11:22am On Jan 04, 2016 |
car diagnosis is limited by the skill level and the equipment of the person doing the troubleshooting for u . |
Re: My Car Won't Start When The Engine Is Cold, Why? by ebhohon: 8:23pm On Jan 04, 2016 |
Someone brought diagnosis and said it is brain box which i disagree with him because my friend brought his car, the car brain box was used in my car it didnt work my brain box was used in his car it worked which means my car brain box is ok. What i need is a knowledgable technician. |
Re: My Car Won't Start When The Engine Is Cold, Why? by honmusa(m): 7:33am On Jan 05, 2016 |
Have u called autologic ? Diagnosis doesn't necessary means a particular equipment ,it involves all the the whole array of equipment and mental skill to troubleshoot and resolve a particular issue . |

Hello bro, the problem with your early morning hard start is COLD START SENSOR professionallycalled ECT( Engine Coolant Temperature Sensor). Pls do not heed to the advice of removing your thermostat. Mechanics do so cos they don't understand the principles of car thermostat. It plugs into the coolant base and senses when the engine is hot from the coolant and switches on the thermostat which controls the fan and vice versa when cold is switches the fan off. So when the sensor goes the thermostat won't be able to start the fan. This can lead to over heating. Thus they will tell you to remove your thermostat without understanding. The solution is just to replace your cold start sensor or ECT sensor. You can Google ECT sensor and its functions bro. Don't destroy your innocent car. Infact the presence of thermostat saves fuel as it help your engine relax at intervals than remaining on a steady high steaming with stead fan cooling. The fan also places demand on your engine. Also it brings down the steaming sound of your engine from high to low. GOODLUCK. |
