Good evening boss, I was working on a car today Corolla 2009 with a 2zr engine. Before accident, the car was starting fine without problems. During the course of repairs engine had to be removed. After the repairs engine was replaced everything was put back in place except for the airbags they were yet to be replaced because of funds. Here is the problem, I have spark, fuel, compression, at times it will do as if it wanna start but it won't start after a very long crank. No fault codes present In the Powertrain ECU. I'm just stuck as I don't know what to do, though the engine sat outside the car for about a week. |

Billiebaba:Confirm timing is correct... Presence of air, fuel and spark at wrong time, d engine will never run. Let us start with confirming ignition timing is correct. If timing is correct , then lets check the sensors responsible for letting the computer know when to fire the ignition and injectors... These are the Cam and Crank sensors... Confirm they work as they should 1 Like |

AutoMoTech:Is there a way of checking it without a scope and without removing the valve cover |
Re: REMOTE FAULT ASSESSMENT AND DIAGNOSIS GUIDE By AutoMoTech by AutoMoTech(m): 8:53pm On Mar 16, 2020 |
Billiebaba:To check without removing valve cover you need a scope sir. Best way to confirm timing is via a scope. |

Please I don't know what happened to my baby boy Honda Accord, anytime I started the engine it working fine but after the engine is hot it will not accelerate more than 3 instead of 5 |
Re: REMOTE FAULT ASSESSMENT AND DIAGNOSIS GUIDE By AutoMoTech by AutoMoTech(m): 11:10am On Mar 19, 2020 |
Stewart883:have you tried to check if one or some of the AC vents are open thereby allowing hot hair blow into the cabin? 1. check the vents? 2. check your ac settings? make sure its set to cold and not hot. 3. finally change the other vent settings to recycle and not to allow outside air in. |
Re: REMOTE FAULT ASSESSMENT AND DIAGNOSIS GUIDE By AutoMoTech by AutoMoTech(m): 11:12am On Mar 19, 2020 |
danitto: so many things can cause low power. 1. cloggged exhaust 2. weak fuel pump 3. electrical faults etc... among other things. kindly find a competent technician who can help diagnose the cause of the low power |
Re: REMOTE FAULT ASSESSMENT AND DIAGNOSIS GUIDE By AutoMoTech by Stewart883(m): 5:51pm On Mar 19, 2020 |
AutoMoTech: Thank you for your response. The vents are closed and the ac setting is on cold. Don't know why it's always hot inside |
Re: REMOTE FAULT ASSESSMENT AND DIAGNOSIS GUIDE By AutoMoTech by AutoMoTech(m): 6:01am On Mar 20, 2020 |
Stewart883:Check the heat shields. Its possible there is transfer of heat from the engine compartment into the passenger cabin. |

Greetings My car Toyota Camry 08 grunmble when accelerating from gear 1 to 2, Buts fade away as the gear increases. Sometimes, while driving and about to make a stop and move again, it will delay about 2 to 3 secs before picking. Pls I will appreciate whosever has experience it and solutions. Thanks |
Re: REMOTE FAULT ASSESSMENT AND DIAGNOSIS GUIDE By AutoMoTech by AutoMoTech(m): 9:04am On Mar 20, 2020 |
vinzita1: For now it sounds like a loss of power on intial throttling/accereleration. Check your fuel and ignition system Clean injectors if clogged Clean plugs if dirty |
Re: REMOTE FAULT ASSESSMENT AND DIAGNOSIS GUIDE By AutoMoTech by vinzita1(m): 10:29am On Mar 20, 2020 |
Yes The sound is like vibration, through the cabin, Especially when I want to accelerate to move faster,as I move on the sound fade away. But if I am to move in slow pace , the sound won't be heard. As to the delay It happens whenever am moving and press brake to stop slowly, then accelerate to pickup, it delays for about 2 to 3 secs before connecting the right gear to move on. |
Re: REMOTE FAULT ASSESSMENT AND DIAGNOSIS GUIDE By AutoMoTech by AutoMoTech(m): 6:50pm On Mar 20, 2020 |
vinzita1:Feels like low power due to misfire on light throttle. Kindly find a professional auto tech to help with the diagnosis of this issue. Check your fuel supply Ignition system Air Vacuum leak among other things |

Hello, NLers. I want to know if Honda City is a good buy. The car is a Nigerian used 2007 model with auto transmission. Selling price at 400k. It has a bad gear, AC. Kindly school me if it's a good buy looking at cost of maintenance, fuel consumption. Thank you. |
Re: REMOTE FAULT ASSESSMENT AND DIAGNOSIS GUIDE By AutoMoTech by Waxxxy: 9:17pm On Apr 03, 2020 |
AutoMoTech: Thank you I bought cabu cleaner @ 500 and spray it on the throttle body then I use my finger to clean the inside. It was actually black and after cleaning I relean the car with a method I saw online and the car stopped vibrating in idle and my idle guage is 800 |
Re: REMOTE FAULT ASSESSMENT AND DIAGNOSIS GUIDE By AutoMoTech by Waxxxy: 9:19pm On Apr 03, 2020 |
AutoMoTech: Thank you have done that and the car has stopped vibrating |

Waxxxy:Now thats Beautiful. The fact you did it yourself even gives me more joy |
Re: REMOTE FAULT ASSESSMENT AND DIAGNOSIS GUIDE By AutoMoTech by Allem(m): 9:08am On Apr 04, 2020 |
What method did you see online pls share with us or the link Waxxxy: |
Re: REMOTE FAULT ASSESSMENT AND DIAGNOSIS GUIDE By AutoMoTech by Waxxxy: 10:00am On Apr 04, 2020 |
After cleaning the throttle body and coupling,I started the car and the idle was 1500. The method I used Note: make sure the engine is warm before performing the relean procedure *insert the key into the ignition & turn the key to ON position then take it back to OFF position *turn the key back to ON position & turn it back to OFF position again. *Start the car and make sure all gadget I.e radio, A.C. and other things are switched OFF *Press your brake and put your handbrake ON *Shift your gear to drive and let the car stay for about 3-5mins You will also be seeing the rpm going down gradually till it get to 1000 or below. *OFF the car after the rpm stops reducing. *Start the car and you are ready to go What method did you see online pls share with us or the link[/quote] |

I just did a scan on my 2005 Toyota corolla because I want to know the reason why the check light ON starting from the day I went to panel beater for body work in Lagos The scanning result shows threshold efficiency low. I was told I have bad catalyst but I didn't believe because the car is less than 3 months old. To clear my doubt I went to a panel beater and I discovered that the catalyst is missing in action. Am surprise, I started thinking if it was removed before shipping the car or the Lagos panel beater play a fast one on me. |

Re: REMOTE FAULT ASSESSMENT AND DIAGNOSIS GUIDE By AutoMoTech by AutoMoTech(m): 2:04pm On Apr 04, 2020 |
Waxxxy:Can you see any points where it was cut and then welded back again? PLS do not agree if your panelbeater says you can put wires inside. It's better there is nothing inside. Also try if you can get O2 spacers. Rather than spend so much buying the exhaust cat, just attach the spacer and enjoy your motor |
