Honda Civic - Car won't fire up after engine stall
We have got a Honda Civic 2005 model, the problem is when you stop the car abruptly, the engine stalls and doesn't start. You have to wait sometimes and sometimes need people to push it before it firesup again. We have get the battery check and the sensors, got them replaced too. We also took it to Honda service station and they couldn't figure out the issue. Please advise.
One more thing it was earlier on CNG but the CNG emulator wiring has been disconnected and still the same issue.
First, what do you mean by not starting? Will it crank?
Does the fuel pump prime? Can you hear the main relay click? I can see hearing the fuel pump a problem due to noise however the most cost-effective way is to hear for its distinct humming sound after switching the ignition on. Same applies for the main relay-if it ever stalls in the quiet of your home.
Also, I have seen bad ECU fuses do this occasionally, check into that. If corrosion is present on the terminals clean it with a salt and vinegar solution following by caustic soda solution.
Did you check the sensors for continuity? Don't spend your money on false guidance. Replace what needs replacement and you are affirmed about. It may cost you a penny after all to end the issues with just a little bit of insight.
As for wiring, have it soldered and heat shrinked for the better.
