The breakdown service could not start the car - Please i need some diagnosis advice for my Mazda 323F GXI, 1.5cc, year 2000.

I bought a new battery as my frustration was too much for me and all the embarrassment on my street. The brand new battery still did not start the car and also jump starting does not work anymore, there seems to be something blocking the car from starting.

The breakdown service spent almost two hours trying to start it. He did not have the car diagnostic equipment for Japanese, all the checks was done manually.

Mechanic's diagnoses are below.

None start no switching at injectors no spark at spark plugs and no fuel pump. No live to fuel pump but live at injectors and coils. Please help.

 

There is an inertia switch which will turn off the fuel pump in an accident. Maybe something triggered that switch. Check your owner's manual on where it is.
I hope that's it. Did the mechanic look at all the fuses?

 

Hello Tanprotege,

The mechanic tested all the fuses and they were all okay, he attempted looking for inertia switch all over but he couldn't find it, any idea where this inertia switch is located??

Many Thanks

 

In race cars, they are usually installed ahead of the fuel pump, or very near the fuel tank.
On a 323 I can only guess.

 

Notsure: I may have given incorrect information. The Haynes manual does not refer to a inertia switch. Maybe these cars don't have one. Please check the owner's manual if you have it. I don't have access to my 98 protege and manual right now.
You really need the wiring diagrams for the starting and fuel systems. These will show all the components. With that in hand you can test each part and track down the piece that's bad.
Google for images, I typically find some diagrams that way.

Sorry, that's all I can do at this point.

 

Thanks for all advice

 

The car is now starting and working, crankshaft sensor was replaced, part cost £114, thanks again, all glory to God
