I change the alternator on my 2001 Mazda Protege LX 2.0 and when I Start the car the wiper and light was going very fast. So fast than one of my wiper arm broke. After that, the car stop and doesnt whant to start. I have a good crank but I have no spark at all and no fuel to the injector. In the dash the heat gauge go at the top and I dont see any engine light came on before I crank the car.

I already test:
- Fuel pump
- All relay

I change a lot of part:
- Fuel pump relay
- Crank sensor
- Ignition coil
- Injector
- All fuse
- Alternator is now a new one
- Computer
-.

Now I will look all the wire under the hood.

Anybody can give me a hint what I have to do now?

Thanks,
Steve
