02 Mazda 626 problems was created by Ktipton388
I have a 2002 Mazda 626, 2.0l engine, All new sensors. New fuel pump, filter and injectors. New computer. All new sensors. New coil pack. Car cranks but wont start. Good fuel pressure. Good spark. Good compression. Fuel is getting to the fuel rail but that's it. The injectors are not spraying the fuel like they should. Noid light shows all injectors are working. I can't figure out the problem. It does not have the anti theft system . I've literally tried everything and have worked on this car for 3 years.

Does it run if you spray an alternative fuel in the intake?

Also, how are you sure it doesn't have an immobilizer system?
There are a few diagrams available for the immobilizer on this car...

Sensors are new and so is regulator, entire fuel system was replaced only thing that wasn’t is the fuel rail. Could the new ECM be causing this, it was suppose to be pre programmed but I guess there’s a chance it wasn’t right
