2004 Mazda 3 BK 1.6 was created by Edward9637
I have a no communication, 5V reference wire is 11 Volts, guages go erratic, Odometer stays on when car is off, fuel pump gets constant power and, it only runs a few seconds after starting and sounds like a bulldozer with the flu.
Someone tried to jump the Intake Shutter Value Solenoid by connecting to the purge solenoid and also, there are 2 wires near the passenger headlight not connected.
When I returned to the Philippines, I found wires broken and hopefully, fixed them properly. I also found 2 old codes about the EGR solenoid valve and a bad O2 sensor.
I only have basic tools here and can not afford to take the car to Mazda to have it checked due to my daughter's transplant surgery.
I don't want to believe the PCM is cooked due to the fuses being popped.
Any direction at all would be a big help.
