Hi.
I have EDC16C39 0281012193 ECU not driving 1 and 4 injectors.
The engine is running but only 2 and 3 cylinders are working.
EDC Lamp is ON.
I have checked all transistors, diodes, fuses and they are all good.
Replaced Mosfet driver IR20153S that was driving a transistor which powered 1 and 4 injector +.
Replaced Bosch 30520 (IC driving injector mosfets).
Finally i thought that it could be a bad joints under MPC562...
I have reballed MPC and soldered it back - still not driving 1 and 4 injector
Any advice?... what can it be?
