thank you Katman, the problem with the P29 ECU is that it doesn´t prime the fuel pump and also a check engine light ON with no codes, change the main relay, and also all the capacitors.
i been told that i need to change the IC17, and also the Q3 transistor because is leaking but with this Q3 i don´t see the part number, I have been researching and in a forum found tha it´s 2SD1779, and now trying to find the replacement for Q3
Betting it's IC17.
IC17 is key way to several important ECU functions.
I recently replaced caps and then IC17 on a P28 that was acting 'dead'. No FP activation, no injectors firing, nor any regular ecu functionality that the test bench LED's were showing. After IC17 was replaced (last item I replaced after all the caps replaced).... boom back to life.
