i think that then this problem started. i dont know exactly. when i take the plug out then the engine works even worse. it was sale with diesel pump failure. but i think that the diesel pump is fine. anyway it would be good to diagnose the car, but i cant.
ok we mesured in diagnostic connector (i dont remember exactly) one pin was 12v other - the rest of pins were no resistance accsept pin nr 7 there ws resistance with - .hope you understand
ok. but in diagnostic connector there is only one wire for ecu,radio and speedometer. why i need more? yes w tried to search them. one tester wire to pin 7 and we tried all pins in ecu connector put no luck.
witch pin in ecu is diagnostic pin? maybe if i cut of the old wire and replace it with new. on end to the ecu and an other to diagnostic connector. then ill get acsess to ecu.
pin 7 was ok. we removed radio and speedometer. still no response from ECM. somethin is blocking signal. i think i need a wiring chart that i can get singnal straight from ECM.
it didnt find speedo also. i think we dint tried to access radio. abs, airbags and central locking were ok. it means that equipment found them. maybe theres a fault in daignostic connector.
