Hi, I have problem with Mazda 323F Year 2000 2.0TD, car won't START. I think the problem is in pump ECU DENSO RF2A18701A. Immo working OK.
Pump ECU have 5 pins:
5.....signal from pump ECU to injector (don't have signal when cranking)---problem pin
4.....GND from pump ECU to injector
3....Signal from ECU to pump ECU (have signal when cranking)
2....+12V
1.....(I think this is the signal from ECU pump to ECU) this pin is the problem, I do not have signal on this...only when I put manal impulses on pin 5 I have signal on this pin, and car is starting as long I put impulses manualy...so I asume that pump ECU is not puting Hi (+12V) pin 5 and that is why I do not have signal on pin1.
Any information will be appreciated.
Thanks!
