i have a mazda 626 2.0 ditd 1998. i repair the denso v5 pump. Car don`t start. When i put off ETC sensor the car got sparks. When i removed ETC sensor, car package recognizes as cold and gives more pressure pump. Than I put back the sensor. The car don’t have minimum. I restored minimum to the gas pedal. It looks good. Car barely move. Start with difficulty attracting. Then, after 2-5 minutes when it is walking, turn off. The check lamp turn on. It seems as if the pump pressure falls, or is disconnected. I repeat the same procedure. The same problems when is cold and when i hot. After that I change the ETC sensor. Still the same situation.
What should I do?
I would change map sensor. My 95 Millinea had same problem. 2.5L Had replaced ECM, IAT SENSOR,MASS AIR FLOW SENSOR. Start. Run. Die. No start. Unplug IAT WOULD START. Finally replaced MASS AIR FLOW. Runs great now.
