A summary of the circumstances and the verifications already performed my car (MG ZT 190 2.5l V6 ESS (2001)):
Down for 2 months.
Circumstances of failure:
Along the way, loss of power, the motor signal is displayed on the dashboard, followed by a gradual deceleration to a stop the engine. Can not restart.
Here are the previous investigations:
- I first thought of fuel starvation -> by filling 20 liters remained in the tank
- The candles were black and wet -> certainly drowned due to different misfire. I cleaned.
- The relay and fuses associated with the fuel pump -> Ok
- I listened to the pump through the tank -> Ok
- The pump seems to work correctly -> Key in position 1, you can hear turn
- Checking for gas to the injectors -> By disconnecting the supply line, key in position 1, I can gather from 20 to 25 ounces of gasoline
- Check the fuel filter without removing the filter but an attempt to pose an orange collar attaches the filter to set a default pressure -> Failed filter because my model is not compatible with the default . The orange clip is for sale ...
- Checking the crankshaft sensor -> I replace against a new but without effect.
- Verification of probes using a multimeter -> after cleaning and attempt to repair the lambda sensor with a torch, it gives "10 ohms" each. In truth, I do not even use a multimeter ... I have finally replaced by new probes
- Check sensor idle -> complete cleaning and change of the membrane (pending receipt of a new sensor)
- Check intake manifold -> Do not seem dirty, just a little too fat for my taste in the engine cylinders butterflies
- Check the air pressure sensor and temperature -> Thorough cleaning (eventually, I gave a new sensor)
.... etc.
Good short, I managed to restart the engine using the accelerator at the same time. But the problem is that I do not idle the engine. I have to keep the foot on the pedal and keep playing with the accelerator. It releases a lot of smoke at the back and at one point even accelerating the engine floods. And impossible to restart the engine whines again.
