Hello, my name is Thierry I have a 1999 Defender 90 TD5, we've owned it for 7 years now and in the last two years its been acting out a lot.
We've added quite a few mods on it 6 years ago, we've added heating seats, new fog lights, kbx lights, a new audio system with a Kenwood (DNX8920) sat-nav system and a subwoofer. We've changed the ecu twice because it stopped working (my mechanic told us so), we've bought both of them from MASTAZ. Last summer we had problem starting it, but with a little bit of gas, it starts. This winter, the truck turned off completely while driving, it shut down on the middle of the road. (This winter it was always plugged to the wall, so the battery could charge itself and the truck wouldn’t start without being plugged or jumped). And we also changed the battery. We brought it in at the beginning of spring and we changed the alternator, it worked for a week, the truck started with no problem, everything worked. Then, the next Monday when I tried to start the truck, NOTHING, the lights on the dash were on, the sat nav turned on, the lights too, but when I put the key in the ignition, it wouldn’t crank (of course, I waited for the spring light to turn off before trying to start it). The same day, in the afternoon my dad came to start it, it cranked and he gives some gas and it started. I went for a ride, came back, turn it off and tried to turn it back on, wouldn’t crank but same as in the morning, the lights were on everything was on in the car. We are fed up, we are not able to fix this our mechanic doesn’t understand too. The gas tank is full. Thank you |

Hello, thank you for the reply, I will ask my mechanic to look for the wiring, the engine earth and ECU seat box earth. I don't think its the starter because sometimes it crank, but if its not the wiring or the earth, I'll try a new starter. And I'll send a message to mastaz.
Thanks |

Why you try to crank but it doesn’t start does the starter click?
I had this recently, was the starter motor solenoid failing, sometimes it would start, sometimes it wouldn’t but was certainly getting worse. If it doesn’t start try rocking the key, turn it back far enough that you can turn to the crank position again but not so far back that the you have to key off completely to get to the crank position again. |

If the starter doesn't do anything it could also have to do with the AS10 or the connection between the ECU and AS10. Roel

Does the starter make a clicking noise when you try to start? Or is it silent? |

A bad starter can also create a problem with the crank sensor pulse, as well as not always turning the engine over.

Yes it can, l had the same with ours, would turn over but poor starting, tried all sorts but a new starter cured it, even though the old one seemed to turn the engine over with no issues.
