Strange glow plug problem ???
Hi All, So I have a JTD 1.9 8V engine. I have had a long problem with getting the glow plugs to work. I have 4 new bosch glow plugs (all under 2 ohms) a new relay, I have cleaned the EGR, and also replaced temperature sensor.
So the problem. If I disconnect the temperature sensor, the glow plugs heat for 6 to 8 seconds, and the car starts fine, but the thermo fans run continuously.
If I connect the temperature sensor, the gauge works fine, but the glow plugs only run for less than 1 second, and it's almost impossible to start. If the car hasn't been started that day they heat for about 1 seond, otherwise they seem to turn off almost straight away.
I have checked all the wires as best I can, and the relays etc. I can only assume the problem if either a connection from one of the ECU wires, or the ECU is playing up.
I was hoping to use a manual switch in the car to run the glow plugs, but I am not sure which wires I should witch.
any ideas ?
