ok so my st205 water pump is hooked up just as it is on the edw except since i didnt have a relay for it so i just ran the wires around the would be relay.
im drawing my power from the cds fuse just like it shows on the ewd and the ground is also ran just like it is on the ewd. the other three wires from the pump hook up to the corisponing wires on the ea1 connector which feed back into the ecu just like it is on the ewd the level sensor has been tested and found that it does close and complete the cuircut i checked continuity between the ecu and sensor plug and fount that im not getting a signal from the ecu to the sensor...... ........ anyone know what kinda signal is sent out from the ecu to the sensor which goes from the sensor (if closed) and to the ground. |

Not sure if you've already figured this out or not...
QUOTE ok so my st205 water pump is hooked up just as it is on the edw except since i didnt have a relay for it so i just ran the wires around the would be relay. What ECU are you using? If your using the 205 ECU, you MUST have the pump relay installed otherwise you can damage the ECU. QUOTE checked continuity between the ecu and sensor plug and fount that im not getting a signal from the ecu to the sensor...... Sounds like a wiring issue. If you dont have continuity between the LEV wire at the ECU and ground, then somethings not connecting. QUOTE anyone know what kinda signal is sent out from the ecu to the sensor which goes from the sensor (if closed) and to the ground. Think of the coolant level sensor as an on-off switch. There is no signal from the ECU, its just checking for a ground to complete the circuit (like the switch is in the on position). If the coolant level drops, the switch turns off and the circuit breaks. You can just jumper the ECU to ground and bypass the sensor altogther as a temp fix. -------------------- Scott
