Doesn't matter. Leave it unplugged and the Lambda will switch to safe-mode and still run fine.

Your sure kenodog? I would rather leave it and not worry about that part

For the life of me I can't get this car started
Change
Fuel pump
Fuel relay
Fuel filter
Cis with a working one
Air filter
Plugs
Cap rotor
Fresh battery
Drained the tank fresh fuel

I have to test my relay for power tomorrow and the pump even when I jumped the relay I could not hear the pump on.

So changed some grounds
The car seems to crank stronger

Still not start
There was mud and water at the rear ground in the trunk

So I tried to test the relay point #30 and #87 and nothing zero no power
So now what should I do
I could wire it hot or switch with the audio deck or something

Can someone give me a idea thanks

The switch on the radiator is usually open. When it hits its setpoint, it closes and provides a ground to the fans.

So Paul that does not help me what to check or do?

Paul · Posted: Sat Sep 16, 2017 10:35 pm Post subject:

If the switch is open meaning when measured with an ohm meter (with the wires disconnected) you are getting a reading of infinity, the switch is not asking the fans to run.

This means:

1) the coolant has not gotten hot enough to close it.
2) the switch is bad (unlikely)

My next step would be to (with the ignition switch on) connect the 2 radiator sensor wires together and see if the fans run.

Try this and check back for more help.

BTW it is common for the temp gauge to read high on these cars due to dirty grounds.

Ok will try Monday but it was almost to the red.
This was the first time coolant was back in the car also
And the thermostat opened I topped it up

I will check the sensor and try the jumping item
To test the fan

Make sure you bleed the cooling system if you haven't already. Air pockets will cause overheating.
