OBD LED always glow in socket 2# Volvo 240 91
 

Hi everybody,

I´m Martin from Montevideo, Uruguay.
Sorry for my bad english, I will do my best.
My Volvo 240 1991 won´t start. I have both pumps direct connected and I have spark.
Check for OBD codes and socket 2 allways glow when I get key in pos II. Socket 6# gets 1-1-1 (fine).
I didn´t check the timming belt aligment yet.
Any ideas?

That red led doesn´t let me sleep.

I had a similar problem recently with socket 6. The LED just glowed permanently whenever the ignition was turned on. It turned out that the EZK unit (Ignition ECU) had failed, which is what socket 6 tests.
For socket 2 it sounds like your LH2.4 fuel ECU has failed.

I have the 3.1 injection. I guess It must be a similar problem.
Any advice to trst the ecu and confirm that?
