ECU reads 0V on all sensors

[Galant_martin]

Hello,

I have an eprom ecu board here with an strange problem.

TMO logger can Connect with the ecu.
I See „federal ecu“ in the first screen, I can switch the fuel pump on.

One driver ic is bad
, I think it was 105, is dead. But i have no isc so thats no problem

But car wont start. Battery reads 0V, and all other sensors reading 0V too.

On pin 23&24, sensor +5v and sensor ground my multimeter tell‘s me 4,98V so i think that‘s okay.

Where can I look next?

Thank you all and a good new year

I can only suggest to double check and make sure the ground wire connection is clean and making a good contact. Also maybe undo and reconnect the two main connectors and make sure they click in place.

Other than that, try and seek a ECU repair shop. Not sure if you want to ship to the US or not, but we have these guys. http://www.ecmtuning.com/
