Brava no spark (1996 1.6)

Hello Friends,

I got new problem with my Brava. There are no spark, so I am not able to start the car. There are no problem with ignition coil, problem is elsewhere.

One strange thing, what happened together: when I turn on the ignition, main cooler fan starting to rotate at full speed and stops when I turn of the ignition (car is absolutely cold). I am not sure, that both problems are relative, but it happened in same time.

Where can be a problem? Something with ECU. I tried to connect laptop to 3pin connector, but with no luck (no response from ECU). I have other Brava (1997 1.4) and can connect to its ECU with no problems.

And second question: does main fan working only with ignition on Brava 1996 1.6? When my other Brava heating, it working with or without ignition.

Thank You

Re: Brava no spark (1996 1.6)

check the battery, starter motor, fuel lines maybe? Fan operating on ignition can be due to a wrong signal sent by the ecu, or your themo malfunctioning or a wiring issue.

Unplug the ECU and clean the pins with dry cleaner spray..
Starter motor need a check, if you can run the car by pushing it or sliding it,then starter motor is the problem..
Last if ecu cleaning affect nothing,you need to inspect fan relays.
