Hi,
Just bought a car with an autronic sm4 in it. I was tidying up some wires (heatshrink and solder instead of twist and tape) and now the car will not start. There is no fuel or spark at all. I can't hear the fuel pump either so it is like the ecu is not doing anything. When I hit the start button it still cranks over so the starter fuse and relay are still good.

I have checked and there is still power in the main red power wire at the SM4 end. Any ideas on what to check next?

Thanks
Chris

Pin 1 12 volt Ign Sw and Pin 29 Ground. Do the error light come up and can you communicate with PC & Sm4?

Ok, will check them next.

I can't connect yet as I am waiting for a com to usb adaptor.
