1999 AUDI TT Starting Problem

[ngakson2002]

Hello Mate,
I have here a 1999 AUDI TT that will not more start following the battery that was removed with the Key at ON Position in the Switch.Furthermore, when the key is ON, the security Light will go OFF but car is not starting.
Can someone help me with the procedures to be followed to restore starting of this car?

Best regards

Hi
I would rule immo, it should start the car for a second and then off.

I would suggest checking the throttle body for carbon build up. If its dirty, take it off and clean it with carb cleaner then put it back on and turn ignition on for about a minute before you crank the engine.

Reading data and codes in ECM is a good point of start. Check spark and inyector pulse too if all ok see fuel pressure.

Hello Mate
Engine cranks well but does not start.Updated informations about it is that battery terinals were reverse when fitting the battery.Sure this action most have blown the Engine ECU
