1.8 turbo wont start , no spark on coils neither fuel pumps works help please

[Val]

Do you read wiring diagrams?

[kninio]

i will read them now , so which i must check exactly? for the coils and for the fuel pump?

[Val]

i'd start with "+" and "-" that goes to ECU and fuel pump relay.

[kninio]

ok ill check those and let u know

[kninio]

vag com wont connect to ecu??? why is that? but i could to abs and others

[ManiacuV6]

IF you cannot connect to the engine hence you have a problem with ecu or supply to the ecu. You can check the 12V , GND and the 12V supply through ignition . If all are ok you have something wrong in the ecu.

[kninio]

which one is those in the diagram? i couldnt understand them well

[ManiacuV6]

Pin 62 from ECU you should have 12 V . Pin 3 you should have 12 V with IGNITION ON.
PIn 1 and 2 you have ground.

Check all the wire using a bulb of 21 W .

[kninio]

u mean i check those pins from ecu in the paralel side in the plugs right?

[ManiacuV6]

So you disconnect the ecu from connector . After that you count the pin and measure what i told. Easy peasy

[kninio]

i will do that in weekend , i bet its some wires ecu cos they turn it off and didnt power anymore , i dont think ecu had heart attack while sleeping. i appricate your help really

[kninio]

dude does the auto data have wiring diagram for the ATC ecu? cos mine doesnt have immo , while auq have it.

thanks in advance

[Val]

Autodata dont have ATC diagrams.

[kninio]

aha , but the +V and -v is standard in auq and others 1.8t ?

[ManiacuV6]

THe witing harness for 1.8 T is fairly the same on cars with drive by wire throttle . So you won't do anything wrong. USe the AUQ wiring from Autodata. Good luck!
