Today, I replaced all inlet, throttle body gaskets injector seals in my g6e turbo. Afterwards connected the battery started the car and no tacho.. everything else on the dash works. Anyone come across this? Or have any ideas of area I can search?
Where does signal come from ? Coil wire or cam angle angle sensor?
Back of the inlet there's a single wire (pink green) little black box that bolts to the rear inlet brace, not sure what it is
