No singal to injectors
Can't start the engine on my S80 after putting the injectors back in, as well as the cover to get access to the swirl flaps. At first I thought I might need to bleed the engine of air in the fuel systems, prime it but checking some more there seems to be nothing coming the injectors. Nothing coming from the noid lights confirm this.
Anyone know what the most likely issue is and where to look? Looking around most people say either ECU or wiring. Is there a best way to test myself if these are the ones not working?
Fixes even if one of these are faulty? Could battery be too low so the signal is prevented from being passed? What's an ECU replacement like? Is there some sort of reprogramming needed and if yes, why?
