Just sent a set of Beiges off to be cleaned/refurbed. Got them back and fitted them, now the car won't start... In the paperwork with the injectors it said they were all fine and that sometimes they stick after cleaning, so to tap each injector on the metal body if this happens, i have tried this and still no luck...
The car fires on 2cylinders and then cuts out, injectors 1&3 are not firing. Should i remove the injectors and spray a little wd40 through them to free them off?

Cheers
