Well my Capri is dead again but at least I know why it won't start this time, the fuel injectors aren't receiving their electronic signal to fire. The ecu, distributor electronics and map sensor have all been tested, the ecu and map sensor are both ok and the dizzy electronics was inconclusive.
My prime suspect at the moment is the dizzy electronics because the seals have failed and oil is leaking into the dizzy. But I was wondering if there's anything else worth checking out that could cause the injectors not to receive a signal?
