Default Volvo 740 no spark

740 B230F

The engine is not starting and is not getting any spark.

I have replaced
- sparkplugs and wires
- coil
- distributor and rotor
- ignition module
- crank sensor

Do you have 12v at the coil with the key on? Do you have a flashing test light on the other coil terminal when turning engine over? Do you have 12v on one terminal at the injectors with key on? Does your car have a black 4 terminal noise suppression relay mounted on the left inner fender as pictured below? (If present that relay sends power to the coil and the injectors)

I have 12v at the coil with the key on, and i have a flashing test light when turning engine over. I also have 12v on one terminal at the injectors with key on. The car does not have a 4 terminal relay.
