My 2000 Ranger 3.0 flex vin v has no spark after replacing injectors. Coil, spark plug wires and plugs are new. Replacing injectors was next step in fixing a cylinder 5 misfire. Checked all fuses, all wiring harnesses and plugs. Have good fuel pressure and took out plugs to make sure not flooded. Any ideas on anything i missed or did wrong. It had spark prior to replacing the injectors. Thanks.
