We got spark and fuel pressure-my question here is it the correct fuel pressure EFI system don't like low pressure and also are the injector/s pulsing

Spark and Fuel pressure and injectors are okay-Check the valve and ignition timing report back with some results

No too familiar with this model might want to check it for an access panel under the seat or the trunk if not it has to come down.
