Would not recommend using easy start, it sometimes causes more problems. It would appear that whatever the fault is it is being signalled through the ECU (engine management system).

The ECU is not allowing the injectors to release, hence non starting.

Without codes showing it is a difficult problem to resolve. It could be a number of things ie Faulty pressure regulator sensor, faulty injectors(is there any black tar around the injectors?), injector wiring harness(check the electrical connections are good and making contact).
