Hello I'd suggest checking over the injector wiring as this sounds like it is damaged and shorting all 4 injectors outalso ther should be a couple of small earth connections that run out of the wiring loom and are secured to the engine with small bolts and ring terminals. these need to be bright, tight and clean
