I'm having a problem with my civic once again unfortunatly :cry:
I have gotten a check engine light a few times...
And i scanned it again this time OB1 style the light blinking and got 4 long and 3 short flashes wich indicates


CODE 43 - Fuel system (except D15z1) (not sure if mine is aD515z1 (93 civic HB 1.5 SOHC 16valve)

and i'm just wondering is there anyway i can test out my fuel system or should i replace the whole fuel pump (never been changed and has 324 000KM on it)

Just wanted to know what you guys have to say about this.

your fuel system does not only include the pump. it's a general code that gives you an area to start testing, it does NOT mean your pump is bad. the pump is one of like.... prolly a dozen subsystems with hundreds of individual components.
