Ok i check for a 91' Z24 for cheap but it doesnt have electricity on(like no batterie). I tried to boost but it stall after 30-40 secs...The proprier told me than that's the Fuel pump?! A bad fuel pump can remove electricity on a car?!?!?! Anyone has a idea? I told him than thats normal no electricity=injector wont working...I think about the battery or alternator...?

its definately an alternator problem, and/or battery, but definately the alternator, the car wouldnt start if its the fuel pump while boosted

Well first off it is not a good idea at all to run your car without a battery. The battery filters out all of the power spikes that could fry your ECU.

Secondly, it sounds like you need a new alternator. Remove yours and get it tested at any Autozone (or other parts stores)
