Pug 205 injector problem

    I have an electrical fuel pump in the 205 and it only fires 3 injectors at once, I have tried 8 spare injectors I have, they cant all be broken!!

    Could it be an electrical problem? No matter what way I switch them on the fuel rail, 3 only works, but its all ways the three same injectors, none of the other 8 work for me!

    Any ideas ?

    I fail to see what having an electrical pump has to do with your problem.

    A "Noid Light" or a test lamp/diode or DVM is what you require.

    Depending on system construction, you have 1, 2 or 4 coil drivers in your ECU, but given as 3 are working I'll have to assume 2 or 4.
    If 2 a wire, fuse or connector is faulty, if 4 a transistor driver is faulty.

    First determine if you have a common 12VDC or a Common ground. Ie with the car running you get a constant 12VDC on one wire to the inj and a pulsed ground, or a constant ground and a pulsed 6~12VDC. A wiring diagream would tell you this at a glance.

    Once you figure that out we can go to the next stage.
