    92 960 328000km(about 200000m)bi-fuel(lpg gas/petrol)

    no spark on cylinder #2
    have exchanged from running other 92 960 :

    ecu,coil,amplifier module,flywheel sensor,cam sensor,sparkplug

    have checked wires from ecu to amp on manifold,amp to coil all ok

    14v on coil with running engine also enough power to light up a 21w bulb

    checked signal on ecu for plug #2(wire #13) and nothing all others ok

    i have soldered a wire directly on the pcb to check the signal,but its to
    dark now
    and my flashlight just died,so i will check that tomorrow

    any help is welcome

    ground at ignition amp ok because the two other cylinders work

    no break in the wires,same result when i measure resistance between ground
    and pin 13
    with no ecu present on both cars

    If I understand you correctly, you have +12v and ground at the ignition amp,
    but you have no LT trigger signal from the ECU??

    If you have swapped the ECU for a known working one and still no LT to plug
    2 then you must have a break in the signal wire between ECU and amp???

    And you know there's 2 amplifier modules and IIRC the rear one does the
    front cylinders?

    only 740 and 960 unfortunately
    i could use the schematics of a 70 series too since my brother bought a c70
    nothing is wrong yet,but how long will that last?

  8. Have you tried the Chilton manual number 72302? Available from IPD and
    probably most high street motor accessory shops.

    All the best, Peter.
