my golf suffers from poor starting hot or cold. just cranks and cranks... heres the BUT , it fires and runs with the startor motor? so once key released stalls or nearly stalls unless you apply full throttle . no fault codes or performance issues just poor starting.

i suspect either fuel pump timing or ignition switch fault . switch is fault anyway as have no radio signal wire or its intermitant.
could any oone shed any light on this ? or has any one got a wiring diagram of the 50 / 15 signal to the pump/ecu?
many thanks XX
