hi ya, iv got a 172 phase 1 and over the last couple of weeks iv had problems starting my car. somedays it starts fine turn of the key but seems to be getting more often that its struggles starting, it turns over fine so battery and starter motor is ok and recently changed plugs and leads, iv noticed that when i turn the key so the ignition lights come on the sound of the full pump coming on sounds weak so i swapped the really with another one but still no better. the relay did look a bit green. any one got any ideas? also where is the full pump on these? thanks for any help!
