bloody car is cracking me up now ive had a new phase sensor fitted new cranck sensor new leads new plugs, and ive had the car set up at MAD that was summer last year and he got it running spot on, its been laid up since september mostly outside now it wont start, theres fuel getting to the front and a spark but i think the spark is very weak. as when it does finally start it'll run but not well and as soon as you touch the throttle it cuts out.when it cuts out theres an arcing noise inside the distributor HELP
