Thanks for the ideas i am checking some today ! A lot of these commin suggestions have been checked as listed in first post and replaced just in case for example fuel pres reg and filter.
Please keep following this for input man!

What's the best way to check
Computer?
Low volts ( I have a small oddesy batt, so maybe this is a prob)?
Grounds?
