    new member, 1990 GMC Jimmy full-size

    Hello all, I just found this site and I hope it can help. I have a 1990 GMC Jimmy full-size that I am having problems with finishing it up. I followed ALL the recommendations from Brian at TBI chips. SO, I bought the 4 bolt vortec 350, lunati cam, etc.. It will not run. I can start it and once it goes from closed loop to open loop it seems to start flooding and dies. I also had some over heating issues with the stock thermostat so I dropped it to a 165. Anyways, I did go back to Brian about some help getting this sorted out and he is not able to help. If there a starting point to trouble shoot this thing, I sure would appreciate any help. Right now all I have is an expensive piece of yard art. Thanks, Dennis

    Hi Dennis:
    Welcome to the forum. I'd start by downloading Tunerpro. Info to do that is on the forum.
    Good luck:
