I have a 93 GMC extend cab 1 ton daully , it used to be 6.5 turbo diesel . It has had 3 diesel engine in it and they are known to break cranks . I changed it over to gas and now have a rebuilt 5.7 TBI in it , it has 31,000 kms on it now and ran beautiful until 3 1/2 weeks ago . Now it over fueling and blowing black smoke out tailpipe , runs like crap . I have change everything I can think of , but have not put a scanner on it . I don't think a scanner will do much for me because of my wiring , it's still diesel wiring under the dash and diesel don't have computers in this yr of truck . I've put gas wiring under hood and a computer in it now , is driving me crazy trying to fiqure this out . Has anybody out there got any suggestion , HELP PLEASE .
