GMC Repair: battery, diagnostic port, auto zone

Question
i also been having problems with my van its a GMC and well when i turn it on it does not work it sounds like its about to start then it does not i do not know what to do !

Answer

logo go to Wal-mart and ask for a battery diagnostic. Would be better if you ask for a starting system scan/diagnostic. this is free of charge. it will tell you if your battery, starter, and alternator are normal or weak. if you have access to a scanner do that too. there is a diagnostic port in the lower portion of the dash. a cheap one is 30.00 at auto zone. if you are uncomfortable doing this...auto zone will do this for free and give you the codes. if need be, email them to me. the codes will get you very close, but usually will not pin point the problem.
