well here is my problem
i have 98 gmc jimmy.
the day we were driving back from college
it just shut off and we can not get it to start
we have tried scanning it with our code scanner
but it comes up with "no codes". my dad put something
in it to make it start but only for a sec then it shuts right off
it acts like it wants to start it starts to turn over but then just
dies! Does anyone have any anwsers? please HELP!!!
