somebody please help me - i just bought this 1992 trooper today - when i went to look at it - it was immaculate inside and out - no rust - started right up no problem - droove nice and smooth - seemed like an excellent vehicle. I drove it 45 miles to get it home and it ran like a champ - i was sooo happy. when we got it home it sat for about half an hour then i went out to admire my new vehicle so i sat in it with it on and idling fine for about 15 mins (i live in maine so it's cold - i had to have the heat on) anyway.... about a half hour later someone came over so i went to show it off and just when i was bragging it up i went to start it - it sputtered a couple times and died. i tried a couple more times and it did the same thing - and now it won't start at all. it turns over and over but will not start. the check engine light is not on - any hints on what we should check first?????? i'm so sad - please help =(
