I went to look at a 98 Ram tonight. The seller said he drove it, shut it off, then it wouldn't start. He used 2 battery packs and was able to get it started for about 2 minutes while gassing it. Then it shut off and he wasn't able to start it again. I tried my battery pack on it but it didn't start. I'm wondering if I should take a chance on it for a very good price. What's the worse it could be? Oh yeah, the oil seemed very black but very thin also -- not thick like I'd expect it in this 25 degree weather. What could cause that?
