Ok so I posted a while back about a problem I sometimes had with hard starts and some white smoke coming out the tail pipes on occasion. I will re-explain my situation. I can go out to my truck sometimes, no matter hot or cold, and turn the key and it doesn't start or either it starts and bogs right off. Then right after that I can turn the key again and it starts right up. This doesn't happen all the time, and it's not just when it's cold or just when it's hot. Sometimes white smoke will come out of the exhaust, about 2 seconds after starting it you can see it in the side view mirrors, so it is a noticable amount. But this doesn't happen all the time either and doesn't occur specifically when the starting does. I have noticed on the inside of my exhaust tips that it has turned an orangish color, which points to water/moisture. My question is, could this be a SMALL crack in the head gasket? I have been told it's a fuel pump issue, but I find that hard to believe. I don't have antifreeze in my oil and my coolant light has came on 2 times in the past 3 months but I just finally filled it, it only needed about an inch or two in the fill area. Another note, my exhaust is setup true duals, so one from the left cat, and one from the right cat. I haven't noticed smoke coming from just one exhaust pipe, it seems to be both. If there was a cracked head gasket, could it be in a place that would affect both sides of exhaust? Just trying to figure out what is causing the starts and white smoke. Thanks for all your help in advance.

I also tend to think it would be a fuel pump or fuel flter issue. When your truck doesn't start or dies immediately, then starts right up after the switch is turned off, it sounds to me like you're actually "re-priming" the fuel system. My wife's car does that sometimes; after it's been sitting overnight, you can get in it and crank and crank and crank and get nothing. Then you turn the key off and right back on and it fires right up. Hers is the fuel pump, because I just changed the filter. As far as the smoke goes, I'm a little clueless on that.

if you have full dual exhaust and are getting white smoke out of both pipes, then your problem is not a head gasket unless both are leaking. i would be looking for a leaking intake manifold. if you overheated the engine then possibly both head gaskets.
