I have owned this vehicle for a little over 4 yrs now, and it has been a reliable ride until recently. It has now gotten where over half the time, you cannot get it to crank. It seems like it will do fine for a few hrs, then not start for an hr or so sometimes. Here are a list of recent repairs made over the past few weeks trying to resolve the issue: -Timing Belt Kit -spark plugs -a/c belt -Serpentine belt -plug wires -fuel system tune up -fuel system service -valve cover 1 -r&r coolant temp. sensor These were all repairs done at a local Gateway. Now 3 weeks and almost $1200 later, it still has the problem. Any suggestions would be greatly appreciated, Thanks in advance.

this is strictly "curiosity" question. does anyone KNOW why half ton trucks, their heavier duty brethren, and related SUVs turn on cooling fans at cold engine startup? isn't the point to WARM IT UP, instead of cool it down? gmc, f-ord, dodge - all do this. sound like tanks at start up. relays click, fans kick in, whole symphony. why?:confused: :confused:
