We recently bought a 1994 GMC Jimmy from someone and it appeared to be a great truck. My husband took it for a test drive, tested out the 4 wheel drive, there were no problems at all with the truck. About a week later, once we got it titled and in our name it started having issues. The first thing we noticed was a good bit of white smoke while was driving. It's not constant, it just does it for like 30 seconds, then stops. It does it every now and then. When my husband was driving about 75 and let off the gas, the engine was still revving high and then slowed down. He said it was a loud whining sound, he thought the engine was going to blow. Then he started having troubles starting it. He would turn the key and it would make the cranking sound but it would take forever for it to start. Now today the battery light came on. We have had the truck for all of maybe 2 weeks now. What needs to be done and what are we looking at paying? Thanks in advance!

White smoke from an exhaust is usually an indicator of coolant leaking into your combustion chambers (cylinders). This could be from a leaking head gasket, or even a cracked engine block or head. None of these are simple repairs.
Check the oil dipstick and observe whether or not the oil has a 'chocolate milk' appearance. It should be dark, but clear.
If the oil looks milky or frothy, you have coolant leaking into the crankcase as well. If this is the case, do NOT drive the car, since antifreeze in the oil can quickly ruin bearings.

"When my husband was driving about 75 and let off the gas, the engine was still revving high and then slowed down" The Throttle cable may need cleaned. Its probable sicking. I had the same problem with my 93 GMC Pickup.

Sounds like a blown head gasket at the water jacket, and coolant is getting into the cylinders.
It may have been overheated a time or two.
You could be looking at a repair bill of $2000 give or take.
