We just aquired this toyota truck and figured out an electrical problem to get it started. Now that it starts it pulmes out a big white cloud of smoke from the exhaust, that smells like gas. We don't dare drive it, should we? The engine sounds good, what do you think it could be?

If its not condensation-its burning coolant maybe a blown headgasket crack head or block

Have it block and pressure tested-do the block first to pinpoint a combustion leaking into the cooling system or a gas analyzer to sniff for hydrocarbons at the radiator fill neck.

Pressure test: do not do a pressure test if there's leakage at the headgasket this might cause coolant into the cylinders and lock it up or bend a connecting rod if cranked thereafter. The headgasket should be repaired before doing the pressure test.

If the block and pressure test passes check the following: Thermostat,Pressure test the Rad. cap,Clogged radiator,Fan clutch,Radiator electrical fan,collaspe hoses,water pump.
