The piston rings are probably worn or worn valve seals allowing seepage of oil past them. When the engine sits, oil collects in the cylinders and burns with the fuel when started. This explains the smoke at start up and acceleration. On the electrical side, check the fuses. It could simply be a blown fuse or fuses that is disabling the windows and door locks.

I'll check on that thanks for the reply. I'll post if I find the problem with you're help. Thanks


Black smoke is usually a sign of too rich of a mixture of fuel because of injector or ignition problems. Blue smoke is a sign of oil burning.

Ytlas is correct. Black smoke is too much fuel. HTH. -Jim
