My 1994 Toyota 22r engine will not crank. the battery is charged and fully connected. i will put the key in the ignition the whistle will sound all of the lights will come on but as soon as i turn the key to the start engine position nothing happens and then once i put the key back in the whistle will not sound. so every time after i attempt to start the engine i have to mess with the battery terminals. has anyone else had this problem and if so can you offer some help Please.
