Cadillac Allante won't start with no power to starter and windows on Cadillac Allante

Some Cadillac Allante owners report experiencing starting issues characterized by a lack of power to the starter and windows. A common cause for this problem is a dead battery, which can prevent the vehicle from starting altogether. Additionally, some owners find that a faulty alternator may lead to insufficient battery charging, further contributing to the power loss. Problems with the ignition lock cylinder can also result in a no-start situation, and checking the resistance on the keys' resistor may help diagnose this issue. Furthermore, fuel system problems, such as inadequate fuel reaching the engine, can hinder the starting process, prompting owners to check fuel rail pressure and spark plugs for proper function. Troubleshooting these potential causes is crucial for identifying the exact reason behind the starting issues in the Cadillac Allante.
