The starter's mechanical 'relay' on a 90's caddy it attached to the starter, it is the solnoid and may be defective. Check your connections and harnesses for the smaller wires going to the solinoid. There probably is a standard electrical relay under the hood in the power distribution center, and it should be marked either in the owners manual or the top of the center lid itself. You can swap it out with another standard relay not needed like your ABS or horn relay to see of this is the problem.

My 99 monte carlo wont start the lights and radio work but the car wont start what do i do


If you have power but the starter won't engauge here are a few things to check 1 start at the fuse box check fuses. If the fuses are good check the starter. This time of year cold weather starters have more strain and burn out easier. Also exessive oil dripping on the starter can cause to go out because of residue build up in the starter. If the starter checks out good it is then a bad conection or wire. thanks

My 1990 Cadillac Deville wont start or engage starter


Sounds like you blew fuse. Fix fuse and borrow a car starting switch they use at car repair shops. As long as you can turn tumbler to on ,you can start using the starting switch from repair shop..There should be a way to run a start button to start car and your off/on key should be OK
