1994 Other Cadillac Models engine

Dunno what model ? but I'll give you something without the electrcial diagram for your starting system

Your problem could be fuses/ignition switch/park and neutral switch/starter enable relay-

the pwer on the goes on but the engine wont crank over we thought it was the starter but we took it in and it worked we still don't know what it is[/quote:e6ac706be2]

take the cables off the battery and ck them for green stuff on them, clean them good, ck the purple wire at the starter for power with a test light, when you turn the key too crank it, it should power up the test light
