I just bought a 97 boxster that had a bad intermediate shaft bearing. when i bought it from the previous owner he had already pulled the engine but decided he didnt want to mess with it any further. i replaced the bearing and put the car back together and when i went to turn it on it wont start. it wont turn over or anything at all. the dash comes on and it does a three second countdown for oil i think. everything electrical seems to be in order as far as lights dash a/c etc. the only thing that seems odd is that im not hearing any relays clicking. my first thought is that i missed hooking up a relay but im pretty sure everything is connected so i dont think thats it. is there something that gets triggered when i took the motor out that i need to reset, or is this likely to be completly different problem that i didnt know about before buying. any and all feedback is greatly appreciated.

 

Lets get back to the IMS bearing first. Did it fail, or was it getting noisy and just needed to be replaced? If the bearing failed, and you didn't check the cams, etc then you will have serious issues.

But, if the starter isn't engaging at all, then there is an issue somewhere else. Did you remember to hook up all the ground wires, and electrical wires correctly?
