E36 318I NOT STARTING

[lockey]

Hi,

Ive got a BMW E36 318i Cabriolet.

The other day the coolent temperature suddenly rose very high and the red light came on. I pulled over at the first chance. When i looked under the hood a pipe had become disconected. The one that connects the engine to the coolent expansion tank. I re connected it and toped up the coolant once the car had cooled down. This was fine for a few days untill the same thing happened again. I then realised that the mount on the engine that connects to this pipe had snapped of and smoke was comming from the pipe. I have replaced this part but now the car wont start.
It turns over fine but wont kick in. Does any one know if this is because the computer has sensed a problem and is stoping the car starting? Or if there is another reason. I am hoping it hasent caused the head gasket to go but can't tell without starting the engine, even if the head gasket has gone should the car start?

HELP please

To be honest with you... if you lost a considerable amount of coolant... I dont know how far you drove afterwards... but if some or another got really hot.. and expanded or bent due to heat... It might have just froze up once it cooled down over night...

Honestly.. the best thing to do is probably talk to your nearest BMW dealership... and ask them what you should do... they might be able to tell you if its a computer thing.. or mechanical... GOOD LUCK!
