my fd dosent want to start. the starter turns over the engine but wont start. but the strange thing is that when we push start it it starts right but and stays on... the voltage is good and it has a new alternator i really have no idea whats going on any one could point be in the right direction ?

 

Check compression.

Make sure the CLT has not failed and caused the ECU to always think the engine is warm. Does it start with the key when warmed up?
