,but will cause starting issues. You might have a air lock in your cooling system, tell me this if you run the car for awhile get it good and hot does it act up? Loss coolant, overheat, and not start?
Sounds like it could be main relay to me also.
I think your starting problem and loss of coolant are not related.
Is there any coolant in your oil?
