Yesterday i got home with my civic and parked and went to leave 30 minutes to an hour later and it would not start , cranked fine , could hear the pump priming. I left it and came back a while later and it eventually started. Then this morning it started fine again but I did not drive it ,then by the afternoon it would not start again . I came back to it a while later and cranked it a few times and it eventually start again. Does anyone know what the problem could be ?

 

Is the motor turning? How much mileage? When was the last time the plugs and the coil packs were looked at?

 

The motor is turning , roughly 140k kilometres. It's been a while since the plugs and coils were changed not sure exactly how long. Today my girlfriend went to take it to work and immediately it started to overheat and is blowing only cold air from the registers. Now there is a puddle
Of anti freeze under the passenger side of the engine.

 

Check the intake gasket on the head. Might have blown the gasket. Or water line, clamps might have failed.

 

It may be because your starter is starting to wear out. When you turn your key, an electromagnet forces the starter gear to engage the teeth on your fly wheel. The motion of the starter gear sliding forward into the fly wheel also engages electrical contacts which give power to the starter motor, spinning the starter gear and starting your engine.
