Hi,

My 05' Civic (1.7) started to all of a sudden die while driving (very intimidating) and there is no CEL. The car will start up after I put in Park and turn over after it has died. It does not do this when the car is cold meaning for the first 15 minutes of driving or so. When driving for 20+ minutes, it can randomly die while car in in D and I'm driving normal.

I read that it could be a loose ignition switch but I tested as stated (car on in P and move the key) and it does not cause the car to stall/die.

Anything else I can look for?

Thanks in advance

 

Check timing and the main fuel relays behind the glovebox.

 

Do I replace them both or can they be tested?

 

They can be tested for continuity first before deciding to replace them.

 

Test the alternator while running , you should have 14+ volts .

 

The alternator tested ok.

Switched the two fuses as stated but the car still dies (maybe a bit better; takes longer period of time before the car dies).
