Hi, puzzling problem, 2.2 crv ex diesel starts great in winter first turn of key no problems. In summer however different story, does not like starting. Have to keep ignition key turned for a second after it starts or it cuts out, plume of blueish white smoke, clears up and runs perfect from then on. When engines warm starts fine. Have changed glow plugs recently and glow plug timer relay.
110,000 miles, no loss of coolant or oil, using 0- 30 fully synthetic oil. Fuel air and oil filters changed every 10k.
Any ideas?
