Car slow to start from cold - already replaced glow plugs and glow plug relay!
So for the past couple months my Alfa GT 2004 has had a couple issues getting going. Some mornings its fine, others, especially when its cold, it struggles to turn over, I keep the key turned but it just chugs and bit and doesnt kick in, I sometimes have to try a few times and give it some gas before it gets going.
It's worth mentioning, that when I put the ignition on, the glow plug light only stays on for a second or two, is this normal? In fact, after the first time, the glow plugs only stay on for half a second.
I've had the glow plugs replaced as well as the glow plug relay but its still the same, I get the impression the glow plugs should be staying on for longer but they are not, what could cause this?
Probably also worth mentioninig that the engine management line is on a fair bit of the time, i've read the code its a camshaft sensor fault!
