Hi everyone, I have a Chrysler 300 estate, it’s been hard to start past 4 months, been in twice and all glow plugs have been replaced, but it still won’t start first time, sometimes it can take 3 to 4 attempts, lots of white smoke but is fine after and starts first time every time that day!!
what is it that is stopping it starting first time in the mornings?.

Hi Gavin, 

If you've had it into a garage twice, it's surprising they didn't check this out for you properly. Too many things could be giving you the issue, and it's a process of elimination.

First I'd be checking battery and connections. If coils have been done, then starter motor and also making sure fuel pump is working.  The white smoke could very well be a coolant leak. Defiantly something any decent mechanic would diagnose and sort you.

Thanks MrZammas

yes a process of elimination for sure, problem being it starts first time all day long after it’s first start. If the fuel pump was not working properly and hence not sending the correct fuel pressure to the glow plugs, why is it starting every other time, even if it’s 10 hours between starts same day it starts?
 

The starter motor is cranking over well by the sounds of it, no labouring there. I thought the white smoke could have been to much fuel by the time it started. Wondered if as I keep cranking it over it finally get the correct fuel and starts, but It still doesn’t answer why it works for rest of day then! I don’t expect it could be the injectors?

I'm thinking it's still an issue with the fuel system. Perhaps the fuel pressure regulator/gauge. Takes time to get the fuel where it needs to be to start, once there it maybe okay for most of the day. Sit for say 12hrs, back to square one.
