Help Mk3 Galaxy Not Starting Every Time

[Flatty01]

Hi all, my 2007 galaxy mk3 is not starting every time. Tries to start but doesn't fully turnover. It's been to the garage and had a fuel pump replaced worked for a couple of days and stopped and still not working every time . Garage today suggested starter motor but still the same after fixing and so far £1200 wasted. Going back tomorrow. Any ideas as it's not every time. Really annoying so fr. please help

It seems very quiet on here lately and I'm no expert on these. The description is not over helpful but try starting from basics. If it struggles to turn over and taking into account it is now Winter  the first thoughts go to battery. If you've spent all that cash I should expect someone has checked but who knows.

 

In the absence of a meter do the lights go down when you try to start it could be poor connection, defective starter or just battery - check battery by replacement if necessary, maybe someone has fitted an underrated battery.

 

If the terminal voltage is low the glow plugs won't work well, the starter won't work well and the fuel pump won't work well and you have the very problem. Do the battery terminals get hot when trying to start it?

 

Until you have got past all of these you are just wasting time and money.

Could also be the immobiliser is still active as the key chip hasn't been detected. I believe engine will turn over but not fire but not 100% sure.

After getting the "immobilizer active" message today in my Galaxy I can confirm the car won't turn over if it's still active. You get nothing / nada / zilch!
