Starting problem

[shanem]

I have a 2000 puegeot 406 hdi 90 brake. I got the clutch changed in it a while back and since then it wont start with the key, the starter turns over but wont start, it will roll start however and runs fine. The injectors have been checked, compression is all ok and apparently it's not the crank sensor either. Any advice would be greatly appreciated, thanks!

check the earth on the gear box and the feed to the starter
