206 1.4 hdi non starting

[jr83 1]

Hi I've got a 206 that has been off the road for a few months. Yesterday I started it up via a jump pack to move it on my drive. All started fine, when I went to move it back an hour later it started up via jump pack but as I got out to remove jump pack the car just cut out and now turns over but doesn't fire. Any suggestions? The battery has been fully charged yesterday(battery 12mnths old), did the beep test with the key in ignition and it beeps with drivers door open. Help please!!
