Td4 non start please help

Hi guys

Ive got a 2003 td4, it was running sluggish, with a little smoke on first start until warm then no smoke, it wont rev over 3000. Was advised to remove fuel pressure sensor and try it, but it wouldnt start, so I plugged it back in but now it just cranks over
Any help most appriciated
