Hi I am new forum, my 307 1.6hdi was bit jumping, so I went look everything found that EGR making thick black grease carbon block inlet manifold. I have cleaner and put manifold back and tight up injector pipe nut and renew fuel filter. Primer little pump on top of engine and turnover it won't starter and drain the battery very quickly. I had to recharger over night top up to 13.8 Volts and try again turn over and primer so many times still won't start I am out of idea. None fault codes, all pipe fit exactly same place and all connect is fit.
