H all, i have found some good pointers on this forum so far but cant find the answer to this problem. My 2003 laguna 1.8 16v was starting fine until my mate changed the clutch after which it takes 3-4 seconds before firing up. This forum pointed at the TDC sensor which i changed and then also the connector but niether have solved this (i now have three TDC sensors) Occaisionally however it will fire up quickly but this is always followed 30 seconds later by the yellow engine warning light flashing indicating excess fuel. I was also experiencing the engine missfiring at times and cured this with new stick coils. Air filter and spark plugs also changed. Could it be another sensor issue? Would a faulty lambda sensor cause poor start up? I have also read about possible engine coolant sensor issue. Any ideas much appreciated thanks.
