I have a 2001 clio privilege 1.4 and it suddenly will not start 1st time. It turns over fine but feels like the engine is juddering slightly as if it's trying to get fuel? I spoke to a breakdown engineer which said press down the clutch & accelerator together and turnover for 8 seconds and it did start he said could have been air in the fuel line but this is happening regular now and not good for the battery. Is it the fuel pump? Please advise to the problem.
