Laguna won't start or starts for a second only?

Hi i am new to the forum, i have car eperience from years ago.



Help! i have a Renault Laguna 2.0 rti petrol 1999 with a problem starting. Last night the engine fired up for a second then died. The new halfords battery fitted earlier this year has been struggling for a while, ever though it is correctly rated. So the car was now flat. I jumped it with leads and it fired up as normal. This morning the same thing happend so a repeated the process. I drove too the local cash machine and switched off the engine. It happend again only this time it will not start. I have fuel in the tank. I have taken the plugs out and checked for a spark which, was not evident when earthed i even held the plugs by had from each coil pack. So its the crank sensor right? i have taken the crank sensor off and it seams ok externally no metal contaniments.



The fuel pressure seams a bit lazy too. I took the dust cap off the fuel rail and depressed it and fuel ran out. i tried this again after a good few cranks testing other parts and none came out. The car did start evenually for a split second again this morning and the fuel presseure on the fuel rail was back. Could i have a intermittent fuel problem with the pump? or is it immoberliser related? (coil packs?)



I hope this is readable as time is frantic!

Come on forum gurus, its a tea break quiz!

Regards
