   I've got a 99 saxo vtr that i've had for a week. It seems after you've had it out a run (even a short one) and switch it off, if you go back to it within a couple of minutes it takes a quite a bit of turning over to get it going. This doesnt happen all the time, sometimes it'll go straight away. The previous owner has had a new downpipe fitted and the gaskets are leaking. Im fixing these myself tomorrow. I've renewed and gapped my spark plugs and gave it a service aswell. The only other logical thing i can think of is sensors, wether it be the map, icv or coolant temp sensor. Anybody else had a problem similar to this? Im thinking about sticking it on the peugeot planet diag machine in work tomorrow if i get a chance.
   
   Cheers, Kriss

   hi, this happens to me aswell, its definitely not the starter motor as the engine would not turn over. its a sensor of some kind.
   
   i have tested and cleaned my temp sensor, sensor was ok, the fault still persists so im thinking its MAP sensor or ICV

   I would bet on that downpipe gasket leaking being the cause of the problem. Mine did this when i had a leak on my manifold. I gave it to my dad (mechanic) he sealed it all up with a new gasket and all was fine. Apparently it's due to lack of back pressure generated when running the car. As soon as you try and start again it will take a few cycles through of fuel and everything has expanded around the gasket sometimes causing more of a leak therefore a big lack of b pressure. The exhaust plays a big part on how the engine runs in general so i would make that a priority to get sorted mate.

   Mines done this a couple of times i`e replaced the coil pack at the moment it seems fine,the other thing to look at is a possible air lock in the fuel system.Modern spark plugs (the majority)anyway come pre-gapped & don`t need gapping.Check your fuel filter as well it might be blocked & run some fuel cleaner through your tank.

   Problems still happening, however it does it randomly wether the engine is warm or cold. Cleaned out the icv, fitted a new starter motor and changed the map sensor. It has made fuck all difference. Starting to run out of idea's.
