More Info On My 380sec Fuel Problems

Hi members . I will be more explicit .My merc 380 has been running perfectly until 2 months ago(a hot day) after leaving it for 1 hour it would not start for about 10mins then it was fine.This happenned again a few times but only on hot days (rest of time its fine).Then on wed last week (very hot day) after using her for an hour or so she would not start .then after15mins she goes and I drive normally back to my home but on way home she starts to splutter and seems to tick over ok but when I give gas she just won't pick up?Its very odd but if I turn ignition off then on again and squirt the gas pedal then turn engine over then she is ok for a few miles .However after few miles the splutterring returns.Anyway I get the car back home (nursing it) and low and behold the next day she starts fine and will be ok unless its a hot day and then It will all happen again??? something is breaking down and stopping a smooth fuel flow?I would be grateful for any help members as I'm at the end of my tether and ready to give the car to my merc mechanic.The expensive option which I can ill afford at present.
Kind regards Chris

This is fuel related could be one of the pumps if you have two.

If you have two, take the wire off one and see if it starts, then do the same with the other one, then you will know if you have a faulty pump

They are just behind the off side rear wheel behind a plastic cover.


If the pumps run slow, take them off fill them with diesel and run them backwards. this cleans out any crud and rubbish

reply to star.

Hi star. No fuel pump is very quiet indeed. Please can you tell me what the divi cap is? Where is the divi cap? Sorry but don't even have a manual for my 380sec and really not that technical .Wish I could get a decent workshop manual for my car? Haynes don't cover this model?? Do they?
many thanks Star. Chris
