Can anyone help?
Car starts perfectly from cold. But warm start is a struggle ~ doesn't quite want to fire sometimes. Also, the fuel pump/s seem to be struggling and humming more than usual?
Clogged oil filter? Knackered pump? Dirty injectors?
Any thoughts appreciated.
Thanks

 

Check your leakdown fuel pressures. If they fail your fuel accumulator is bad.

So embarassing when you cannot restart - and the looks you get from curious, yet usually smirking onlookers!
Sounds like I have a failed high pressure return valve on my fuel pump(s). Cold start enrichment system compensates on initial start up, but is of course inoperative once the engine is warm, hence no fuel.
