Warm start issues

[fredbloke]

I have an m52 e30. I am currently having warm start issues just turns over and stutters a bit but can take ages to finally start.
Starts forst time from cold tho.

Any ideas
Cheers

Engine temp senor faulty maybe, could be telling the ecu it's cold when the engine is warmed up, to much fuel going in, still in cold start mode.

Similar issues here, diagnosed to the fuel pump. Lift rear seat squab, remove cover over pump and tap top of pump whilst cranking over. Temp fix until replacement (not cheap)!
