Hi

From my (limited) experience (hehe),

Cold hardstart - faulty cold start valve
Warm hardstart - faulty fuel accumulator or fuel pump check valve (suspected especially if fuel pump has not been recently renewed)

When you say that it floods out like there is too much gas, how did you arrive at this conclusion? Bad fuel mileage, black smoke, severe hesistation at low revs, etc?

You have changed all the items (esp the BIG TICKET part - fuel distributor) that could POSSIBLY contribute to your car running rich (if it is indeed the case).I have worked on 190Es which ran rich and some required swapping out either the fuel dist, fuel reulator or fuel injectors - you have done them all.

Please provide more details and I'll try to help you out as much as I can.

My 190E had the same problem last year (it was discussed in a long thread on this site as well as 190revolution.net - see "babybenz") and I solved it by swapping out the fuel distributor which I got from the wreckers at $500 or USD280 (great deal!).

Cheers.
