Engine problem 930 78 3,3

Hello. When engine is hot and has been off for approx. 45 minutes. Start it badly. it is as though drowning. First I thought it was fuel shortages and changed a whole lot of parts it did not help but think now that it drowns. What can I do about the problem ???

Regards john

Assume you are running the stock CIS? Hot start issues seem to usually be traceable to a bad fuel accumulator or check-valve at the front fuel pump. You say that you've replaced a lot of parts already...was the accumulator one of them?

Have you verified your hot/cold control pressures, operating system pressure and residual pressure? I'd check these things first. When you say its "drowning" I take that to mean you think its rich (too much fuel?). Maybe there is an issue with the cold start valve.

Had same problem on my 78 930 last year.

I replaced fuel accumulator and have never had this problem since
