warm start up problem
 

Anyone have diagnostic steps and or tricks to solve a warm start problem on a 77 911s?

Many thanks

residual pressure check. but you still need to verify FA or check valve.

remove the return line from the accumulator. if fuel comes out, the FA is leaking.

if not, replalce the check valve at the fuel pump, or just do that anyway.

Thanks for the advice, ill give them a try. I have worked on a lot of 996 and newer Porsche's but i have little knowledge and training from my Porsche turbo track classes i took almost 8yrs ago while working for a dealership. In all i got a good deal on this car and luckily so far this is the only problem i have come across.
