I am now an "expert" on this problem. Even John Delorean would call 
me if he had the problem as he should also understand that I am the 
worlds formost "expert."

I had the exact same problem and I replaced vitually every component 
in the car at DMC in Garden Grove! The bills were staggering! The 
car would not hold presure after a shut down, and this is important 
for it to do so as to not vapor lock on a restart when hot. 

First it was the fuel injectors. After $187 in parts and $140 in 
labor it still did the exact same thing. It would start when it was 
cold and not when it was hot. 

We then "replaced" the check valve because the system would still not 
hold pressure. After a $69 check valve was installed and $285 
dollars of additional diagnostic labor it still did the exact same 
thing!

Next we replaced the fuel accumulator which I had replaced 11 months 
and 800 miles ago. After $109 and another $140 dollars of diagnostic 
labor it still did the exact same thing.

Next we replaced the "o" rings in the fuel distributor and after 
several hundred more dollars of labor and parts, it still did the 
exact same thing!

Next we put a clamp on the supply side of the fuel line at the 
distributor and it still lost pressure. The we put a clamp on the 
return line from the distributor and it held presuure.

Somehow, we determined, after some additional labor, that it was the 
fuel distributor that was "defective." This was after we invested 
some more labor costs to see if the fuel pump was defective.

We changed the fuel distributor and for some reason, which I do not 
understand, it now runs fine. It starts both hot and cold, it runs 
smoother, (the surging that used to exist on cold starts has improved)
and I am ready to declare personal bankruptcy.

On the serious side of things, try the fuel distributor as all of 
the "experts" will tell you that they never go bad and apparently, 
they do. In the meantime, pray that it is the accumulator as it is 
1/10th the cost of the fuel distributor. I am now an expert and 
hopefully, you are too and, maybe, I'll be able to save you some of 
the expense that I incurred in the learning process.
