Phil,

Went through the same gyrations with my 90 200TQ. Per all the treads sent in
the most likely culprits are the check valve and the injectors. 

Had the same extended cranking when warm. VERY extended! Replaced the check
valve at the pump. That corrected the problem, shortly thereafter started
having a similar, but not as bad, problem with injector leakdown. As of
present the car (after shutdown) will bleed off some pressure through one
(or more) of the injectors. Cranks for several seconds than fires and runs
rough for a moment. Car emits a slight amount of smoke then clears up.(rich
condition from leakdown) 

At some point I have to pull the head to fix the two broken exhaust studs,
will do the injectors then....

Anyway, based on my experience I would suspect the check valve. Inexpensive
part, just a hassle to replace. Run the car until it's about out of fuel
(BTDT, PITA to do with a full tank) and pull the pump. Shouldn't take much
more than a hour to replace.

Eric
