89 200q No start....

[Allen Swett]

Hi listers,
My 89 200q refused to start today at noon, after sitting for 10
minutes....cranking, no response....Will check out codes this evening after
work, but would appreciate any insight, if this situation sounds familiar.

Car is fully in spec as far as tuneup 12k ago, running full boost, with no
problems until this...
Lately upon starting it, over the last couple days it's taken 3 times as
long to turn over, and when it did, it would run as if it was loaded up or
flooded, then usually clear right up....
Last night it did seem to run a little rougher than usual, not much, but
noticeble.  
After replacing the injectors in the spring, the car has always started
immediately, first crank....so I'm stumped....Mileage has been down a bit,
I've attributed it to the 4 snows I recently remounted, around town I'm
averaging 19-21mpg..

I realize there is not much to go on, but if anyone has any insight It'd be
much appreciated...will be checking codes and going from there this
evening....

Thanks!
