[W126 Coupe] Clay's Last Shot

[Mister McGoo]

Clay;
 
Try unplugging the power to the cold-start injector. (The blue electrical connection directly behind the distributor).  Could be the cold-start injector is not shutting off (defective sensor). 
 
If no change, see if you can find a known good (or new) cold start injector assembly to try. Could be the cold start injector itself is defective and is pouring fuel into the intake all the time.
 
Don't quit posting questions.  You're not bothering anybody.  This is what the site is for, right?  This is the site where people pool their collective experiences, and eventually some contributor will hit on an answer to your problem.  The more symptoms described, the better the chances of finding a solution, and every solved problem can be more knowledge for everyone.

Well Guys,
This will be the last time I write about my problem, so not to take up space. The car almost wants to start on 1st. turn of strater, but dosen't and you have to hold pedal to floor and then it starts right away. Played with fuel dist. counter clock wise leans it out, but it idles up and down between 750 and 900 but still running rich. Black smoke at idle and alittle at higher rpm 2000-3000. It's like its getting too much fuel. Runs on highway ok, but still have battery draw when tested with neg. off to a ground on car. What would make it run so rich and cause the draw ?
Only after having fuel filter changed ? I forgot you can smell the gas also, but can't see any leaks by engine or fuel pumps.  I know to many questions.
Someone give me some help.
Clay Moizo
