Hard starting cold/hot/poor gas mileage
I own an 86 560 SEC with 150,000 miles. Starts in one turn cold, 2 turns hot. My 87 560 SL is hard starting cold or hot, and runs lean on three cylinders (compression is fine). Same engine in both cars. After spending well over $ 1,000 on the SL, I'm about to change out the fuel distributor to try to correct the lean condition in three cylinders (poor mileage probably caused by mixture compensation). Based on the threads I've been reading regarding cold/hot starting problems, should I also consider changing:
1. Fuel accumulator ? 2. Vacuum modulator ? As a former mechanic, I hate taking a "shotgun" approach to a problem, but the lack of diagnostic capability on cars of this vintage leave me little choice.

Sandler 1986 560SEC: 150,000 miles, runs great, but I've got to sell it (too many cars for one man) 1987 560SL: 122,000 miles, used to run poorly, now (thanks to forum), runs great! 1997 GMC Jimmy: Turned out to be a turkey. 1989 T-Bird Super Coupe: 150,000 miles, still runs great. Ford got it right.
