Car is very difficult to start first start of say, then is ok all day?

my 1991 lesabre 3.8l . has new wires, plugs, battery, alt., engine light on, codes as crankshaft pos sensor. Has been replaced, light still on. Very hard to start. Takes about 10 minutes, til battery almost dead. It sounds like a couple cylinders fire, but won't catch. Fuel pressure at 45, no leaks, no apparent vaccuum leaks. I have to pump accelerator to get it to start chugging, seems like only a couple cylinders fire. Believe me, runs and starts great all day after initial start. Plenty of power, no hesitation. Occionaly will stall when stopping at lights, once in a great while. Occionaly cruise control will fail after being set, speed goes down gradually. But will work again with resetting. Mileage good. Please help. Thank you all.
