B12 HARD START ON MORNING

[b14inb12]

have a B12 fuel injected original. on mornings i will get a hard start will have to tumble three or four time to get it going and when it do start it will tremble a bit.if i park for about two hours the same thing will happen, had it check out.
the mechanic change the fuel regulator,fuel filter and the fuel pump. still the same problem.
i have doubts about the fuel pumps.
why,
cause its a b12 injected and the pump are hard to come by. but he said he change it.
i need to know is it the fuel pump or some thing else

i am not getting any black smoke when i start the car. it a hard start on mornings and two hours after a hard start again its like it have no gas up front to start the car,once i start the it will start good after. if i stop for two hours it will give me the same problem.no cutting off in traffic only a low idle once in drive.

padna coolant temp sensor have nothing to do with black smoke. and if it malfunction the car wont idle up cause the ecu does know that the car is cold and wont activate the step up.
