starting problem issue is diferent at cold or hot engine start, when it hard to start cold engine you must check fuel pressure before starting the engine , if it is not sufficient your problem is in fuel pressure check valve at fuel pumps($30 each) , if the starting problem is at hot engine your problem is damper($180) , that is the cone type aluminium piece next to pumps. if you have one of this problems - it is real meaning that your fuel pumps are weak and need help , first remedy to it will be ATF to the tank to lubricate them.
irregular idling will be a different problem, but you can not jump to that before fixing fueling problem.
good luck
