Jeep Repair: hard start 93 jeep gc, dealer ship, coil car

Question
I have a 93 jeep gc with 4.0 liter strarting having problems about a month ago it craks for about 10-12 times then starts up we did a full tune up plugs, coil, car and rotor fuel filter, air filter. started ok for a day someone said collant sensor so i repleced it no difference noticed pressure reg. was leaking into vacum line replaced it ran ok for two days, got tired of messing with it so I took it to the dealer ship. the did a full diasnstic and was quik to say fuel pump so I had that replaced the whole modual 700 bucks . it started fine tfor two days and now takes 10-12 cranks to start. after it starts it idles fine and has plenty of power it never had any problems while running just gettiting it to start. the dealer shio says they cant find anything wrong but it never started like ths before. I just want to start right winters coming and I dont need this problem at 20below. one thing to maybe factor in is that the temps up here have been 80 one day 50 the next. hope someone can help

Answer
Well it could be a problem with your ignition modual or it could be your starter.  The ignition modual could cause that or the starter can have a problem.  Sometimes starters have a problem with the rods inside of them and that is when they need to be changed.  If that isnt the problem then bring it to the dealer and get a new jeep.
