I am new to the forum and was just gifted an 04 fx35, with 97k miles, that is in texas (i am in washington state) the car is having the typical starting issue where it cranks but wont fire up. from what i understand the car had hail damage but was repaired and apparently did get some water inside. because of this i plan on replacing the a/c amplifier(this sounds like a common issue), the bcm(door locks and trunk dont work but seats and other electronics do) and the ecm as these seem to be the culprits when reading through other threads.
i also plan on replacing the crank sensor, cam sensor, and spark plugs. can any one think of any other electronics that should be replaced or be the culprit? i want to get all my ducks in a row before i fly to texas to fix it as i dont wanted to get stranded on a 2000 mile road trip home.
now for the second part of my post:
when i search on ebay for the ecm and bcm i see alot that say "for 03,04,05,06" with no part number, but when i did a little more research it looks like each year has its own part number. i called a local infiniti parts department and they told me that both the ecm and bcm are year specific. i was told i need the ecm part no. 23710-cg700. my fx is rwd without active cruise control so i know i would need one specific to that but has anyone tried using an ecu or bcm from a different year?
ican get the part through infinit but its about $200 dollars more than on ebay and i would rather not spend $350 if the part dosnt even need to be replaced but i am prepared to bite the bullet if need be.
any advice would be most helpful.
