96 zj

[dan]

i recently inheirited a very clean zj that has the 4.0 it has also been sitting for a year and a half, my uncle was driving it down 75 and it just shut off, he replaced almost every sensor there is and took it to a shady mechinc but had no luck with getting it going ( the garage should not be allowed to touch a car) my uncle died recently and my aunt decided to give me the jeep so what im trying to figure out is whats wrong with it it has spark has fuel and the timing is good so any input would be very appercated
