Check/ replace: fuel filter, fuel pump pressure, timing belt timing.
i had the exact same problem and i also replaced the switch and relay. the problem was in the wiring right at the positive post on the battery. also had to clean up many of the fuse links as well.
Need to know what size engine you have in order to answer your starter problem. 1993 Nissan pickup with v-6
yes
no
no
most likely it is a fuse
no
sounds like a temperature sensor problem
blown fuse or blown fusible link.
I had this problem on an older (1987) Nissan pickup and it had two injectors one of which had gone bad- replaced it and it fixed the problem. If I remember correctly it was designed to use one injector up to a certain speed and then the other was made to kick in for higher speeds. This may be your problem if you have a 4 cyclinder- if you have a V-6, I don't know.
no 84 and 85 swap out.
no sir ,87 and 88 change out.
