hey! I have a 1987 trooper II, 2.3L, 5 speed manual. I had some issues with it awhile ago about just dieing, but now it won’t even start. It will crank over (if you use gas or either in the cab, it starts for a second until it’s used) but it won’t start. I was woundering what would be some good ways to trouble shoot? I already tryed my relays and even checked to see if I had an inertia switch on it ( IT DOSE NOT). My filter is a little black and I’m get that tommrow but if that dose not work, what should I test before just dropping my tank?
