88 Ford Bronco Ii Will Not Start

My Bronco II 2.9 4X4 WILL NOT START. ABOUT 6 MONTHS AGO I HAD SOMEONE DO A TUNEUP ON MY BRONCO. IT RAN FINE FOR ABOUT 5 MINUTES. WHEN I BOUGHT THE BRONCO THE PREVIOUS OWNER HAD REWIRED IT SO THAT IT RAN FROM THE PUMP IN THE TANK. IT BYPASSED THE RELAY AND THE PUMP ON THE RAIL.AND THEY REMOVED THE INERTIA SWITCH. THE WIRE COMING FROM THE PUMP IN THE TANK HAS A FUSE IN IT. WHEN THE PERSON DID THE TUNE UP THEY DECEIDED TO "FIX" THE WIRING TO THE PUMPS. NOW IT WILL ONLY START WITH STARTING FLUID AND ONLY FOR A SECOND. THE PUMP IN THE TANK IS ONLY 1 1/2 YEARS OLD AND WAS BRAND NEW WHEN PUT IN. PLEASE SOMEONE GIVE ME SOME SUGGESTIONS ON HOW TO FIX. THANKS

Not sure If you have fixed you problem yet or not. I would have the person that did the tune up un-fix the wireing to the tank. Reinstall relay and fuse. They were there for a reason seem so!
