stalled now wont start

Just replaced the fuel pump and e.c. mod on a 89 ranger. ran fine drove it 2 days then just stalled. Tried to start but just wont turn over. :banghead: just got the truck running after 3 weeks of being off the road. now what, im banging my head against the wall trying to figure this thing out. where do we look next. any ideas?????

check for power to starter and go backwards to starter selonoid, battery cables, Battery. could be ignition switch. Is it in park. Or safety switch on clutch could be bad. start by getting power to the Starter

the truck is a 89 with a 2.9 , 5 speed. theres no power going to the fuel pump, so we replaced it again, under warrenty still. still the same. checked all the wiring and it seems fine. looked at the new mod , seems fine. now we're scratching our heads on what to do next. was running fine til it stalled. just tested the wiring for the fuel pump and its not getting enough power, tracking it down now and we also tested the battery and its fully charged. plus we replaced the ignition coil.
