1993 ford explorer shut off will not restart

tested all fuses and relays all are fine also my check engine light dosent come on at all

ok,if you tested all the fuses and relays with the key on,both sides of each fuse and test shows they are "fine",why did you replace the fuel pump if there was NO power at the inertia switch? if no power at inertia switch,then there will no power at the fuel pump either(is it tripped)! you will only see power coming in and going out for a split second while a helper turns the key to on and you can not check the MAF sensor unless the vehicle is running for it's performance/readings by back probing it without unplugging it. the check engine light should only come on when the key is turned to on for a bulb check and will go off and not come back on unless you have a code stored after the engine is running.

i am 70 and think old school . never thought about power. i thank you for your input.

10-4 on 70 years young,and I'm not far behind you! I sure don't know anywhere near everything there is to know about vehicles,but I do work on em. Now I do have an F150 a little newer than yours and I have owned a few more around your year model and had very little to no problems out of any of them and would still have the first one if that rollback would not have ran into me and caved the whole drivers side in? Now,pushrod is in here on your question also and he has been working on everything(all makes/models) for over 45 years and he knows a thing or 2,cause he's seen a thing or 2! I'm sure he can/will give you some details about where to start and what/how to check.good luck to you....

thank you. i had a 93 f150 that did this same thing . i ended up selling it because no one could find the problem. the guy i sold it too told me latter he ended up replacing the wireing harness . i dont know if thats true. ithink i may just end up towing to a shop ,idont know . i sure hope some one can help shops are so expensive.back when i had the f150 all this great help on line wasnt around. anyway thanks.
