ok under the hood in the power distribution box there is 30 maxi fuse that runs everything your describing isn;t working the fuse is in spot u the most likely cause if it is blown is the fuel heater try unplugging the red and green wire off of side of fuel filter housing if fuse is not blown then i am out of ideas i will keep looking over wiring diagrams to see if i can come op with something hope this helps sorry i am not doing much better but i will not give up yet

Expert:  Nathan Hosier replied 4 years ago.
ok
Customer: replied 4 years ago.
NATHAN,
I DID WHAT YOU TOLD ME TO AND IT STILL WON'T CRANK.I PULLED THE GREEN AND RED WIRE OFF THE FILTER, TURNED THE SWITCH ON AND I HAVE NO POWER TO IT AND IT STILL WON'T CRANK AND THE WAIT TO START LIGHT WON'T COME ON. DOES THE WAIT TO START LIGHT RUN THROUGH THE MAIN COMPUTER OR THE IDM? I'M AT WIT'S END, I'VE TRIED EVERYTHING YOU AND I CAN THINK OF. ANY MORE SUGGESTIONS?
Expert:  Nathan Hosier replied 4 years ago.
was the fuses unde hood ok
Customer: replied 4 years ago.
I HAVE NO FUSES UNDER THE HOOD. ONLY FUSES I HAVE ARE IN THE CAB BY THE BRAKE PEDAL. ALL THOSE FUSES IN THE BOX ARE GOOD INCLUDING FUSE 18. THERE IS ONE MORE FUSE OUTSIDE BEHIND THE LEFT HEADLIGHT AND IT CHECKED GOOD.
Expert:  Nathan Hosier replied 4 years ago.
i am not understanding are you saying there is only one fuse under hood there should be several fuses in a power distribution box on Lh side probably by brake booster that contain pcm relay idm relay and fuses that run all the eng controls just checking to make sure we are on the same page
Expert:  Nathan Hosier replied 4 years ago.
the fuse under the hood should be labeled on the lid as the positon u check to see if you have 12v accross both terminals if you dont then go under steering column there is a red and green wire coming out of ign switch turn key on and check to see that there is 12v coming out of the wire in run position and start position if there is not then the ign switch is bad if you do have power there but no power to fuse then you have a open wire between the ign switch and power distribution box check the connector c212 Lh side of eng compartment big connector 76 pins hope this helps
Customer: replied 4 years ago.
MY VAN DOESN'T HAVE A POWER BOX UNDER THE HOOD. IT HAS AN IDM COMPUTER BOX IN THE LEFT FENDER BEHIND THE BATTERY AND A MAIN COMPUTER TO THE RIGHT SIDE OF BRAKE MASTER CYLINDER. MY VAN IS A 1995 E350 DIESEL 7.3.
Customer: replied 4 years ago.
NATHAN,
I WILL TRY WHAT YOU SAID TOMORROW AND GET BACK TO YOU TOMORROW.I HAVE HAD IT TODAY.
THANKS,Customer
Expert:  Nathan Hosier replied 4 years ago.
according to my ford wiring diagrams your supposed to have power distribution box by the brake master cyl if it possible take a picture of your van on the left hand side and email it to me at hhracing524@hotmail.com so i can see what we are dealing with i think maybe it there i think it is just below master cyl down a ways hard to see if you cant do that maybe you should take to dealer because my diagrams that i have are starting there if not you still can check the red and green wire coming out of ign switch also try to trace wiring from where it comes through fire wall from ign switch through that big connector cause they will end up at the box that i am talking about
