Thanks for the diagram and the quick reply.

 

When I can get back to work on mine, I will share what the problem turned out to be in the hopes that it will be of some use to the community.

hey holaman , i have that same old looking old starter relay on my 84 460 E-350 except mine is a RV. Mine is located on drivers side above my second battery. It is ties into my second battery. The battery on my drivers side runs the lights for the RV. Did you ever find out what that old bullet proof relay is for. Im thinking it has something to do with charging the second battery.
Thanks Chris

 

Sorry I didn't get back to you right away. I didn't know about your post because I don't get on the computer everyday.

Mine doesn't have a second battery nor does it have provisions for a second battery so I don't think it has anything to do with dual battery set-ups. I'll be getting back to work on this real soon so I hope I'll be updating soon. I'm also thinking that I may have been too quick to dismiss the oil pressure switch as a possible cause so I'm gonna be taking another harder look at that as well.

Regards,
Eric

 

The reason why I never updated this thread as to the cause of my trouble is because I just gave up on Uncle3. I am however moving now so this rig HAS to run now. So here we go. We are finally going to figure this out, even if it kills us!

The very first thing I suspected when this trouble first began was that device that kills the fuel pressure if and when the vehicle is in an accident. Where is this thing located? Is it part of the relay? Is it nearby? What does it look like? How can I temporarily bypass it so that I can properly diagnose the cause of my lack of electrical power to my fuel pump?

 

was stripping down an 89 E350 cutaway today, and the fuel pump reset switch is on the R kickpanel , saw it when I was removing the ECU and harness.
460 EFI with a C6........... thought it was a little strange but the rear axle has 3.55s so that's all good.





hopefully gone by thurs. in slightly different condition

 

Thanks for your post. I can't find any trace of it in that location. Maybe it's because mine is an 87, the last of the carb equipped models. That's why I don't have an ECU behind that kick panel either.

 

it will be inside the cabin somewhere. is your wiring diagram an 87 model?
ECU on this 89 is under the heater box. little plastic cover on it , not behind kick panel. I can go take a pic of it if you like , might take me a while to load it onto photobucket. PM me and I can email the pic direct if you like.

 

That diagram was posted by subford so I'm not sure what year it's for but since he posted it for me I'm thinking it's 86ish-87ish.

Could you please just post the pictures here in this thread? (So that all can share in this knowledge.) A close up of the inertia shutoff thingy itself and then a farther away shot showing it's surroundings for a reference point? Thanks for your help!

 

can't get my flash to work , will have to take some in daytime lighting.


will have to get some on Wed. can see this switch without removing any parts really, but this is a barebones model, not even AC. your MH version may have some cover panels installed by the builder...........


will take some pics in the daylight, I would think your switch is same as the EFI vehicle of that year as there were lots in the Fseries and automotive applications. and yours was a model in transition

 

Mine is a non-A/C stripper box truck like yours. You may be confusing me with the OP. I kinda hijacked this thread instead of starting a new one so that we wouldn't end up re-exploring stuff that was already covered here. I figured it was better to just pick-up where this thread left off. No "do a search, this has already been covered" posts that way. It's a very fine line we walk, between starting un-needed new threads or hijacking and/or reviving other tired old threads. The difficult choices we have to make in life!

 

Correction: subford posted that diagram in response to cjcipro's inquiry, not mine, so that may be for a 84ish period piece, because cjcipro's rig is an 84.

 

Someone posted once the fuel shut off switch (Inertia switch) on a 460 cutaway carb in ~86 or 87 was in the engine compartment mounted on the fire wall drivers side. They did post a photo but it was a while back.

The 1995 E&VTS manual just says it is located "Under the I/P".
Some had it mounted on the safety wall near the parking brake pedal.

Subford!!! It's been a while!

Thanks for your post. I'll check that area and get back to you guys later. Have to put in some work hours first.

 

well mine is located soemwhere completely different and has a 1987 part number so........................





it is mounted above the kick panel on the right side, right beside the heater box.
