there is a full tank of gas.
the oil pressure is suddenly only 5 psi. it has been reading 50 psi every day this past month, so I am looking at the sending unit.
I read the entire service manual AGAIN, and there is in fact an oil pressure shut off. so with this low of oil pressure reading, it will not start as a preventative measure.

I will replace the oil pressure sending unit. Apparently these fail a whole lot in the older fords, and it seems like a pretty easy swap out.

I will try the gas in the carb though and let you all know what happens.

Oh, and more interesting.... the ignition wiring harness is directly next to the volt regulator I had replaced the other day... so, I will check this too...

For short term I would not be afraid to by pass low oil pressure switch but long term it is nice to have working for obvious reasons.. You will get her her going. Let us know when she starts.

Instead of using gas I use to spray wd40 in the carb

Two things:
1. When you have the air cleaner off, try moving the linkage to actuate the choke. IF the choke does stick, put the wing nut on the threaded hold down rod down about 1/2" . Then give the end of the rod a few light whacks until the choke snaps open. Remove the wing not, install the air cleaner and reinstall the wing nut, just enough to not be able to rock/rattle the housing.

2. Pierce hit the nail on the head when he said don't have a container of gas in your hand after pouring a teaspoon in the carb.
{Here is what some dumbass did (no name here please) while trying to get his 1932 Model B sedan Ford with a Wiend Drag star six carb intake manifold on a beefed up Cadillac V8 started on a rainy early spring day. No gas tank because I had boxed the rear frame where the tank used to mount. Trying to sell the rod and needed to start it for potential buyer. Took a soup can 3/4 full of gas and poured some gas in one of the carbs while cranking the engine. BOOM!! BACKFIRE!!! Engine started to die so I poured some more gas in . Backfired while gas was going in. Dumbass panicked and threw flaming soup can of gas on the vinyl roof of potential buyer's BRAND NEW (sticker still in the side window) 1967 Chevell SS. Then I ran over and , because my hair above the collar was on fire, dove into this little bank of snow and tried to swim the fire out. Long story short: car got sold to the guy, I was missing eyebrows, eyelashes, and had short, short hair on my head and forearms until everything grew back. And I smelled like burnt hair for a week!

Nitehawk,

I cleaned a rusty go kart gas tank with acid but could not see if it was completely clean so while I was looking in the tank, I lit a match. I remember the flame just before it hit my face and burned my eyebrows and hair off. This was in high school. Perhaps this is why I became a fire fighter.

Firewhirrl, keep us in the loop.

Firewhirrrl, Yes your problem is with the oil sending unit under the air cleaner, after chasing this on my 87 460 carb, for close to 2yr, 3 shops, and 2 tows.
A 3 inch piece of wire and 2 quick wire connectors are needed, tap in to the wire at the oil sending unit about 3-4" from where it attaches to the unit, "think its a brown wire" make a U In the jumper wire and attach to the other brown wire running along side of the oil sending unit, this wire goes to the fuel pump and attach wire there, this will bypass the shutdown safety system and will let you start and drive your MH. Do let it warm up though! Good luck, done mine on the side of the road in 15mins

Does the '87 OREG have conventional hydraulic brakes? Disc or drum? How does the parking brake work? Just curious...

Yes the 87 OREG has conventional hydraulic brakes, with a master cyl. That also is ran off the power steering unit with a Hydro-boost unit, 4 wheel disc brakes, the parking brake has a brake drum at the end of the transmission/driveshaft, also Ran off the power steering unit, still takes dot 3 brake fluid in the master cylinder

Power steering pump runs the power steering, Hydro-boost brakes system and the parking brakes.
The reservoir holds about 4 qts. Of type F transmission fluid

There will be no oil pressure if the engine is not running -- there will be an oil level.
If the starter turns the engine over, the engine needs fuel and spark to start.
Running out of fuel is not advised in a large vehicle like a motorhome, especially in areas with steep hills.

After reading this thread from the beginning....... I was wondering why no one made this point until now?

Ive' never heard of an older engine that required "oil pressure" to start, but will shut down after a time delay if running.
