Do you have spark and fuel pressure? Check the inertia switch? You might try a spray of starting fluid. If it tries to start you would know that the engine has spark, but the injectors could be working without fuel pressure and starting fluid would show you it is a fuel pressure problem if the engine fires with starting fluid.
There are a few things you may try. Assume the opposite for fuel flooding and hit it with a sniff of starting fluid. If it tries to do something then you need to check why fuel is not getting to engine. You can use a multi-meter or borrow a noid tester to see if injectors are working.
As this is a motor home it can surely be wired different from a standard F350. There is an inertia sensor in Ford trucks to disconnect the fuel pump on impact. The inertia switch has a simple reset button on it.
As you have an older vehicle, the multi-port injection style has a crankshaft sensor which also sets fuel PSI. Can't say about yours, I know that there were throttle body injectors in 1984 Ford cars, but truck gross weight exclusions for EPA stuff even had carburetors remaining on trucks years later.
Your tester for problems needs to be for the earlier electronic ignitions. Its hard to do ECU testing without proper tools. One thing you might look at is the temperature sensor. The cold start sequence is triggered by the water temperature sensor telling the engine that it is cold and needs to enrich fuel mix through the ECU. It makes starting easier.
engine wont start ??? yes you can try start fluid , but etreeme care needs to be taken using this on diesels as the fluid can act as a fuel (of course it can!!) and the engine can run away till its fluid supply burns off (too late!) use it in small doses !! me I use kerosene or my fav is paint thinner ,its a bunch safer and wont destroy the engine like st fluid can , if it sputters on st fluid and still wont stay running , then you have an injector/pump/supply problem , if it wont do anything at all when u crank it over then you have a pistion/valve/head problem
Check for spark to the sparkplug. Try a shot of starting fluid as having gas pumping and having the fuel injectors opening are 2 different things. If you have spark, then the fuel injectors may not be working. Quick diagnosis is to use starting fluid and see if engine tries to run. This indicates problem is not lack of spark but lack of fuel getting into cylinders.
What have you checked so far ? Is it getting spark to the plugs ? Can you spray starting fluid into the throttle body and get it to start ? Have you checked fuel pressure at the injectors ?
A fuel filter will not cause a no start, check the pressure and see if you have any. Spray starting fluid into the intake and see if it starts and stalls, that indicated no fuel pressure. Also run a MECS OBD1 computer control system fault code test, you will need a MECS (Mazda Electronic control system) system scanner to do that or a Ford Star tester with a MECS adapter kit. (Ford owned a controlling interest Mazda then and now) You may just have a failed fuel pump.
After repeated checks I found a faulty temperature censor which allows current to flow to the high idle solenoid and fuel preasure solenoid. It fired up rather quickly and didn't need any starting fluid.

ok moisture can cause problems with gas and spark. try some dri gas or something first, check the fuel filter. or somekind of timing with the injectors and the ignition switch.
