Question about Ford F 450 Super Duty

1 Answer

Ford based RV - 460 cc - possible fuel issues?

I have a 2000 Lazy Daze RV with a Ford 460 cc. Low milage 41k. On a recent trip we drove for 3 hours on the freeway. I stopped to get a parking pass and turn the engine off. Went to restart it a minute later and it would not start. Battery voltage looked good, tried again after letting it sit for a minute. It finally started on the third try. This was a couple of days ago. I thought it might have something to do with the engine being hot. Next few days no problems RV runs and starts fine. Then this morning we go to leave another camp site and batteries indicate good. It cranks but no start. Then after a few minutes it starts up on the third try. Any thoughts - fuel filter, fuel pump. Anything I can check or if I do take it to a mechanic will they have a way to diagnose it so I don't just throw money at different possibilities? Thanks. Justin

I'm not familiar with the vehicle (I write from the UK..) but yes sir, I would agree with you that it does sound like hot engine/fuel issues. Or maybe a 'cold start' injector, assuming it is a petrol engine.

I also agree that you don't throw money at it.

Personally, I would change the fuel filter (and air filter) anyway, it's the easiest and cheapest option.

You don't mention any problems when the vehicle is running, so I presume that when it is actually travelling, all is fine? If you had intermittent problems with the fuel pump I would have imagined that your vehicle would stall and splutter from time to time. Plus, at the low mileage you have done - a fuel pump shouldn't be failing or have problems.

I would change the fuel filter (and air filter if necessary) and also pour a can of 'injector cleaner' into the fuel tank as a 'lazy' or gummed-up injector(s) can cause starting problems - and take the vehicle for a nice fast run to 'try and clear things'.

Do the simple things first. The things YOU can do. With low mileage vehicles a 'glaze' can build up in the fuel system simply because the vehicle is low mileage /short runs. This causes injectors to become 'clogged and sticky'. Run it with additives in the fuel system ...

If all else fails, ask a workshop. But .. it sounds as though your vehicle is reliable apart from the starting-niggle. I don't think you have a big problem.

SOURCE: car won't start

Your fuel pump is sticking and not pumping, this is common if you run the fuel down to less than 1/4 full, the fuel pump needs the gas to cool itself, below a 1/4 tank the pump is not getting cooled and after repeatably running low on fuel it overheats and fails. Running the car near 1/2 tank extends the pump life to many years more than running tank below a 1/4 full..

SOURCE: 1999 Cadillac Catera - 103,000 miles - cranks but no fire

Hello carol...from the symptons you describe more than likely it's the CPS (crankshaft position sensor.)
The CPS is a common problem on Cateras with these symptoms.
The sensor is a magnetic impulse type that sends a signal to the computer, the computer then triggers the fire signal. When the CPS gets weak, dirty or has low voltage the intermitten no starts occur. It will finally result in a no start at all...Please be aware that a lot of caddy dealers will and have overcharged customers for this common problem by ill advise and replaceing uneeded componets.
Good luck...i hope this helps and will fixya up.

SOURCE: 05 ford escape wont start. jump started it and it

okay try this....talk to your parts store and get a battery load tester, and find out if the battery is indeed dead. My guess is it sounds like the Altenator is dying. they are around 50-100 and can be install by a pro in minutes.

I think you should check your battery and alternator.If they both check good you may have a battery draw,something draining the battery over night.Check your doors make sure they are closing like they should.

So, if when it happens you don't hear anything, perhaps it is your safety interlock switch acting up. Have you tried starting in neutral (assuming you have auto transmission)?

Please see my tip at http://www.fixya.com/cars/r6222268-engine_doesnt_crank_turn_over . These are generic instructions. If you get stuck or need specific instructions for your car, please get back to me with model, year and engine info.

Yeah I got a 1985 e-350 Ford based ,21, ft RV with the 460 cu engine what kind of mpg should I get with this unit. It is carbureted and has a 411 gear ratio in rear end


probably around the 15 mpg mark if you have good driving habits and the vehicle is not too much overloaded or speeding
fuel economy is always in the driving habits and is always guess work
if a torque cam is fitted and the carburetor is adjusted to suit ( not to big -not too small==just right )
tyre pressures are correct and the possible fittment of an overdrive unit to the gear box (if manual ) to lower engine rpms when on the highway, you may get better economy

Most likely the fuel pump is not running because the crash sensor, aka the fuel pump cutoff switch, has tripped. They usually have a reset button on them and are located by the in line fuel pump.

When im going up a hill it downshifts on me and it dont have a lot of miles in it i need help


It is 5 or 6 years old

Miles mean very little,when your have problems

We need much more; than it downshifts

I suspect, if I drove it, that it has more drivability
issues.

The only reason it downshifts is the shift stratagy
was set by the PCM (computer)
So I suspect you have done no preventative
maintenance,based on your logic of low milage

You have to get back the engine performance
to clear up your shift issue.

No Codes or any lights on dash
New spark plugs
5W-20 oil your supposed to be using
New Air Filter
New Fuel Filter
And much more.

I'd be tempted to have fuel pressure checked, if at all possible, when it quits. If nothing else, carry a can of quickstart with you, and when it quits, remove air intake at throttle body inlet, and open throttle plate and give a good squirt of quick start, then try to start it. If it starts for a second or 2, then you know you have spark, but no fuel. I've seen fuel pumps work good while cool, and cut -out when it gets hot. Then sit and let pump cool off for 20 minutes or so, then pump up to pressure again and away we go, until it gets hot again. You might also find if you park in the shade, you'll get further, or even on a full tank. Another good idea would be to change fuel filter in case fuel pump is working too hard pushing fuel through a plugged filter, and causing low fuel pressure.
