Ford E450 class c with V10 slow to start sometimes

[Matthewc45]

I have a 04 class c with the v10. After it sit for some time it will turn over for 5-10 sec be for starting up. It dose not do this all the time mostly after it sits for a week or two. It has done it a few time while stoping for an hour or so. All other time she fires up as soon as you turn it over. Just wondering if this is normal?

I had the same issue.
It was the regulator in the fuel pump. I was losing pressure.
Mine never failed on me. Just aggravated me.

Wow .... can this be done when on a trip?

I thought the Ford V10 fuel pump was inside the fuel tank and that it was a fairly major job replacing it - emptying the tank, dropping it, changing out the pump, lifting up and rebolting the tank in place, and then refilling it with enough fuel to get to a gas station, etc.. :h

I am hoping not to have to change it but if I do I will do it myself. I have done much larger job on the side of the road to 18 wheelers. This would be a large job but I have look at it and there is a drain plug in the bottom of the tank an 5gal bucket will fit under it. So if it dose fail then I have a plan. I have changed the fuel filter today and it has started good the few time I have check it. I also had the wife turn the switch on and I can hear the pump running. So I am praying for a problem free trip. The wife always says that I cannot leave things along until they are broken or I find a problem. Thanks for all the feed back I am starting to like this forum more and more.

Absolutely. Restricted fuel filter slows fuel flow, which is what cools the pump. Less flow = more heat = short pump life.

The higher the head pressure the shorter the life typically where in a MH or your chest.

I am going to change the fuel filter this weekend and hope for the best on our trip. If the fuel pump goes out on the trip I will just have to change it than. Going to bring all necessary tools with me to do the job on the road. Thanks for all the help. Going to be running some Lucas fuel injector cleaner in it so hopefully that will help lube the pump.

If you want to change the Fuel Filter here's a thread about it. It's easy, but it helps to be sure which end goes which way and to get the correct one to be able to change it again the next time. There are pictures illustrating that.
I'm sure Bryan's point about a failing fuel pump is correct. It's also my belief that a clogged fuel filter shortens pump life.

This is often an early indicator of a worn out fuel pump. How long can it go before it fails? Who knows. My old van was like that for about 4 years before I finally replaced it (after it also started hydrolocking in hot weather). My brother's Expy currently does it too but he'll probably wait until it fails to change it.

Thanks for the responses. It starts fine most of the time it just every now and then it dose that. Just trying to get some ideas as we are about to head out on a 1800 mile trip with it.

It doesn't really sound normal. I would have fuel pressure checked, might be bleeding off due to leak or bad regulator, or fuel pump going bad. Or maybe fuel filter slightly clogged. Any of these problems can equal a no start some day.

Hi,

You can turn on the key, then wait 10 seconds for the fuel injection system to pressurize, then turn to the "Start" position. It should start with minimal cranking at that point.
