Hard to start

[RJ's325ITS]

I need help with my 2001 F250.

I rebuilt the HPOP and the fuel bowl a couple of months, everything was fine until a bout 2 months ago.... I started to notice that it was taking longer to start, and it kept going worse to the point that I'm not driving it anymore.

Here it is what happens:

Key on
wait for the WTS light to go off, and
at this point an proceed to crank the engine
it rotates but it wont fire
key off, and repeat
then the second time it actually fires up..

Once it's running it runs fantastic but once I have to shut her down and crank it again, then fail again it takes a lot to get it to fire up again even after it's fully warmed or had been driven for a good while.

I'm not a truck guy so I really need some pointers where to start or what test I need to start with.

Thank You guys.

Rafa,

you might want to check the injectors. my 99 had the same problem

Could you elaborate on how did you test the injectors, and how did you fixed it?

Thx

after fighting it for 3 months i took it in to ford and they buzz tested them and found that 5,7, and 8 were bad.

Here's another idea as well... Dirty injectors will make it difficult to start, you could pick up some injector cleaner and run it through and see if it gets any better, also have you checked your engine oil? If your oil is low your injectors wont' function properly.

Okay guys oil level is fine
Recharged the batteries (just in case)
Visually inspected the engine bay - nothing out of place

BTW I realized today that when I press the accelerator multiple times while cranking it, it starts right up!!!!!!

Before you go waste money on testing injectors, start with this.

-Not sure what oil you run, but in the winter 5w-40 will help with cold starts.
-Clean battery terminals, and fully charge batteries. Low voltage will cause your motor to not only crank faster, but not run at it's best.
-Check the Glow Plug Relay (they are notorious for burning up)
Winter Operation, Hard Starting, Hissing Sound Etc...
Stancor Relay Mod!!
-If the GPR is bad, replace with a Stancor relay (around $50 shipped)
-Glow plugs can be replaced for around $80 (go with motorcraft)
-Try plugging your truck in 3hrs before cranking
-A properly working GP/starting system on these trucks will be able to crank at -20 degrees F w/o being plugged in.

Let me know if you need any more help.

Oh yea, don't cycle the GP's...it does nothing but wear them out faster. Don't begin to crank when the Wait To Start light goes out, the GP's will remain hot up to 2mins depending on surround temps. Give your Gp's 45+ plus before cranking to see if it helps.
