Hard start/No start

--------------------------------------------------------------------------------

Howdy All;

Just recently joined like many do, I have a problem and would like to tap into the knowledge base.
Engine is in an Early ( Man'f'trd July 25 '03), 2004 F-250.

Problem; Hard start/No start

Clues;
Started this past Winter, Had org. batteries (changed out 2 weeks ago), and even when it was only mildly cold (20's - 30"s) was a hard start unless I had plugged in the block heater, then it would start as you would expect it to.
Now (I'm in Southern New Mexico), with daytime temps. into the upper
80's and nights down to the mid to upper 40's, it just wants to crank and
crank and so on ... Again, unless I plug in the block heater. Even if the
outside air temp. is in the 60's or low 70's. Plug in wait 3 to 4 hours,
extension cord (heavy duty), feels warm. Unplug, turn key on wait till the dinging noise stops (another hint), I can hear the fuel pump whirling, I wait till it stops then engage the starter. Cranks but starts (yea!!!).
Then I have to wait for several (5-10), minutes while it smooths out.
Rough idle, slight raises and lowering of RPMs (very slight). Sounds like an old 50's Detroit ....
Power is weak for the first few miles then it performs as it should.
Both fuel filters have been changed and it still is the same. Need to change engine oil and filter, picking them up Monday (5/13/13).

Ok, that's what I can recall in the condensed version....
Any ideas? Thoughts? Conjectures???

Ask me questions I'll answer best that I can.
Thanks for your considerations.

Check your FICM voltage.

Don't wait for your fuel pump to shut off before attempting to start the truck. As said, check your FICM voltage, but it really sounds like a major case of stiction. Before you dive in and replace or fix the injectors (see my sig) ensure you have good HPO pressure for the start. If your HPO pressure is good, you definitely need an injector buzz and power balance test done (cold) to determine which cylinders are under performing. Where you live, you don't need a block heater.

You could try using 5w40 synthetic to see if that helps out. ensure you use an OEM or EXACT FIT oil filter.

twoicebergs, Howdy;

Thanks for the reply. I realize that due to my locality I don't need to use
the block heater. However, in order for me to get the engine to start, I have
to utilize the block heater.
Is there something that the block heater is doing (other than misleading some sensor
and if so, which one), that makes the engine (computer), believe it's good to start???
Simply attempting to eliminate as much as possible and get it fixed with a minimum of
knuckle bustin' and cussin' .... I truly hate it when an inanimate object gets to be smarter than me.
Again, thanks for the response.

All your block heater is doing is warming things up and in the process, thinning the oil to help prevent sticking of parts with oil varnish on them. If you had a gauge on it, you would find your engine would be 70* or more, depending on the OAT. As you said, at 40* it doesn't like to start or run. This is classic bad (more than 2) stiction. One other thing that may be a secondary factor for the block heater is you may have some glow-plugs that are not working correctly.

It not only doesn't want to start when the ambient temp is 40*, It doesn't want to start when the ambient temp Is 95* unless .............
it's plugged in.
Changed oil filter and now discover that Wicks are not recommended.
Some are saying to shift back to OEM's... Reason they gave was they (Wicks),
have holes to small and will restrict the flow, that goes for fuel as well...


Thanks for the inputs... still :scratchhead:

As switch back from WIX you will need an original oil filter housing cap as well. You can't use the WIX cap as it is too tall. I don't recommend WIX because my truck had one when I bought it and it was disintegrating. If I had not changed it, it could have ruined the engine!

Let us know when you get a monitor for troubleshooting or when you get it scanned.

Still using the cap that came with the truck. Has a nice yellow dot on it.
But thanks for the heads-up on it though.

I'd definitely check your FICM voltage. My truck was doing the exact same thing..I live in NY, but this was the first winter I had to ever plug my truck in. I bought an Edge CS and my FICM voltage was reading 23.5! (not good at all) so I took her out and sent her in for repairs. Especially since you had old batteries...bad batteries can fry the FICM real quick.

Howdy All;


I have changed out the Wicks filters for Motorcraft, the caps are all org.

Last Summer I had some work done to it as I was noticing an oil leak thought it was Rear Main Bering, turned out to be the ICP. So it was replaced but not the plug mechanic said it was in good shape (clean).

Left the truck un plugged last night and NO start this Am.

Plugged it in and now waiting for the heater to 'do it's thing'. I'll edit this when the time passes and let you know if I can get it running.

Have not been able to check FICM voltage ... (yet!), will be doing so soon

Appreciate ya'll taking the time to help me solve this puzzle.

EDIT;
After 2.5 hr's. wouldn't start... tried real hard but nothing after 2ed attempt. walked away for another 2 hr's. Tried harder , ... almost caught
it tried to do a rolling start but didn't quite make it ... Left it un-plugged, will re-plug it before I turn in to night.
