Hard start? Video inside...

[ezdubbin97]

Hey guys/gals.

Been about 3 weeks since I had my headgaskets replaced by a reputable Master Tech @ our local Ford dealership. I have the utmost confidence that everything was done right and put together correctly as it should have been. Before I had this done I had experienced longer than what I thought it should be starts on occasion.

While he had it apart, I had all the upgrades done for the areas he was working in (stand pipe, dummy plugs, STC fitting, HPOP screen, etc, etc...). Since I have gotten it back about 4-5 times I've experienced a realllllyyyyy long crank until start.

Any ideas of where I should start looking?
Is it abnormally long or something everyone experiences from time to time?

This video was taken on my lunch break this morning @ 3:10am. It had sat for about 6 hours and the temp was about 35-40 degrees. Feedback is appreciated...Thanks!!

Well, mine was taking a lot of cranking to get it started before the FICM finally died.

Might check for codes - if you see any low voltage injector codes, it's a sign your FICM is getting weak. You can get a few low voltage injector codes without the CEL light coming on.

Doubt its the FICM, I replaced it in January, but yeah, I know what your talking about with how it acted before replacement.

I have no codes other than the P03336 crankshaft position sensor code that pops up after long cranks.

Anyone else got any input? Went out again last night, same time, sat for the same amount of time, and same ambient temps...started within 1-2 seconds. hmmmm....

mine does the same thing, its just kind of hit or miss, doesnt really bother me as long as it starts im happy, it actually did that yesterday in 30 degree F temp, got home sat for to hours then ran out and started within 2 seconds

looks like 4 to 5 seconds...I'm having the same thing. Only when it has been sitting for a while. If it's been running within the last hour or so, it fires in 2 or less (I've taken to counting every time I crank it).

When I did my delete I did the STC fitting too and for a while it fired right away no matter what. Then this started. I don't think it's dummy plugs or stand pipes because it fires so fast when it's warm. (I think this rules out STC fitting too)

Sinner mentioned to me that it sounded like maybe oil drain-back. I watch my insight and it seems to be taking that long to build up enough ICP to fire. He said this can happen when people use oil filters other than Motorcraft. I'm only using Motorcraft, so I'm not sure.

Not sure if this helps, but maybe can help you rule some things out and maybe I can get some ideas in the process.

Good luck

I'm with ya Hank, just those little things that burn me when I know something doesn't work like its supposed to...plus I get weird looks from all the Cummins guys at my work, makes me look bad

I'd like to monitor my ICP, but, I have yet to find the proper PID in my Livewire to so. I know they did an oil change, being a Ford dealer I would hope they used a Motorcraft filter LOL... If anyone has a clue of how to monitor the ICP on a Livewire, let me know, I'm clueless
