Starting issue

I just bought an 06 f350 6.0 a few days ago and noticed it takes a minute to start up. I’m relatively mechanically inclined but this is the first diesel I’ve owned so excuse my ignorance as to how things should be, I know it won’t start as quickly as a gas engine and don’t expect it to but when it’s been driven it starts up quickly however after sitting all night it cranks for a handful of seconds before firing up, is this to be expected or is this outside the norm. Like I said I don’t know my as-s from my elbow when it comes to Diesel engines just trying to figure out what is and isn’t normal

Re: Starting issue

What are the outside temps when you're attempting to start it up? Also, are you waiting for the glowplug light to turn off before attempting to start? It is normal for a diesel to take longer. In fact, Ford says 3-5 seconds is acceptable for this engine....though I've never had it take more than 2.5 or so.

The outside temp is around 80 in the morning and mid 90s in afternoon(SE Texas) so I don’t think the temp is the issue, I do wait for the gp light to go off although it’s almost immediately I still wait a couple more seconds.

Re: Starting issue

IMO, if it's taking more than 2 seconds to start when it's that warm, and you have waited for the glow plugs, then you may have an issue. I would hook up a scanner while trying to start and watch your IPR/ICP to see if it's taking longer than normal to get the right pressure from the HPOP. If the pressure is up above 500 and it's still waiting a bit before firing, I would check the glow plugs with a multi-meter.

I took it to the dealer two days ago and told them what was going on and they said they’re going to take care of it, should be ready this evening so we will see what they do or don’t fix on it.

Re: Starting issue

Please keep us informed. As Weatherlite posted, the one thing you need with a 6.0L is a scan tool for reading engine parameters. The most cost effective ones are smart phone apps - Torque Pro or ForScan Lite. You also need an ELM327 OBDII adapter with the software. ForScan is a better code reader.

That said, your issue sounded like either a leak in a dummy plug (high pressure oil) or a FICM issue.

Guessing gets expensive, thus the scan tool recommendation.

Even if you take it in, a little knowledge can keep the shop "honest". For example, your HPOP is VERY reliable. Hopefully they do not charge you for one (it is a common way for them to make extra money)!

They didn’t charge me anything, said they changed the fuel pump but that did absolutely nothing. Still same issue, I will be getting a scanner. What am I looking for on that scanner to see what isn’t right

Re: Starting issue

The best scan tool option currently (IMO) is a phome app called ForScan Lite. With it, you will need an ELM 327 OBDII adapter. I like BAFX brand.

With it you need to first check codes.

Then monitor the following when cranking:
ICP pressure
ICP volts
IPR % duty cycle
FICM MPower
FICM LPower
FICM VPower
rpms (again - when cranking)
FICM sync

Does anyone know a store that carries a decent scanner/reader? I’d prefer not buy online if I can avoid it.

Re: Starting issue

i think oreilly's and autozone have a version of the elm adapters, but they charge like $60 for one. Online they are literally $10 sometimes lol

I second the FICM voltages! :p my FICM main power V was at around 30 Volts cranking on cold startup best i remember when I started trying to figure out a long cold crank and a cold misfire type issue. I was misled because by the time the engine had warmed up, that same voltage value increased to the appropriate 48 volts. I should have read that value on cold start long ago.

Oh, a rebuilt ficm solved the long cold start - went from and ugly bloppy 3 plus seconds to a snappier "rin-rin-rin-rinBRAPAP-PAP-PAP-PAP-PAP-PAP...." It also helped the cold running/misfires tremendously, but it's still there just a tad. i'm guessing sticky injectors now
