Long crank when cold. What to look for?

So I have an 05 Excursion with a 6.0. About a year ago I had the motor pulled, Studded and everything that needed upgrading done. I have the EGR Cooler welded shut. Anyways the past couple of weeks it has been taking between 4 and 8 seconds to start up. It used to only take maybe 3 seconds.

I have the torque app that I just hooked up yesterday. On the app I notice the FICM stays at 48V sometimes it drifts down to 47.5V.

It seems to start up normal after I run the truck. So only when its cold is when we have the problem. Could be a glow plug issue? Is there something on the Torque Pro app I can monitor for glow plugs?

Any Ideas? I do have a volt meter. Do you guys think I should test the FICM that way? Or is the torque pro adequate on the FICM. Once the truck starts it runs perfect. No missing, No smoke. I do have the Extreme Street Tune on the truck.

Any Ideas? Thanks for the help

Couple of things you could try, first you could try parking nose down and see if that improves the time required to start and the next would be to heat the FICM with a hair dryer and get it warm then try and start it. FICM problems usually show up on cold start events and even though the voltage may show good they can still be failing.

I will try that nose down next time. What does the nose down accomplish? Is it where the oil sits on the pan or the fuel in tank?

If the HPOP has bad seals it can allow the HPOP reservoir to drain through the pump, if you park nose down it puts the HPOP higher than the oil level in the reservoir preventing it from leaking back to the crank case.

I believe your torque app also monitors ICP and IPR% IF so monitor these values while starting in the mornings.

Try what Brett said it's an easy way to start and what lead to how I found I had a bad pump. reps sent Brett!

The ICP shows up as HPOP. If so I already was watching it. Not sure what pressure it needs to start up. I know at idle it is 584 psi. I did add the IPR% to my app but I do not think it communicated that value last time it was hooked up. I will check again after work. Thanks for all the advice guys..

You need to watch it while starting you need 500 psi to start, see if it builds slowly as you are try to start.

I just started it up. The HPOP seemed to go from nothing to 780psi, but this was when it cranked up. I guess the blue tooth is slow to send the info to the app. I will keep watching this everytime I start it. I did notice that the battery voltage was showing 11.9v when the glow plugs are supposed to be working. Is this too low? It took about 5 seconds to start this time. I killed it after it ran for about a minute. I restarted the truck. Then it started right up within 2 seconds.

Ok guys. I parked the truck nose down last night. It still started the same. How can I test to see that my glow plugs are working properly? Or if they are even coming on. thanks for all the help.

Did you try warming the FICM up with a hair dryer? Heat it from the bottom. How long does the glow plug indicator stay illuminated?

I didn't try the blow dryer. I will try that one later. The glow plug indicator stays lit for about 4 seconds. Which is the same as it always has been when cold.

Warmed it up with hair dryer for about 10 minutes. The outside of the ficm was nice and toastie. Still took about 6 seconds to start. I am guessing it has to do with glow plugs.

You could try leaving the key in the on position for around 10 seconds before attempting to start it. Another thing you may try is disconnecting the ICP sensor located on the passenger side valve cover, while you have it disconnected make note of any oil in the connector reconnect it and then start it.
