Last few days the truck was a slow cranking up in the morning. Didn't think much about it since at the end of day at work it would fire right up. Well today same thing happened at work with slow start. But also I noticed heavy black smoke coming out the exhaust. Also, seemed to have lack of power taking off and with heavy black smoke. Once the rpms kicked in all was good. Anyone know what could cause this issue? I am thinking that the black smoke has to be unburnt fuel. So maybe issues with the fuel injectors or something?
You need to scan it for codes first, it does sound like the FICM tho.
Is the ICP sensor in the right valve cover or under the turbo? Pull the connector off and look for oil, if you find oil replace it and the pig tail.
Well truck has sat home for two days and the batteries are way down. Was only able to start the truck with my Jump Start. I had replaced the alternator about one yr. ago from local Advance store. Maybe my alternator is also going bad. My friend has is a mechanic is coming by tomorrow to see if we can pull some codes.
Well my friend came over and did his thing. The truck wouldn't start without the Jump Start connected.He 1st checked the batteries for voltage and they were down to like 7. something volts. No codes could be found. He said that they might of cleared since the volts were way down. I know I unhooked the battery cables the day before to clean up the terminal ends and the battery lugs. Would doing this clear the codes?
I hooked up the jump start afterwards to start the truck for him. He said it throw some Black Smoke on start up and also had terrible miss. Once it ran for a while it seemed to get better. Checked my charging system and alternator output. All was showing it was working right. He noticed that one battery had a low level battery cell when he removed the battery cell cover. He suggested I take the batteries to parts store for free load test and charge. Could a low batteries voltage have cause the issue with lack of power and the Black Smoke out the exhaust?

When you say slow cranking do you mean it had a long crank time or the engine is slow to turn over? If it's slow to turn over then you have a voltage problem, if it cranks at normal speed (150 rpm) then you have another problem.
Long crank times on this engine can set false CKP and CMP codes (P0340 P0341 P2614) it's pretty rear for those to fail on this engine.
You need to have good fully charged batterys before you diagnose any no start problems.
Check these things, FICM voltage, ICP pressure and for oil in the connector, fuel pressure, see if SYNC changes from NO to Yes when cranking, and that the engine is full of good clean oil, I had a no-start 6.0 this week that ended up being out of oil,
and check fuel pressure.
One of those is going to send you in the right direction, I work on these every day.
Thanks! Almost tempted to trade it in if I can get to run some what. The truck is really more then I really need. All ways have problems parking in downtown and alot of underground parking garages won't let me park there cause it is too tall or oversize.
When my batteries were low on my 08. the truck would smoke. I replaced the alternator and recharged the batteries and everything is fine. I feel the glow plug was not working 100%.
I am at the store now. One battery was bad. Purchased another online from Advance and used a online Advance Coupon Code. Saving $40.00. Other battery scanned good but low on volts. They charged it, then checked again on scanner. Now scanner says it still has low volts but now at 13.01. So they are recharging it again to see if it will pass on the scanner also.
You need to check your FICM, alot of times when your batteries are weak you end up killing your FICM. Do an internet search to see how to check it with a multi meter-it only takes 5 minutes. It should be @ 48 volts KOEO as well as while cranking. If you have access to a scanner that you can watch voltage it makes things easier but either way it only takes a few minutes. Also make sure to check this when the engine is cold like first thing in the morning.
This. Don't be a fucking cheapskate and create more problems down the road. Once a battery has been discharged enough to not start the engine, you've lost most of the reserve capacity and it will never be as strong as it was. You may get it back up to 13.6v but it won't hold it under load.
Alright, I installed the batteries and she fired up. It was throwing out more Black Smoke in the beginning and missing alot. Once she warmed up it got alot better. I Topped Off the Diesel Fuel in the tank and also added some Lucas Diesel treatment. I ran it very hard and seems Great! I will be trading her in once I get the new title from DMV. My old title had a lean from HSBC. Since truck is Paid Off I need a new title stating No Liens on it.
