Serious cold start problem!!

hey guys ok so I've been having horrible bone chilling cold start issues the last month or so. If its below 45 degrees it acts like its below 0. Horrible horrible shaking and coughing. Its the typical 6.0 sound like its miss firing for a while. after that and it begins to warm up all is well and no issues at all. So I dont believe its an injector issue. I kinda think I have some bad glow plugs. when I turn to warm it up before starting you can hardly here the BUZZZZ sound it normal makes. (I think thats glow plugs) and heres the worst part, I have REV-X in my truck and I know that stuff works so something is going on with my truck! could it be glow plugs or something else?

ANY HELP AT ALL PLEASE!!

Check FICM voltage. Guarantee it's dropping way below 46v causing your issue.

Best bet

I have had this very same problem for the last 2 years. I have been getting by with plugging in the block heater. The truck will at least start and run that way, but still runs very rough untill it warms up. My problem got worse and worse as time went on, and finally the other day no start. After much research online and many phone call to various mechanics, I discovered it was the FCIM, that is "fuel injector controle modual" notorious for failure. After much effort to get started took it to have the FCIM tested and sure enough thats the problem. A new one will cost $600 to $700 plus the labor (not hard to do yourself), but don't dispair there is a company on ebay in fact several that, clean, repair, and rebuild, for $55 to $110, and offer lifetime warranty. You remove it send it, they fix it and send it back.
6.0 powerstroke fuel injection control module | eBay
The people doing mine are

69 bucks lifetime warranty they pay shipping. GOOD LUCK

thanks for the replys guys. and trust me I sure as hell hope its not my ficm. especially considering I had a recalibrate flash from PHP done to it only like 6 months ago. I thought that flash was supposed to eliminate the ficm problems.

could this still be the issue or something else now that yall know this?

The noise you are hearing is the fuel pump cycling

Not a soft problem the FCIM power supply fails the sotter joints fail over time with the heat and vibration.

You won't lose the PHP recalibration because that is on the logic side. Your problem is the power supply side.

so this means I could lose that flash code I put onto my FICM over time? haha if so I'm not gonna be happy I paid 150$ for that programmer flash. I'm gonna try and get the tool to test the voltage on my FICM though.

But heres another thing I've been hearing it could be weak injectors and thats scary cuz I know how expensive they are. when it starts rough in the morning it coughs black smoke until it starts then its kinda whiteish steam more than anything after that and when it warms up it stops. thats not injectors is it?

The injectors are fine. Put a new power supply for the FICM in. You WILL NOT lose your PHP programming.
