hard start when cold

My buddy's 06 with 100k on it has been acting up.He says that when the truck sits overnight it starts kinda hard.After it starts it will run real rough,if he doesn't let it warm up and trys to drive away he has no power and it stumbles.If it has a chance to warm up it runs ok.

Any suggestions on what the problem may be.

He's just north of Tampa so if anyone knows a good shop let me know.

The Fuel Injection Control Module (FICM) has lead free solder connections onthe circuit board. Due to no lead, the solder is very fragile and will develop hairline cracks. These crack prevent full electrical connectivity thus reducing the voltage in the circuit panel. If you plug the truck in for a few hours to heat the engine and oil, the heat inside the engine compartment will cause the hairline cracks to tighten up thus providing the required voltage for the engine to run properly.

It may be hard to believe this but mine was doing the same thing. Check the voltage on the FICM and see if you have a low voltage situation. You may also have a P0611 code which indicates the FICM is on its way out.

Mine was just repaired at FICMrepair.com today and is on the way back to me. I should have it Monday or Tuesday.

Thanks.....I'll let him know.

I do know that he did have the FICM replaced about a year ago.I suppose it could have gone bad again.The one he had put on was a refurb but i'm unsure from who.

Anyone know any good shops in the Tampa area where he could have this changed out.

No ...Tom can't find where he put it and i didn't think to save it.

I'm going to suggest to Tom that he order one from FICMrepair ,take it to that guy in Tampa and have him do the sawp then Tom can send the core back.

My friend is on a fixed income(retired) and i sure hope his truck doesn't start to eat him up in repairs.He's got 104k on it and generally runs good except for this hard start issue when cold.

Thanks again for the name and number.
