Hard to start and codes showing injectors

[fayeandi]

Hi everyone,, from start to end,,, 2007 F350 bought brand new. First winter the filter gelled up and had two injectors go bad, then 6 months later 1 more etc until seven of the eight were replaced. It ran perfect for about a year then about 2 weeks ago I got a code saying # 7 injector ,,, but NO missing , we cleared the code and waited, then it started hard for the first time since I bought it, and after that strange thing, # 4 injector showed bad. I cleared that and then # 7 came up again. NO missing etc, The next morning it started real bad and after it got going , it ran perfect the whole rest of the day. OF COURSE I am getting ready to DRIVE to Mexico city from MN and the next morning it took , like an hour to get it running, black smoke/ white smoke fire, quit , crank crank, and finally it started, and again ran PERFECT half way to Texas,, next morning it took AAA like two hours to start it,,, codes showed ALL injectors bad. then I knew it was going to the shop. In Buda Texas the Ford truck shop said the FICM was bad. 1200.00 later we were on the road and we have put on 5000 miles in the last week and a half,,, runs perfect , starts good etc,,,,, WHY does this go out and why does it cost so much.... ?? Does replacment FICM's go bad?? I love my truck, but I'm a little jumpy now.

Sounds about right to me. The only thing that I don't understand is why you got charged $1200 to replace the FICM on a 2007 truck. Did they void your warranty for some reason?

Are the codes for Injector Circuit too low/high? If so, I'd be thinking your replacement FICM is bad.

The way I read it, the truck runs great with the new FICM. Just trying to figure out why it wasn't covered under warranty.

The truck probably already has over 100,000 miles on it. If not, they should of replaced it under warranty without a deductible because of it having to do with emissions. (blowing smoke on start up)

Sorry guys,,, forgot to say, of course over 100,000 miles,, did buy extended warranty, but just before the 100,000 so it does not cover the fix,,,, the codes said LOW voltage on injectors. Question still is,,,, will this happen again???

That happens with the FICM fails. It might happen again in 100,000 miles... nobody is sure. Next time, buy an FICM from Swamps and have it programmed for significantly less than $1,200. Or take off your FICM and resolder it yourself and see if that works... many people have had good luck with the do-it-yourself resolder fix.

For now, I don't think you have anything to worry about.
