6.0 won't start!!!!
I have a 2005 f550 with a 6.0. The injectors were giving us fits so we replaced all of them along with new standpipe and plugs. It ha been running perfectly for 2-3 months and now, all of the sudden, this morning it wouldnt idle worth a crap. When you try to start it it would just start super slow and then finally catch and spudder and shake like only half the cylinders were firing.
We put it on our genysis scanner and got these codes: P0611 ficm P0262 P0270 P0277 P0278 P0280 P0284 P0528 We read that injector codes coupled with the ficm code told us the ficm was bad. We ha suspected this for a whole but this convinced us. So we replaced the ficm half she'll and it did not fix the problem. We have good logic and and vehicle power. Also ficm power never drops below 47. We are at a loss. Also, upon first start up the blew black smoke pretty heavily. Also the truck is running very loudly on top of loping at idle. |
have you cleared codes and see which ones reset? Are you sure ficm connectors and connected fully? Oil level good? fuel press good? Also check battery connections specificly the one ten mm nut the holds the power cable to the ficm on the driver side batt. post cable end.

check the filter inside the frame rail if you see what looks like silver whitish paint chips thats bad probably took the pump out check and see if the top filter housing fills up the silver paint chip shit is from the shit in the tank iv seen this tons of time at our shop with the 6.0's and it also takes out injectors like its its job lol

We pulled the filter and it filled fine and was clean.

Do you have access to a scanner? You need to check your icp desired against icp actual. Just fixed an 06 not too long ago with same issue
