joshbuys Posted December 18, 2012 Share Posted December 18, 2012 Ok, this is all second hand info as I have not looked at the truck myself, it's at another shop that calls me from time to time for help, 2003 6.0L, all 8 injectors replaced about 10 months ago, has been fine up until a week ago when it died, then it would start and die, FICM voltage was low so they put in a FICM, now it runs, but it had a miss, 2 and 7 were contributing low and the fuel pressure was low, they replaced HFCM, Fuel Pressure Regulator - 9T517 - and injectors 2 and 7, now it runs smooth hot, but injectors 2 and 7 are contributing low, he says the negatives seem to jump from injector to injector(going to all 8 injectors), but seem to hit 2 and 7 more often than the others, once it has run for 5 - 10 minutes it seems fine. I'm going to take a look at it tonight or tomorrow night, I told them to check for exhaust gasses in the fuel (although I would expect this to be more consistent, and get worse when it's hot), check the cam/crank sensors...looking for any other ideas as I have to drive a ways to get there and would like to be able to check everything in one trip. Thanks in advance for the help! Quote Link to comment Share on other sites More sharing options...
Brad Clayton Posted December 18, 2012 Share Posted December 18, 2012 Recheck that FICM, I have had more than 1 that was bad right out of the box. Quote Link to comment Share on other sites More sharing options...
