Need some help!

I am having troubles with my truck it starts ok but when I accelerate it is just missing like crazy. I had a new FICM put on last year now my scanner (which is a Actron) won't read anything. Before I had the FICM replaced my scanner worked on it. My truck is not throughing any codes but my machanic and I are tring to run some tests on the injecters and his scanners can't read anything either so he gave Bullitproof Diesel a call and they told him he needs a Ford IDS scan tool. So my question is, is the new flash for the FICM the cause of this and if so how does this affect my tuner when reading the out puts of the engine? Any help would be appriecated.

This may sound stupid, but check your fuses. Is your cigarette light working? That is on the same circuit as the OBD connector IIRC. I thought my AE was messed up on my son's truck but it ended up being that blown fuse.

The Actron is just about useless for diagnosing these trucks. You need one that will read most of the Ford Diesel PIDs. As suggested, a tool like the IDS, is needed to diagnose problems beyond the ability of a good diesel monitor. The Ford IDS is out of the ball-park for most of us dollar-wise, even if we can get one or the keys for it. Maybe the next best thing is the AutoEnginuity with the Ford Bundle for $360 as a hard diagnosis machine. This one will let you do a number of the interactive test needed to properly diagnose injectors.

Yeah I had seen that on another post and had my machanic check the fuse and it was good but thanks for the input.

I see you have a Dashboss I just ordered one the other night. Will it help to see what the injecters are doing? Thanks for the info.

DB gives a vast amount of PID info and is very easy to set up. However, it is not an interactive diagnostic tool. To troubleshoot the injectors, you need to be able to commanded the injectors, do a buzz test and perform a contribution balance test. Another very useful function is the ability command the IPR for HPO diagnosis as well. Right now, the best/least expensive option is AE or take it to a shop that has the tools to do it. However, the test should be performed cold, so expect to leave it overnight. If it is just done warm, it often misses stiction issues.

In the future it may be possible for a monitor like DB to do some of these interactive tests, but programming and testing cost money. Someone will have to pay for it.
