Hello I have a 2006 6.0 f250. I had a bad injector number 5. I tested the injector with a ohmmeter and then my chip that I have on my pickup told me that it was going bad. As I was driving it if you gave it a lot of throttle it would lose power or even to the point where I would die. I bought a new injector and replaced number 5 injector claimed out holder hole torqued to 30 lb. And put everything back together cycled in a few times to prime it. Started it ran for 5 minutes then Rev then died then revved then died then revved and now I can't get it to start not even with ether you guys have anything that might help me?

Might be the FICM rather than the injector you swapped out. A friend's truck had a problem with the FICM (no-start). We couldn't get my scan tool to connect, but the info we did get pointed to either a bad injector OR the FICM. He took it to a shop and they replaced the FICM and he was good to go.

I will check the FICM out in the morning. That's probably what caused it to start running weird. If it ideled for like 20 to 30 minutes before going some where it would be fine. Sometime a hiccup here and there. And if it was cold they would drive a little ways and then just died that was before I fixed injector.

I got the truck to start. Atlantic warm up for a little bit 10 minutes or so and then I took it for a drive when I got to 2000- 2200 RPMs it just lost power no throttle response felt like pickup died and then restart. The truck would pick back up and idle as long as I kept the truck under 2 200 RPMs it would drive normal could this be the ficm

It could be the FICM. Dying or losing rpm's at 2000 rpm is more of an IPR behavior, but the FICM and IPR valve are the most common reasons. I wouldn't buy a new part yet. Get a scan tool and monitor a few engine parameters to see if you can get an idea what might be causing it.

You can download ForSCan Lite to a smartphone for a few dollars and then buy an ELM327 OBDII adapterfor about $30. I like the BAFX brand of adapters (WiFi for iOS and BlueTooth for Android). ForScan is a great code reader also!

You could try disconnecting the ICP sensor to see if that is perhaps causing the issue (it sometimes can cause your issues).

If you really think it is the FICM, I would send the FICM to FICMrepair.com to have it tested first. They are honest and wouldn't tell you it was bad unless it was. Then (for cheaper than a new FICM) they can repair it w/ upgraded parts.

The best scenario is if you have a spare (known to be good) FICM that yu could install as a test!

If you get the scan tool, monitor the following when driving:
ICP pressure
ICP voltage
ICP desired
IPR % duty cycle
