I put my new ficm in that I got from Pensacola diesel. I am getting 48.5 volts. I have an sct x4 scanner that I’m monitoring everything in and my truck still won’t turn on and doesn’t have any injector clatter. I don’t know what could be causing the issue still besides maybe the fact that the ficm will drop down below 46 volts while cranking but idk why that happens when it’s a new ficm. Please someone help me get my truck running again.

First thing I would do is go back and reseat the connections to the ficm making sure they are fully connected. Also, were you having this issue before you put the new ficm in? It also helps the more knowledgeable folks to have the details of what year model you have, with mileage and any major modifications listed.

Hey guys sorry I didn’t see y’all replied. I have an 04 f250 6.0 power stroke with 156k miles on it. Originally I was getting clatter every now and then and was getting codes for ficm preformance and ficm low voltage as well as when I throttled hard I would have misfires. I bought a 48 volt ficm from Pensacola diesel and I posted my problems on a Facebook forum and everyone told me I had a bad ficm( the one in the picture) so I used my warranty and got a new one. Well when I plugged the new one in yesterday it would drop from 41 volts down to 2 volts like my orginal one did. I’ve checked the red fuse under the hood and it’s not broken. I’ve checked the fuses under the dash and they’re all good. I tried posting a video but it wouldn’t upload but everything is good it’s just not getting injector clatter.
