Problems completing 7 pin FICM repair

Following posts here I have determined my FICM is probably bad....down to 18 volts while cranking and almost starting. I have removed it for resoldering but am having difficulty splitting the case after removal of all the Torx head screws.
Is there something else holding this thing together? I can only split it about 1/8 inch. How rough can you get with these things? (It is the 7 pin unit, early 2004) Tks for any help. 2004 SD KR 120,000 miles.

I have heard you can take a hair dryer or heat gun and warm the case, sometimes the insulateing gunk melts and sticks to the cover and the circuit board. Heating it will soften it should make it easier to seperate. How rowdy ya can get with it is subjective just remember it is a piece of electronics.

did you remove the 7 screws under the the plate aswell? I did the repair on my 04 today. I have the 4 screw. But you have to remove these screws also. After the reflow of the 16 spots mine will start right up and idol great but has no power when driving. Before the repair I just had to keep it pluged in or it would not start first thing in the morning. Sence it changed after the repair I guess I got some of the spots good and others not so good. Looking for someone that know which spots to reflow or if I need to reflow all.

I have a 7 pin and going to yank it apart this weekend while it is out so I can replace the IPC behind the turbo .

Starts ok I guess but has a miss about 1000 rpm and the buck and jerk untill you drive 15 or more miles. Oh by the way no CEL light and no codes i love this thing

Well while I was doing the IPC change I took the FICM appart to check it out.

Never bothered with re-doing it. After removing the two plastic covers off the capasitors on the power supply board I found that one of the FET transistors had exploded and the board was burnt black.

I would say this happende before I replaced the injector harness. The original harness had been repaired by a dealer in West Virginia and the wires just out from the FICM connector wer butt spliced together and rappe with tape befor I bought the truck and I found it while in there fishing a glow plug out of the head. Don't ask, it is a long story too and was a self inflicted oh no.

So Monday I will be getting a new FICM.
