? on the 7 pin ficm

Hello I was wondering if anyone could give me some info on the 7 pin ficm.I have read that I need to put my volt meter on the top screw on the 4 screw row.I put my meter on there with the key switch on and got no volts.Even when trying to start,I got no volts on that outer screw.What does that mean and is it ok to test the other screw terminals.My truck is in a no start condition....

Thanks I checked that screw and got no volts with the key on and while trying to start.I've tryed testing multiple time and i get no current on that one.Since it cut off in my driveway and hasnt started back,I havent heard the injectors cycle when turning the key to the on postion.I can get it to fire on a quick shot of ether or a rag with gas.It will run on the fumes and then die.I have had a couple of blue smoke puffs sometimes while trying to start.I have 2 new 850 cca batteries and a new ficm relay..Any ideas....

ficm fuse? Sounds like your ficm might be toast. Not sure what else would cause no ficm voltage. Maybe someone else will chime in here.

There is a 10A fuse in the same location as the relay you replaced in the engine compartment. Not sure if there is another one in the fuse box in the cab or not. Check the owners manual. You should be getting 12V +/- on one of the 7 pins on the ficm. I don't remember which one is the logic power, but if your getting 12V to the ficm and nothing out, I'm guessing you've found the problem.

There are 2 fuses in the engine compartment,I believe one was a 20 amp and other was a 10amp.I have power on the 20 amp fuse and no power on the 10 amp fuse..If that 10 amp fuse is the ficm and it has no power but the fuse is good.what should i look for next??

The 10A fuse is the ficm logic. Also check fuse #103 in the fuse box inside the cab. This is a 50A fuse for the ficm power.

Should I just pull the 50 amp fuse out and test the connectors or should I be able to tell just by looking at the fuse???I know when i checked the 10 amp fuse under the hood it had no power.Would it be ok to test the other screws on the ficm with the volt meter.I figured when my truck cut off that it couldnt be a internal motor part.I guess im on the problem and now i need to figure out why that top right ficm screw has no power.And also find out why that 10 amp fuse under the hood does not have power.
