ficm

[archie]

howdy
just put in a new powersupply (bpd) for the ficm. The truck turned over and idled real rough then died , would not start. I did check ficm with the key in the on position and had 48 v. Now battery is dead. Is it normal to start real hard after changing ficm? When I swapped out some injectors it was the same story...hard to start , which I know is normal.

I am a little worried because one of the ends of the injector harness will not "snap" into the bottom of the ficm , so i will probably be buying a ficm for the logic board from ford.

Any advice?

Should start right up no problem. I'd say that connector is your problem.

I actually took the harness of so I could really get some pressure to snap it in. IT WOULD NOT SNAP / "CLICK" in...pissed , easy job turns into a drag. Can you buy just the logic board half of the ficm? If I have to get a whole new ficm from ford should I still use the bullet proof power supply? I was thinking yes because it is non returnable anyways. 500 dollars tuns into 1000 wtf ha ha ha.

thanks

Take all of the connections out of the FICM and try again. They can be a pain to get seated in but just get at it. It will click in and should fire right up. If your batteries are dead than that could be a major problem as well.

I doubt it the FICM itself. I'd completely remove the FICM and inspect the plug.

i tried like 10 times. like i said i even took off a few of the connectors to the injectors so i could reef down on the middle connector to the ficm. It will just not "snap" Don't know if it is the harness or the ficm. some of the gray insulation on the inside where the connecter goes is worn away but other than that , everything looks okj?

thanks

Just walk away for a bit and try again later. You'll get it

Thanks, I did. For just a bit it was a toss up between throwing things or crying. I will try tomorrow but I am sure it's either the harness / plug is broke or it's the lower half of the ficm

thanks again

Trust me when I tell you those plugs can be a serious PITA sometimes especially if not lined up perfectly. Try working from the back to the front.

I hear what you are saying, i had the ficm totally out and the harness unhooked from the injectors so i could line it up perfect and squeeze the sh1t out of it , it looked to be home, it just would not snap. i will try tomorrow. but first i will get a new ficm and an injector harness and leave them in the bag.

thanks much.
