Repairing FICM harness connectors
 

Trying to do a bunch of stuff to rule out problems before I may have to face up to an injector (engine knocks, especially when rpms drop as engine goes into 5th gear.)

One FICM connector was broken and tried a zip tie repair. Didn't work.

I found these 3 replacement connectors. Each is $30+/-.
Anybody know which is which? Are they for X1, X2 & X3?
Has anybody done the swap? Looks like it could be a royal pain.

2003-2009 International VT365 FICM Connector part ap0018
2003-2009 International VT365 FICM Connector part ap0019
2003-2009 International VT365 FICM Connector part ap0020


Then I find 3C3Z-9D930-AA for $71.
Is this the whole FICM harness? I can't get a picture.

Is 3C3Z-12B637-BA the whole harness? I see that for $240.

I can't find a good photo or description of these items online and I can't get down to dealer parts dept for a few days.

change the harness > ebay $90

Which part is broken? It looks like the clip from the male portion is still there.

I've seen a lot of connectors that have turned green from corrosion and lost continuity because of the corrosion, could that be your problem?

I really don't know what the problem is. I don't have scan equipment or code reader tool yet ... although tax rebate comes in soon!!

The truck has no CEL and starts fine. Then it shakes at idle. Shake somewhat noticeable when driving. Shake EXTREMELY noticeable when speed is around 45mph and rpm's drop back to 1,100ish ... so I guess it's going into 5th.

Took everything apart again today. All pins were fine and connectors were clean. This was the only thing I could point to.

Rev-X is on its way in the mail as we speak. I hope that may help. Right now the truck is a giant paper weight.

Does a FICM loose it's programing if it sat around disconnected from the vehicle for about 2 weeks in the cold?

Go on ebay entire ficm harness 100.00. or try salvage yard found mine 25.00.

I hope the text in red is helpful enough.

Thank you Sir!!
Huge help!

Kinda sounds like an ICP issue with the shaking at speed. Mine did a little jerking around 60-70mph and the new ICP fixed that.

The ficm (unless something else happened) will keep it's program.

Rev-X will help if it's an injector problem but it's just a band-aid. I run it and love it but I know it's just a matter of time before I'm back into it putting in new injectors.

That's what started all this. I just replaced the ICP and connector.
The oil leak's gone and the rpm's have settled down.
Maybe I messed up splicing the connector :confused:

Boy that would suck. Hopefully its sunny on Saturday.

?Maybe. You mentioned that you don't have a scanner so it's going to be hard to tell. I watch my ICP on my scangauge to make sure it's reading but I don't know if there is a trick to figuring out if it's reading without a scanner???

May be time to get a scangauge and see where it's at. I dunno but your symptoms sound like mine when I had the ICP going out. I got a scanguage off Amazon.com for $200-ish (don't remember exactly) but it was one of the best buys I've ever made for a car.

I can't recall - I assume your truck is an '03 or early '04?

Early '03. ICP at rear of engine.

I'll shameless plug my last overly descriptive post on this ...

..... this is the full story. :-tap

If an injector(s) didn't just stick or fail over night then I think I must have messed something up I guess. Maybe I was too rough with the harness when I had it pulled back to do the splicing. :confused:

This weekend I'm going to splurge on an Edge insight CTS.

I hate posting without being able to supply parameters. Plus it'll finally give me some of the gauges I should be viewing too.

Any help or suggestions appreciated.

Working again!!
 

Problem solved.

Spent a good hour today online trying to price harnesses, or connectors, looking to get a scan tool, thinking I'd have to get injector(s), trying to figure out how I might pay for it all. Feeling pretty down.

Went outside to redo my work just one more time, just in case, and found the connector on the injector closest to the firewall wasn't on properly :-X19

Thankfully the clip was still on it.

Plugged it in and now it runs just fine. ICP done! 3 weeks later!!! :-drink
