Won't fire ! Ficm?

[powersmoker1429]

So while I was camping my ficm would slowly drop at the end of the trip it was down to 25v while cruising at 70. Now 3 days later went to goto work and all it does is crank won't fire. Would the ficm cause this ?
Thanks guys

Well your FICM is definitely bad! Unless you got some weak batteries! But if you say it is cranking then I doubt they are that bad! I would replace FICM and then go from there! May be all that is wrong with it!

Put the battery charger on it for a couple hrs and it fired up after some long cranks. Runs okay now. Bought the 48v ficm from innovative. Now just wait for the mailman.

Sounds like the FICM to me too, I replaced mine and also the ICP sensor. After both it runs like a champ.

Ran fine last night. Now it does the same thing just cranks and tries to start. Black smoke and fuel in the filter bowl so it's getting fuel. I'm

What year is your truck?Try disconnecting the ICP sensor on startup. This will cause the truck to start properly without the sensor throwing it off. See if that helps.

It sounds like your FICM! Mine just did this to me. I had mine serviced through FICM Repair.com - Your Source for FICM Repair Super fast service, 3 day turn around and I went with the PHP Eco Tune. Total with 2 year warranty was $475.00 It cleared my problem right up! Good luck and keep us posted!
