the ficm was replaced recently, so it will be under warranty. didnt get a chance to test it.. i just had it towed basically. i dont have a way to tow my truck back, because our flatbed trailer doesnt have ramps or a winch on it.. and its my only means of transportation for work and stuff so i really had to get it fixed shortly. i will tell the guy to pull the icp sensor and test the ficm though. it acts like a HPOP problem maybe, but im not sure because ive never replaced it or had it fail

where is the icp sensor at?

 

do you hear the fuel pump? kinda thinking what you are but trying the free stuff first

ICP sensor is a pain in the butt on your truck, it's all the way on the top-back of the engine, it screws into the drivers side back of the HPOP cover, the one that is on top of the side of cover is the IPR valve

 

Is this for your 6.0? Might want to let others know that first next time, hard just guessing if it's the truck in sig and trying to diagnose.

Did it shut off on it's own? Or you turned it off, then went to restart and it wouldn't start? Was it puffing smoke at all when you were cranking it?

 

wasnt puffing any smoke at all when starting. yes its for the 2003 6.0, sorry just kinda assumed people would know my bad .

i turned it off, ran inside and grabbed a water, then came back to truck. it was turned off for no more than 5 minutes, went to start it, and it turned over really slowly sounding like it was weak. i checked all my connections and went over any leaks didnt find anything. batteries were fine, fuel/oil levels were perfect. but there was 0 smoke... which is what makes me think it could be a fuel problem..

read this and see if it might be related:

6 days ago i filled up my AC with fri-on (i dont know if i spelled that correctly), thought maybe it was just low but turns out there was a hose with a leak in it. it worked for a few days then quit and became hot again. i was driving around late at night with the air on and started feeling sick. there was a burning smell coming from my air vents, and the truck was making a wierd noise like sandpaper scratching together (thats the best way i can desribe it)... i believe the noise and smell could be related to whats wrong with the truck, and the AC was just another problem not related.. but im not sure... its really hard to desribe things without actually being there but there you go, i gave it my best shot!! thanks for reading along.

 

I wonder if what you smelled was somthing shorting out, the turning over slowly thing makes me think it's a voltage problem.

 

something couldve been shorting out but it went on for a few days any time id turn on my vents. youd think i would see smoke when idling with the hood open or something.. it really blows my mind..

 

Loosen the belt and check your AC pulley to make sure it spins smooth, the bearing in mine went and it locked the motor up at idle, one of the ***** tried to get past the race and was wedged inbetween and locked up, AC wasn't working right before this happened. The AC refrigrant can definately make you sick, take it to a shop and they can use a special lite to find the leak

 

i will tell the mechanic to check that.

the night i started feeling sick i thought i had an exhaust leak and had gotten carbon monoxide poisoning.. it was bad...

just got off the phone with the mechanic.

he said the AC compressor locked up.

he got the truck started and said when it did, the belt broke and wrapped around the fan so he has to take the front end parts out and replace the belt and hes replacing the compressor for me.. anybody know prices on these parts or how many hours it should take to do all this. i dont want to get screwed on labor.

---AutoMerged DoublePost---

anybody...?

 

kind of depends on where he gets them, I think I paid around $60 for the belt and if it's just the clutch that is probably At least a $100 from ford, seen them on ebay for like $60

 

We had to do a quick fix at work once and we just bypassed the ac compressor and put shorter belt on...... wish i seen this before you got towed ...worked yesterday... ac compressors can be expensive.. do you need a air conditioning right now?
