i think my obd fuse is blown and i know its #12 but which one is number 12.....is there a fuse that blows to make truck not fire

 

Have you checked your FICM voltage? If you're not getting any smoke while cranking it's not getting any fuel. No fuel = no run. There are several conditions that have to be met for the FICM to give the motor fuel. Do you have any kind of diagnostic tool to use?

 

replaced the ficm lastweek..been broke down for 3 weeks now..its got fuel and oil pressure..idk im lost..replaced cam sensor today and nothing still

 

Again: There are several conditions that have to be met for the FICM to give the motor fuel. Do you have any kind of diagnostic tool to use?

 

not on hand..i cant get ahold of the guy that plugs it up for me EVERYTIME it breaks down

 

i dont think our fords have an obd fuse. tee-hee-hee.

but dont fret. ur obd fuse is usually shared with the cigarette lighter, i tink. u find tat fuse for the cigarette lighter, then ur alright, cos i believe the wiring is such tat they are conjoined. funky word, but it grows on anyone. "conjoined". lol.

 

yea i found it...thanks

 

cam sensor and crank sensors dont usually give out tat quickly. usually it's the fuel filters, oil filter, FICM, batteries, alternator, and even the egr valve tat die out before them fellas do.

have u load-tested ur alternator? over 12 volts? good.

load-tested ur batteries yet? they have to be load-tested individually, cos they're arranged in parallel mode. disconnect one to test the other. ideal voltage is usually 12.6 volts for good battery.

then test ficm. we have a test procedure in our tech folders. for me, i have a scangauge. hence, i program the parameters for FMP (ficm main power). i find out real quick if she's alright or not.

oil filter. did u use the motorcraft one? i recommend u do. them generic ones dont work on our trucks.

fuel filters. did u change them out? they're supposed to be changed BOTH at the same time. every 15,000 miles.

 

good. i'm glad u did. or i might have to yell it out from the top of my lungs and hope u hear me from wherever u are. hahahahaha.

 

ficm is good holds 48v...alt and batt are good 12.6ish and filters get changed every 4,000 miles...its weird.im lost

 

what kind of oil filter do u use and wat kind of fuel filters do u use?

 

this is a funny thing, but if she had "died" before from a major problem, like blown egr cooler and blown oil cooler......... maybe u could try hitting the fuel pump reset switch. it's over by the kick panel underneath the passenger side glove compartment.

dont quote me on that, but u could try and see if that works. if all else fails, no offense, but ur truck aint gonna be starting anyway.

 

not sure about what brands cant remember,,but egr is deleted..its weird idk what it could be..if i could get ahold of the guy to plug it up to hid laptop i would but of course he wont answer

 

sorry to hear tat, man. just hang in there. i'm sure a solution will reveal itself. it'll work out in the end. keep the faith.

if u or anyone else uses a FRAM oil filter, there is a very good chance ur truck aint starting is cos of that. it's a strange theory but tats how the cookie crumbles. only the motorcraft and wix oil filters are recommended for our trucks. the 6.0 is tat frigging sensitive.

 

thanks man
