2003 6.0 friends truck had stereo stolen they didn't trash it too bad but since then it will not start I have no logic input voltage to FICM if I give it voltage at the 10a fuse the FICM puts out a nice 48 volts and starts fine as soon as I take away power dead I have tried darn near everything to trace the this circuit and am now plum outta ideaers

 

It runs to the FICM relay and should energize when that relay energizes. Do you have that diagram? it's a fairly simple circuit.

 

Here's a diagram I drew up to help a guy get a 6.0l running in a Ranger. The pin locations may be different, but this will give you a general idea of how the power is coming and going.

 

Thank You I will give it a go with the new info. Still don't think it's fair to bring electrical stuff to the guy who don't drink.

 

Also Google 6.0l FICM Guide. Good info in that PDF.

On edit, here's a link.

 

Well I now know that I have no power going into relay to engage it the chase goes on

 

anyone have anyideas where the power feed for the ficm relay comes from and if so could this be controled by ford security system

 

Have you checked the 50A fuse that feeds it? I can't attach this PDF I have of the engine electrical.....grrrrrrr

PM me your email and I'll mail it to you

Might be able to see it here: http://www.backglass.org/duncan/ps60...l/ps60_091.jpg

 

check fuse f2-22 and the wiring to the fan clutch

 

WTF took you so long--LMAO

 

man it been rough. I have not pulled the wiring diagram but its pretty simple. the ficm relay has to power polls and 2 ground polls just figure out wich of the 4 is missing and trace backwards.

 

I know it's been hotter than a bitch wolf in a pepper patch there and not much cooler here. Is f2-22 the 50A fuse?

 

This truck is going to drive me nuts I have ignition power to ficm the wires from ficm output to ficm relay are good however I get no output from ficm to engage the 50a relay is it possible that the Gold remote start/theft system maybe messin with me

 

the relay has 4 pin what pin on the relay exactly is not got power. look at the bottom of the relay for the relay pin number.

 

thanks for the help I am not sure what the pin number is it is the on closest to the firewall that receives the voltage from I beleive pin 27 or there about on the ficm I have checked the wiring from the ficm to the relay and it is good I am told that the truck ran fine before it was broken into and the stereo stolen I am looking hard at the alarm system right now. If per chance my friend is yanking my chain in an effort to have insurance fix his truck I may explore other uses for the 48 volts from the FICM
