My 05 6.0 quit going down the road and wont start back up. I have replaced fuel pump and filters, cam sensor and tested ficm. what d I check from here? I have no smoke coming out the exhaust

i would check three parts , i have seen a weak ignition coil make this happen, change fuel filter and last possibly either fuel pump or fuel pump regulator

fuel pump pressure test .crank angle sensor test.

My expediton would do this. I would be driving and it would just go dead and I would have to coast to the shoulder. My situation was a fuel pump relay switch located underneath by the spare tire. Problem was it corroded away from road salt and for a while did it intermittently. Ford changed the relay to have a protective shielding on it to prevent this from happening again but it was only a 70 dollar item as I recall.

First check where your fuel pump relay is then check it or have it checked to make sure it works proper. Then check all fuses in the auto to make sure all are good. If after all this checks ou and still no fuel pump sound from the tank if you stick you head close to the tank the pump can be heard. If you do hear a pump running this could be a sign your fuel filter needs changed it is clogged up. if no sound pull the fuel pump and supply 12V power to it on the ground away from the car and gas tank and after it has properly drained of fuel and dried. If this pump works on the ground you may look at your cam sensor. If while you are cranking your car and you see the rpm gauge move this means the cam sensor is reading if you see no movement at all change the cam sensor. Often when the cam sensor goes you may as well change the crank sensor as well to prevent repeating the down time of your car later on down the road.

Check for fuel pressure at the primary fuel filter. there if you move the plug for the fan clutch you can see an auxillary plug on the filter housing facing forward and to the driver side. You should have 40+psi with key on. another way to check the pump is to listen for it to cycle on for 10 seconds or so after key on. Also check for lubricating oil pressure on the cluster gauge and then high pressure oil with a manual gauge. its needs to see around 600psi oil pressure to signal the injectors to fire. best way to check all of these is with a scanner that has data reading, which will also tell you if you have a bad ficm, ecm or sensor connection.

Was the cam sensor tested & was it found to be bad?

Was the fuel pump checked out or fuel pressure checked?

Always learn how things work & how to test them

Replace nothing until something fails

No guessing at all,diagnostic testing, if you like
that langauge

Failed Fuel Pump--my guess

if no check engine lite -check fuel filter,egr valve,cat converter computer

i would test the fuel transfer pump next.

You can get the wiring diagram at www.alldatadiy.com and it will have all the codes and will have the information to test before you order the parts, also have you replaced the fuel pump? fuel sock? it also has two pumps a primary and the secondary check for fuel rail pressure, to test injector remove injector wire and test with digital ohm meter test the power post of the injector to ground. if it read 5 ohms or less it is ok. Have you checked the glow pulgs and glow plug timer is it stuck on removing power from injectors, need more information to give you a better answer.

I would check the cam and crank position sensor, these are definitely the symptoms of a bad crank sensor.
