HELP Hard Cold Starts
I recently posted on here with awesome responses from some very knowledgeable guys so i thought i would ask some more questions. I have a 2004 F350 with of course the 6.0 powerstroke. The truck has 104k miles on it. Prior to me buying it under warranty ford replaced the turbo at 55k miles. at 98k the previous owner had the number 2 and 6 injector replaced. My last post was no start when cold and at times no get up and go with smoke. Long story short i replaced my FICM because the voltage was at 16 volts. That took care of the starting issues and the no get up and go.
I went to start my truck the other morning it was 41 degress. The truck just cranked and cranked and didnt fire. I tryed a couple times and nothing. There was no smoke out of the exhaust. Then i read on here that if you think it could be flooded to hold the accelerator clear down. I did that and in a few cranks it fired and ran fine. When i crank my oil pressure guage rises to the middle. I have had this happen twice now. last time when it didnt start after 4-5 seconds i hit the pedal and it fired. Once it starts it is fine all day.If its plugged in it starts like normal.
So what could it be? or where should i start? I will say i had an appointment with ford on a monday and friday morning my FICM was dead so i replaced it. I called a family friend that worked at Ford and asked him if the FICM needed have anything done to it and he said the diesel mechanic said no. The place i bought the FICM said it had the latest softwae upgrade.
On another note when it started the first time when i had to press the accelerator down i noticed exhaust smoke come out from under the hood, just a little bit. I have a few times noticed a little exhust in the cab if its had a hard start and idling. This is not everytime. Could my exhuast be leaking to my turbo ? allowing a sensor to not allow it to start? Maybe when you press the pedal down it changes the values and allows it to fire? When its warm the metal is swelled and sealed and i dont have issues?? I have grabbed it and looked as best i can and i cant tell that its loose. Any thought ? I also eel like it doesnt have the get up and go like it did a few monthes ago. I dont have any extra guages.
thanks for your help guys in advance.
