Need expert help
I have an 06 350 6.0. On cold starts it turns over for 8-10 seconds before firing up, it starts normal after the motor is warm..... any ideas? thanks for any and all advice.

i am also no expert by far. but i have heard a lot of stuff and verified a lot of it from my ford friends. i have heard that injector o rings can cause that cold start problem. apparently it lets air into the fuel system and doesn't start right away. but ficm would def be easier to check.....

I had that problem with Injector o-rings
its sufferring from Low Fuel Pressure cuz the Orings didnt seal and fuel escapes from the injector cup causing Low fuel pressure
I knew it because I was making oil and the oil really smelled like Diesel fuel it would make a quart of oil every 2 weeks
It wwould start normal it just ran rough and misfire and tranny wouldnt shift right But everything was fine when warmed up
I reringed all 8 injectors and problem solved
