hard start
I just grind the cam plate and turned the pump up and now i have to pump the throttle to start it but after its warm it starts. I think it could be the lift pump because it runs about 12 -15 on idle but when running it dosent change much and when i get in to it goes max to 20-25 and goes down it dosent hold i checked the heater grid its fine i replace ofv it helped with smoking but i dont want to replace if i dont have to but if so i was thinking about putting a 6.0 duramax fuel pump on it because the hold up 55psi so i would kinda be like a air dog just not as $$$.

fass pumps are a waste of money on 12v's. 12v's dont need crazy hi fuel pressure like 24v's do. Yes, readjust your idle. That will help. I'll bet money you dont need to have the go-pedal floored (remember; this is a mechanical truck.. it's doing the same thing w/ your foot partially on it as it is floored). I ALWAYS had to hold my foot just barely touching the go-pedal for it to start when it was below say... 50*.
