Find a scan tool and watch your ICP as your starting it.

How do i check my icp ?

How do i check my icp ?

You need a scan tool. The IPR could be hanging up and not allowing the pump to build pressure.

Is my maco scanner suitable an what am i looking for ? Also i checked icp an there was oil on connector so im assuming its bad or going bad right ?

I was going to suggest unplugging it and see it it starts any better, but it shouldn't have any oil in it. It could be going bad

So if my icp is bad this will make the truck hard to start when cold ? Im gunna have to try unplugging the icp tomorrow morning ..like even tho temps are in 60s over night once it cranks over it does like an idle surge once or twice then Clears up

If its not reading the correct pressures then it could. They injectors have to have enough pressure before they will fire.
