hard starting

[Jim D]

My 99 is hard to start when warn. If you turn the key on and off a couple of times it will start. It starts fine when cold, I had the fuel filter/check valve replaced, any suggestions or thoughts, thanks Jim.

what happens? crank slow?

No it cranks fine ,just won't start , till the key is turned on and off a couple of times. I think something is leaking down, fuel injectors, fuel pump,etc.

HI there,
I would start with 2 bottles of Chevron Techron to a full tank of fuel.
It is possible that the injectors are slightly restricted. Do you feel that your idle is a little rough when compared to other LS1 engines????
Allthebest, c4c5
