Default Slow to start??
My LS1 will not start on the first try, I have to crank it several times, stop, then crank it again sometimes three times before it will start. Replaced fuel filter and that wasn't the problem. Not sure what to check next. Any suggestions...?

The spark plugs might be shot. Pull'em out give them a look, or just go ahead and throw in another set.

its the pulser "fuel pressure regulator". its the circular thingy on your fuel rails over the intake. replace it and you will be fine.
