Spark plugs

Would changing spark plugs in my 07 FJ help difficult starting? Truck runs fine, other than hard starting.

It could, it mite. The first step will be to remove the old plugs and see what they look like. You can tell a lot by looking at ( reading) the spark plugs. Don't get cought up in all of the hype about spark plugs. Just replace them if needed with Denzo OE plugs. Low fuel pressure can and will also make an engine hard to start.
