yes it does have start assist. I meant that once the start assist is activated, it takes like 10 or more times of the starter turning to where it actually fires up. It does always start though. Is there a way to check if this battery is the problem. I already paid to have the ecu updated and some new relays. I don't mind spending a couple hundred to fix the problem, I just hate dumping money in a bunch of parts without having a good way to diagnose it and give me a better shot and narrowing it down. Thanks for your help and to me it honestly does sound like the battery could be the problem, cause althought my worker has a differant vehicle (powerstroke diesel) he did have the same issues and were resolved after a new battery.
