Re: no start issue
If VATS was bad, car wouldn't turn over. You need to look at fuel pressure, spark, and basics like that.

Re: no start issue
WEll, true - the injector enable signal could go bad I guess but the VATS could still ground the starter enable relay. So see if the injectors fire - if they do, then it's not a VATS issue.

Re: no start issue
If you think you have a VATS issue, can try bypassing it
