Pulled the trigger on a Holley Sniper today

The problem with the aftermarket F.I. is when it won't start what failed. At least with the carb either there is fuel or not. I put in a tanks inc. tank and pump and car sits for 2 weeks and starts right up after running pump with the carb. I got stuck with F.I. and had to send it back to have it repaired. While it was gone put carbs back on and got it running again.
