  • Re: Holley Sniper EFI

    Hey Guys
    I need a little help. I installed a EFI Sniper Hyperspark system and it runs great for about 25 minutes and then it cuts off like someone turned the key off. The fuel pressure is at 59 lbs, I have checked grounds three times. I talked to Holley they thought it might be the coil because it gets really hot. They sent a new one same result. Has anyone had this issue and if so what did you do to fix it. Greatly appreciated. Richard.

    Tell us a little more about your setup. Stock/OEM ignition, or the Holley CDI? What kind of fuel pump are you running (in-tank, frame mount, surge tank)?

      best bet is either holley tech support forum
      or call them.
      only a few folks using it here.

      that said usually if it just shuts off it's electrical.
      if it doesn't fire right back up likely bad component.
      if it does fire right back up probably a bad connection somewhere.
      since it's time/heat related odds say bad component.

        Just to let you guys know. Holley sent me a new throttle body. The one I had on the Chevelle only had 22 miles on it. Evidently I was lucky enough to get one that would flood with gas and cut itself off. Which also explained why it ran rich. 4 months later running like a champ.Thought I would let you guys know, in case someone runs into this problem.

          My old rig (360) was set up with a Edlebrock Performer, 4 BBL Holley sniper and Hyper spark and I freeking loved it.
          New rig stock for now. Would I be disapointed just adding the 2bbl SNiper and Hyperspark to a stock intake on this 360?
