    Having trouble getting my car to run after installing Holley EFI Sniper system. I installed a new Holley fuel tank with fuel pump inside the tank. Car is getting spark and will start if I spray starting fluid. Do I need a fuel regulator? Is my fuel pressure too high? 1966 Ford Mustang with 302. Getting gas to the throttle body.

    The fuel pressure regulator is already in the Sniper, you may have a faulty one. It's always possible. Do you have a fuel pressure gauge attached to your fuel feed line?

    I do not have a fuel pressure gauge, that's the next step today. Thanks for the replies, I'll let you know.

    Not sure what the issue was, however, it started up and is running fine. Thanks for the reply.

    You need to prime the fuel pump six times (into a bucket) before hooking it up to the Sniper. Did you do that?
